In this chapter, we will meet Russel, the ABAP developer, as he begins to explore his newly upgraded development system. His exploration is cut short, however, as he learns of a new project that will force him to channel his development skills into new directions.

Workbench Tools and Package Hierarchy1

This is a very exciting day for the ABAP developer, Russel. Today is the first day that Russel gets to log onto and explore his newly upgraded ABAP development system. This is something he has been anticipating for quite some time.

For several years, Russel has worked diligently on his employer’s SAP R/3 system. His employer is a university that implemented SAP R/3 over 10 years ago. Origi-nally, they implemented SAP R/3 primarily for financials. Over the years, they have expanded their use of SAP R/3 into human resources and purchasing.

Russel has worked on all kinds of custom development projects. Early on, he worked primarily on reports and data migration programs for the university. As his skills in ABAP grew, however, he found himself working on increasingly more complex projects. He is quite proud of some of the systems that he has custom developed from scratch in the ABAP environment.

Like many SAP customers, however, the university has stayed with the 4.6C release of SAP R/3 for many years. Still, Russel has kept up with his reading about the new features that were introduced in SAP Web Application Server (SAP Web AS) 6.10 and 6.20, SAP NetWeaver 2004, and SAP NetWeaver 7.0 (and the enhance-ment packages that came for SAP NetWeaver 7.0), and he has seen many fine new developments emerge over various ABAP releases. But because he never had a system or projects to work on at these release levels, he feels a little like he has been looking in from the outside. He can see these great new features, but he never gets the opportunity to try them out for himself.

Log on and Explore1.1

Like any good ABAP developer would do, Russel goes immediately to Transac-tion SE80 —the ABAP Workbench—when he fi rst logs on to the newly upgraded system. Of course, there are many other interesting capabilities to look at, for example, the Internet Communication Manager (ICM) confi guration in Transaction SMICM and the service node hierarchy in Transaction SICF ; however, Russel will have to wait until later to investigate these components.

Workbench Object Browser1.1.1

When entering the ABAP Workbench for the fi rst time after an upgrade, Russel sees a familiar-looking interface (see Figure 1.1).

The classic layout of the object navigation tree on the left side of the screen and the object editor on the right side has not changed. You can still navigate through

Log on and Explore 1.1

your object view history, up and down the package hierarchy and by drilling into objects via double-clicks.

The optional subwindows Display Worklist and Navigation stack are also dis-played . Russel has already activated these two features back in SAP R/3 4.6C, so they are still present with his last entries after the upgrade. Because these features of the ABAP Workbench are optional, you can activate or deactivate them any time via the Utilities • Worklist or Utilities • Display Navigation Window menu options.

Like many ABAP developers, Russel likes to use the worklist to keep track of the items he still needs to fi nish or come back to and test. The navigation stack is another quick way for him to see what objects he has viewed lately. As you will fi nd, for example, when you’re using forward navigation to jump between objects frequently, this tool can be very helpful to keep you from getting lost in a deep stack.

Object Browser List1.1.2

But Russel’s attention is drawn to the new Object Browser list area (see Figure 1.2). This is the area with rows of buttons at the top-left section of the ABAP Workbench that allow developers to choose their object browser perspective.

Object Browser ListFigure 1.2

In SAP R/3 4.6C, you only had the Repository Browser perspective. This view, which allows you to work with core development objects such as classes, pro-grams, and Data Dictionary objects, is still the most commonly used perspective. However, by glancing at the other options, Russel gets a quick preview of some of the expanded functionality now available in the ABAP environment thanks to the upgrade:

Enhancement Info System and Enterprise Service Browser EE

The first and the last options displayed in Russel’s Object Browser, as shown in Figure 1.2, were introduced with SAP NetWeaver 7.0 and are specific to new functionality in this release. The Enhancement Info System pertains to the new Enhancement Framework. Although Russel has only done limited reading about the Enhancement Framework, he can tell that selecting this view causes the Object Browser to display enhancements that have been implemented in his system. To Russel, this seems like a new, easy way to keep track of all of his enhancements in one place.

