Working with Tabstrip in Webdynpro for ABAP

Applies to: SAP ECC 6.0 (Release 700, SP 12). For more information, visit the Web Dynpro ABAP homepage..

Summary This tutorial explains about Step-By-Step procedure for creating a