The other new option introduced in SAP NetWeaver 7.0 is the Enterprise Ser-vice Browser. Russel suspects that this is the main Object Browser perspective that he would use when working with Enterprise Services. Once someone con-figures a connection to the Enterprise Services Repository of SAP NetWeaver, this browser can be used to get a view of all possible Enterprise Services that can be consumed from ABAP. Russel is fairly certain he will get an opportunity to use these Enterprise Services in a future project, but little does he know just how soon that will be (see Chapter 5 for more details on using the Enterprise Service Browser).

Test Repository EE

The penultimate option in the list is the Test Repository. This item was intro-duced with SAP NetWeaver 2004. This is a view of your ABAP Unit test classes. Russel is a little skeptical about the idea of coding extra unit test classes. He has always done his own “black box” testing informally before handing off any development to the functional owner for extensive integration testing. He has never put much thought into a more formalized test process. However, with the upgrade, he is open to trying out lots of new ideas and does not want to dismiss the idea of unit test classes before he has had a chance to try them out in a first project. Russel’s first experiences with unit test classes are covered in Chapter 9.

MIME Repository and Tag Browser EE

The remaining options in the Object Browser selection area date back to the early 6.10 release and 6.20 release of the SAP Web Application Server. The second and fifth options in the area, MIME Repository and Tag Browser, come hand-in-hand with the introduction of embedded web functionality in the ABAP environment.

MIMEEE stands for Multipurpose Internet Mail Extensions and was a specifica-tion originally developed for the transmission of non-ASCII7 characters via

352 Book.indb 32 12/6/10 2:59:46 PM

33


SMTP. Although originally conceived as part of the Internet mail standards, MIME is also the core standard for communicating any nontext data via HTTP. For instance, any JPEG images used in the output of a web page would be stored in this repository. Unlike many other web servers, ABAP does not store these MIMEs at the file system level. This would be very complicated, given the multiple–application-server arrangement of most ABAP-based applications. Instead, the MIMEs are stored in the underlying database. However, the MIME Repository view in the Object Browser displays the organization of the MIME objects in the familiar file/folder structure that we are all used to dealing with.

Because web page design is generally based on HTMLEE , it makes sense to also have a Tag Browser. Tags are the descriptions of user interface elements that you want to appear in your web page. For instance, an input field is formed by adding the <INPUT> tag to your page’s source. In addition to displaying all of the standard HTML tags, SAP also uses the Tag Browser to organize all of the BSP-specific tags (Business Server Pages, an ABAP-specific tool for creat-ing web pages), also known as BSP extensions.

Russel has always been the tried and true ABAP developer focusing on list and dialog programs. He has never experimented much with creating web pages, unless you count the time he created an HTML page to share pictures of a fam-ily reunion. Nevertheless, he realizes that the time when an ABAP programmer could turn a blind eye to web development has passed. He knows the future of ABAP development will require him to learn about the new browser-based UI technologies such as BSP (see Chapter 15) and Web Dynpro (see Chapter 13 and 14).

Repository Information System and Transport Organizer EE

The remaining two options, Repository Information System and Transport Organizer, are not entirely new tools. Both existed before, but now they are integrated directly into the ABAP Workbench.

The Repository Information System gives you a higher-level view of the orga-EE

nization of ABAP development objects. It allows you to search for objects based on their assignment to an application area, such as Materials Manage-ment (MM) or Sales and Distribution (S&D). This application–area-based hier-archy is most useful when you’re trying to find some standard SAP objects that you might want to access or reuse in your own development projects.

The Transport Organizer brings the most common functions of the trusty EE

Transaction SE10 directly into the ABAP Workbench. For instance, you can

352 Book.indb 33 12/6/10 2:59:46 PM

34


now release transport requests or view their contents from the ABAP Work-bench. Although this is not state-of-the-art new functionality, the possibili-ties for integration make this a welcome usability enhancement.

Workbench Setting1.1.3 s

Just about the time Russel fi nishes exploring the different Object Browser views, one of his fellow developers, Nathan, stops by his offi ce and notices that Russel is exploring the newly upgraded system. Nathan immediately detects that Russel’s screen looks quite different than his own, even though they have both been work-ing on the newly upgraded system this morning. Russel explains that it is possible to confi gure several options for the look and functionality of the ABAP Workbench from the menu options via Utilities • Settings (see Figure 1.3).

Workbench Options – Browser SelectionFigure 1.3

First, Russel shows Nathan how to choose the browser selections that they want to appear. You can confi gure the Object Browser list that we just looked at in detail, or remove items that you would seldom use.

New ABAP Editor1.1.4

Russel then asks Nathan if he’s had an opportunity to try the new ABAP Editor . Although Russel has seen articles on the new editor on SAP Developer Network

352 Book.indb 34 12/6/10 2:59:47 PM

35


(SDN; http://sdn.sap.com), he might not have realized that there was a new editor in this release if he had not navigated through the Workbench Options screens. In many systems, the new editor is not selected by default; however, after select-ing the Front-End Editor (New) option in the ABAP Editor tab, subtab Editor, of the User-Specifi c Settings dialog, as shown in Figure 1.4, he was able to start exploring the new editor.

Workbench Options – Editor OptionsFigure 1.4

Editor Requirements

First, you should note that the new ABAP Editor is delivered in two parts. The fi rst requirement is the software that runs on the developer’s client machine as part of the SAP GUI for Windows . This frontend control for the editor was delivered for the 6.40 (and higher) release of the SAP GUI as of patch level 11. So, before using the new ABAP Editor, you need to ensure that your SAP GUI is up to date.

However, having the correct SAP GUI version alone is not enough. The back-end integration into the ABAP Workbench requires ABAP coding that is delivered along with the ABAP system’s release level. The new editor integration into the

352 Book.indb 35 12/6/10 2:59:48 PM

36


ABAP Workbench was originally delivered only to SAP NetWeaver 7.0 and higher releases.

This means our friend Russel has the necessary release level and SAP GUI to use the new ABAP Editor.

Editor Backport

However, if you don’t yet have SAP NetWeaver 7.0, don’t lose hope. Due to popular demand for the new ABAP Editor, SAP has backported the development to SAP Web AS 6.20 and SAP NetWeaver 2004. This backport was delivered to customers via Basis Sup-port Package 59 for SAP Web AS 6.20 and Basis Support Package 18 for SAP NetWeaver 2004.

Editor Features and Functions

Because Nathan has never read anything about the new editor, he asks Russel, “So what is so great about this new ABAP Editor?” “Plenty,” says Russel. He goes on to explain that because the new editor is primarily a piece of software running inside the SAP GUI on the user’s PC, it brings with it a lot of user interface enhancements. Furthermore, the new ABAP Editor has the kinds of functionality that have been standard for years in other development environments.

For example, you now have code coloring and syntax highlighting. This frontend control that is the code editor is no longer just a text editor. It understands the ABAP language syntax and contains a mini-compiler. So, as you type, the source code is constantly being parsed and processed on the frontend to apply syntax-sensitive formatting.

For instance, you’ll see keywords being formatted with a different text color than comments or data variables. You also have the ability to do code collapse; for example, you can take a complex IF statement and collapse the entire structure. This hides the inner complexity of the statement, making the overall flow of the application more readable. At the same time, you can quickly see the contents of the collapsed area via a popup dialog when you mouse over the area, which is shown in Figure 1.5.

The new ABAP Editor has numerous other usability enhancements such as a built-in split screen view, an extended clipboard, bookmark and breakpoint integration, customizable code templates, and markers to indicate the changed sections since your last save.

Code Completion

There are some additional treats in store for Russel. His newly upgraded system also contains the latest SAP NetWeaver enhancement package level—SAP NetWeaver 7.0 enhancement package 2. There have been a lot of new ABAP features devel-oped since the introduction of SAP NetWeaver 7.0 in 2006. The vast majority of these features fi nally come to SAP Business Suite developers with this latest enhancement package. One of these new features that impact the ABAP Editor is the inclusion of true syntactical code completion in the ABAP Editor. This func-tionality is similar to the pattern insertion functionality that many developers are familiar with today, but is now available to the developer with just a click of the mouse. This brings the robust object completion or smart insertion found in other development languages to the ABAP environment (see Figure 1.6).

352 Book.indb 37 12/6/10 2:59:48 PM

38


New in SAP NetWeaver 7.02—Code CompletionFigure 1.6

The difference with the ABAP environment is that it uses many global objects. Inside an ABAP object class, you might reference any number of Data Dictionary objects, function modules, or other global classes without the need for any forward declarations. Yet the code completion and quick info of the new ABAP Editor is able to make a call from the frontend to talk to the backend server and retrieve these details on demand.

This code completion is fairly easy to use. As you are typing you can press [Ctrl]+ [Space] at any time to ask the system to build a list of possible completions. This works for a wide variety of objects: classes, methods, function modules, Data Dictionary objects, and so on. The search for completions covers both local decla-rations and the entire global repository. You can then click the item from the list you want to insert (or press [Tab] on the selected item) and the name of the object will be inserted. If you want a pattern insertion (for instance, the entire method

352 Book.indb 38 12/6/10 2:59:49 PM

39


signature instead of just the method name), hold down the [Shift] key while you click on the item or press [Tab].

However, code completion isn’t limited to just the calling of external modules and Data Dictionary objects. All ABAP keywords can also be used within the comple-tion action. The quick info that is displayed for keywords contains the fi rst few lines of the online help. There are also a few wizards that are triggered when you choose the [Ctrl] + [Space] pattern insertion for the completion on a keyword. The classic messages and write statement wizards fi re for their corresponding keywords.

There is also a new TYPES generator wizard. This wizard (shown in Figure 1.7) assists you in creating in-line type defi nitions that are based upon Data Dictionary structures. It displays all of the elements in a chosen Data Dictionary structure and allows you to select which elements you want in the generated TYPES statement. You have an active preview of the generated output that changes as you select or deselect any elements.

ABAP Type Builder Wizard Triggered by Code CompletionFigure 1.7

352 Book.indb 39 12/6/10 2:59:50 PM

Another nice feature of the code completion in ABAP is that the templates, used for both the quick info display and the pattern insertion, are customizable. Sim-ply execute the function module SRCC_CALL_TEMPLATE_MAINTENANCE to access the template maintenance application. In the top of the editor screen (Figure 1.8), you choose which of the two template types you want to work with and then which template. If you check Use Customized Template, then you can edit the system-provided template. This customized version will be used automatically for just your user ID.

ABAP Code Template MaintenanceFigure 1.8

Additional New Workbench Tools1.1.5

The new ABAP Editor alone is enough to get Russel excited about the upgrade, but he knows he has other new tools to explore in the ABAP Workbench as well.

352 Book.indb 40 12/6/10 2:59:51 PM

Source–Code-Based Class Editor

Long-time ABAP developers, like Russel, are probably already familiar and com-fortable with the current class editor. Most of them even take for granted that the form-based approach to class editing—with its separate dialog screens for each method interface and coding blocks—is somewhat standard because that is all we have ever had for global classes in the ABAP environment. However, developers from other programming languages are generally used to a class editor where the entire structure of the class and code are all represented in one editor window.

As of SAP NetWeaver 7.0 enhancement package 2, ABAP developers now have the option to switch between these two types of editors as SAP introduces the new source–code-based class editor. From the traditional form-based editor, you can click the Source Code-Based button (Figure 1.9) to switch editor modes.

Trigger to Switch Class EditorsFigure 1.9

Once in the source–code-based class editor, you will see one large ABAP Editor win-dow that contains the entire contents of the class. This is somewhat similar to the public/protected/private source code view that was possible in previous releases. However, in this previous approach you could only edit one visibility section at a time, and you could only edit the class defi nition, but not the implementation. The new source–code-based class editor removes all of these limitations, allowing you to edit all parts of the class at once.

This is particularly nice because of the easy visibility between multiple methods within a class (see Figure 1.10). However, it can make it somewhat more diffi cult to navigate between the different parts of the class if you use the source code window only. To help with this, many developers may fi nd that they use the object naviga-tor more often for inner class navigation. There is also a special Class/Interface Navigator (shown in the dialog on the left side of Figure 1.10) that you can run in a separate window, allowing direct navigation to different sections of the class.

352 Book.indb 41 12/6/10 2:59:51 PM

42


Source–Code-Based Class EditorFigure 1.10

Luckily, both class editor types still exist within the ABAP Workbench, and you can freely switch between them while editing a class. This lends itself to developers being able to take advantage of the strengths of each of the editor types. You can also choose your default editor type from within the workbench settings we looked at earlier (the class settings Figure 1.11).

Web Dynpro ABAP

The tool that makes Russel positively giddy with anticipation is Web Dynpro ABAP. He has already read so much about it. He knows that Web Dynpro ABAP is the new default UI development tool for ABAP going forward. Although Web Dynpro is a tool that creates development objects that can be run within a browser, it isn’t tied to just that delivery mechanism. Nor does it require that an ABAP developer learn anything about HTML or JavaScript. All of the inner com-plexities of the UI coding are hidden behind a simple and uniform metamodel for describing the user interface. Although Russel doesn’t have time today to navigate throughout Web Dynpro (he’ll get his chance in Chapters 13 and 14), he’s seen enough to know that he’s looking forward to working on a project that employed this tool.

The screen designer alone, shown in Figure 1.12, made Web Dynpro ABAP devel-opment look very appealing. Note that all the UI elements are in well-defined groups on the left side of the designer. In the middle, you’ll see a WYSIWYG editor (what you see is what you get) of the screen as it is being built. You can even drag and drop UI elements directly on this area.

Web Dynpro ABAP DesignerFigure 1.12

352 Book.indb 43 12/6/10 2:59:52 PM

44


On the right side of the screen you’ll see the hierarchy of the UI elements. Russel thinks the drag and drop from the toolbox is a nice feature, but when working with a complex layout, he realizes that this element hierarchy will be the best way to interact with the design.

Russel is further impressed by the property box for each UI element. Although common in other development environments, this property box is one of the few places in ABAP where you can easily configure all of the UI element properties. Ultimately, Russel feels like he can be much more productive designing transac-tions’ screens in the Web Dynpro tools than he is today using the ABAP Dialog Screen Painter.

Business Server Pages

As it turns out, Web Dynpro ABAP is not the only way to create content in the ABAP Workbench that is targeted for deployment to a web browser. When the Basis layer was renamed SAP Web Application Server (SAP Web AS) with release 6.10, it was more than just a name change.

SAP added full web server functionality to the core ABAP stack through the addi-tion of the Internet Communication Manager (ICM). This underlying technology is used as the core communication channel for Web Services and Web Dynpro ABAP.

But, unlike Web Dynpro, where you can’t directly access the generated UI cod-ing, the Business Server Pages (BSP) tool (shown in Figure 1.13) is a Web-specific development environment. Using this perspective of the ABAP Workbench, you can code custom HTML and JavaScript pages. In Chapters 13, 14, 15, Russel will get the opportunity to see how both tools can be useful for creating different kinds of browser-based applications.

Extensible Stylesheet Language Transformation

As Russel is navigating through some of the new object types in the ABAP Work-bench, he encounters the Extensible Stylesheet Language Transformation (XSLT) editor—all of which Russel will end up using in Chapter 11. XSLT is a language that is specifically designed for transformations involving XML. XSLT is not something that SAP invented; instead it is an open–standards-based language that is found in many development environments. You should think of XSLT as a manipulation

352 Book.indb 44 12/6/10 2:59:52 PM

45


language for XML (i.e., it’s a way to defi ne an easy path for creating new XML or XHTML structures from an existing XML).

SAP also added the XSLT language processor to the ABAP Kernel and a com-plete XSLT editor to the ABAP Workbench. One of the major benefits to XLST of being integrated into the ABAP Workbench is that an XSLT object is now stored like any other object in the ABAP repository. This also means that XSLT objects are transported via the Transport Management System (TMS) like any other object. Transformations are tightly integrated into the ABAP cod-ing environment and can be called within any piece of coding using the new statement CALL TRANSFORMATION . However, in the ABAP environment, there is the added capability of being able to transform native ABAP data types to and from XML as well.

Refactoring

The concept of refactoring is not new to the ABAP environment. Every programmer, at one time or another, has had to make changes to a program to better organize its structure. In the early days of ABAP, Russel used to have to work with programs that got too large over time. Consequently, he would edit them to move some of the functionality into more manageable forms, and, when necessary, group the forms into separate includes.

All of the aforementioned activities fall under the concept of refactoring; however, refactoring as a normal development practice has really taken root with the advent of object-oriented programming. It is increasingly common to have to refactor your class structures as they grow larger. This often means breaking up a single class into multiple parent/child classes and reassigning the original set of methods among the new class hierarchy.

With the SAP NetWeaver 2004 release, SAP began introducing some basic refac-toring tools within the ABAP Workbench, which is the only available option that enables you to move methods between parent and child objects. You can access the Refactoring Assistant within the Class Builder from the menu Utilities • Refactor-ing Assistant.

Future Functionality

With future releases of SAP NetWeaver, SAP plans to expand the toolset offered within the area of refactoring. Not all of the new features in the ABAP environment have been backported to SAP NetWeaver 7.0x codeline even as of NetWeaver 7.0 enhancement package 2. The refactoring functionality remains one of the few features that is only available in SAP NetWeaver 7.10 and higher. Figure 1.14 shows some of the new refac-toring tools available for standard program code.

One example of this new refactoring functionality will be the ability to rename a method or function module. The Refactoring Assistant will do more than simply enable you to perform a find and replace operation. It will allow you to change all references to the object that is being renamed globally, even if that means changing other development objects. These future refactoring tools will also have a preview option that allows you to gauge the scope of your changes before you make them.

ABAP Development Tools—Based upon Eclipse

Russel might not have it in his 7.02 system yet, but he also heard about an exciting new tool for ABAP developers at TechEd last year. SAP is currently working on an ABAP development tool that is based upon Eclipse. This is something that is still in early development, and SAP hasn’t commented on when it might ship to ABAP developers, but Russel is hopeful that he will see it sometime in the future.

For anyone already familiar with the industry standard Eclipse IDE framework, ABAP development in this new tool would be instantly identifi able. Figure 1.15 shows a preview of this new toolset based upon a work-in-progress internal SAP version of the tool.

ABAP Development Tools—Based Upon EclipseFigure 1.15

Debugger1.1.6

Every developer knows that a critical part of any development environment is its debugger . With SAP NetWeaver 2004, there is a new debugger that keeps up with much of the great new innovation found in the rest of the ABAP Workbench.

Before SAP NetWeaver 2004, the debugger was limited in what kinds of UI con-trols it could use because the debugger actually ran within the same execution space as the program it was debugging. Therefore, if the debugger contained UI controls that required a control fl ush or commit work , they could disrupt the fl ow of the application that was being debugged.

352 Book.indb 48 12/6/10 2:59:56 PM

49


SAP solved this program by making the new debugger a two-process debugger . Therefore, the debugger now runs in a separate work process and remote attaches to the application that is being debugged. This opened up the opportunity for tremendous innovation in a debugger that had seen few changes over time.

When trying the debugger for the fi rst time, Russel notices that the code is dis-played using the new ABAP editor as long as the system meets the requirements (described earlier) to have the new editor. The additional functionality provided includes your being able to mouse over a variable and see its type defi nition and current value (see Figure 1.16).

New ABAP DebuggerFigure 1.16

352 Book.indb 49 12/6/10 2:59:56 PM

The new debugger is also modular. There are several preconfi gured desktops with a selection of the debugger tools on them; however, any developer can choose what tools he wants and how he wants them arranged on the screen. You can save these custom desktop arrangements of tools for future debugger sessions.

Besides all of the traditional tools such as the ability to drill down into structure and internal table values or see ABAP object details, the new debugger also has a suite of highly specialized tools. For instance, internal tables can be downloaded to Microsoft Excel for further comparison. Figure 1.17 shows the built-in comparison tool, accessible via the Diff tab in the debugger, which allows you to make some very powerful comparisons, even between two internal tables, without ever leav-ing the debugger.

ABAP Debugger Variable ComparisonFigure 1.17

Debugger XML Viewer

XML processing is becoming increasingly more prevalent in normal ABAP pro-gramming. It is commonly used in web development and Enterprise Services , and it is just a matter of time before you will be able to view the contents of an XMLstream in the debugger. XML streams are frequently stored in memory as binary strings , making them nearly impossible to interpret in the old debugger. Figure 1.18 shows the capabilities of the new debugger, which includes its ability to not only translate binary strings, but also to display XML streams in a more readable format for users.

Web Dynpro ABAP Debugger

Lastly, with the introduction of Web Dynpro ABAP with SAP NetWeaver 7.0, we have a whole new type of object to potentially debug. Fortunately, the ABAP debugger works just as well within applications that run in a browser. By setting an external breakpoint , you can debug Web Dynpro ABAP, Web Services, and BSP applications easily and without requiring additional setup on the server.

Web Dynpro goes even further by introducing a special debugger tool (available as of SAP NetWeaver 7.0 SPS9) for interacting with a Web Dynpro component. Figure 1.19 shows this tool in action. The special Web Dynpro ABAP debuggertools allow you to view the component structure , UI controls and their properties, and even the context at runtime.

Package Hierarchy for the Project1.2

Unfortunately, Russel’s fun exploring the upgrades to the ABAP Workbench has to draw to a close. Along with the SAP Business Suite 7i2010 upgrade , the university he works for has an ambitious new custom development project. Russel will have to turn his attention to this new project.

Still, he feels that even this brief run through the ABAP Workbench has provided him with a good foundation. In actuality, he hasn’t even begun to scratch the sur-face, given all the new tools he will be working with over the next few weeks.

When Russel arrives at the project kick-off meeting, he’s surprised to see so many people in the room. Because he hadn’t heard a thing about this project prior to the meeting, he assumes his role would be relatively insignifi cant. The product owner quickly dispelled that idea after announcing that the university had decided to create an online continuing education program. The action items for the ABAP

352 Book.indb 52 12/6/10 2:59:58 PM

53

Package Hierarchy for the Project 1.2

development team were to support this effort with several key pieces of new development.

Project Requirements1.2.1

First, the students in this new program would have to register for the online pro-gram via the existing registration website. The student records would be stored in a separate system that holds the traditional student records as well. Likely, some form of interface will have to be written to access this existing, legacy student database.

The new system will require a self-service website where professors can go to maintain details about the courses they will teach and contact information. The professors have also requested an easy way to communicate their weekly course assignments to their online students. And the administration office wants a new system to track the course registrations so they can run some basic accounting reports to gauge the success of the new online program.

The administration workers already are heavy SAP GUI users and want their reports to be integrated with their existing SAP GUI transactions. For all of the self-service functions that the professors will use, they want to be able to access these pages via single sign-on (SSO) using the new role-based SAP NetWeaver Portal. Lastly, any web pages that are externally facing to the students need to run with no assumptions about what Internet browser the user has. They will need to be able to support many simultaneous users as well.

When Russel leaves the meeting, he understands that he certainly has his work cut out for him. He’ll have only a few weeks to build this entire online system from scratch. At the same time, he still wants to use this opportunity to learn as much as possible. He already knows he wants to separate the business logic from the user interface layer. By creating a single set of business–logic-based model classes, he can reuse this same logic throughout the different user interface technologies that he’s already imagining will be needed to fulfill all of the user requirements.

Package Hierarch1.2.2 y

After returning to his office, Russel wants to forge ahead and lay down the founda-tion work for the project while everything is fresh in his mind. Even though he has only been to the kick-off meeting and doesn’t have detailed requirements yet, he thinks he knows enough to begin structuring his package hierarchy.

352 Book.indb 53 12/6/10 2:59:59 PM

54


In release 4.6C and before, all ABAP development objects had to be placed into a development class . However, this development class didn’t afford much function-ality other than the ability to group objects together in a folder-like structure. To further limit the usability of development classes , it was not possible to nest the objects within each other to create any kind of hierarchy.

However, with subsequent releases, the concept of the development class was renamed package. This is more than just a name change for semantic reasons, because the package assumes far more functionality and importance than its devel-opment class predecessor.

First, packages can be nested to create package hierarchies, and that was exactly what Russel intends to do. He wants to create one high-level package for all of the development objects that will make up this online Course System. Then he wants to logically group the remaining objects into separate subpackages under the main package.

He starts out in the ABAP Workbench and selects the option to create a new pack-age, as shown in Figure 1.20, from the Development Coordination tab of the Object Selection dialog. This fi rst package, ZCOURSE_SYSTEM_V2, would be desig-nated as a Main Package in the Package Type fi eld. The values in the Transport Layer and Software Component fi elds are proposed by the system and almost never changed in customer systems.

The Software Component fi eld is primarily used in SAP systems to separate development objects between layers, such as the separation between Basis and application objects. The transport layer is used in development systems that have multiple transport landscapes. This is also extremely rare for all but the largest of SAP’s customers, in which case the possible values for the fi eld are customer specifi c.

Package CreationFigure 1.20

Package Hierarchy for the Project 1.2

Figure 1.21 shows the package hierarchy that Russel has initially come up with:

First, he wants to separate out all of his Data Dictionary objects and the classes EE

that will directly access the Data Dictionary into the package ZCS2_DDIC.

Next, he will establish a separate set of packages for all of his business logic, or EE

model classes called ZCS2_MODEL. The subpackage, ZCS2_MODEL_ESOA, under the business logic package, will house the Enterprise Services that will be wrappers for his core business objects.

Lastly, he wants a separate layer of the package hierarchy for the user interface EE

objects. Within this level of the package, ZCS2_UI, he can then further segregate between the different UI technologies that he plans to utilize.

Package HierarchyFigure 1.21

“So why,” you may ask, “should he go to the trouble of organizing his objects into this hierarchy?” As you know, segregating objects makes the development more organized, which in turn, helps support the solution by making it easier to fi nd the individual development object components.

Furthermore, this package hierarchy has additional benefi ts. By using the package concept, you can control which objects are visible to other packages (i.e., perhaps not all development objects should be publicly visible or accessible). For example, you might not want any outside programs to be able to access your database layer directly. Instead, you want them to pass through your model class for proper busi-ness logic validation. You can therefore create package interfaces that expose the

Data Dictionary objects only to the model class, but still present all of the model class objects globally. Figure 1.22 shows one of the package interfaces that Russel will eventually create to limit which of his development objects should be accessed from objects outside his package hierarchy.

Package Interface to Control Visibility of Inner ObjectsFigure 1.22

With the packages created in advance, Russel has established a sound foundation for the rest of his development. Next, he’ll begin the project wholeheartedly by creating his fi rst development objects within these packages.
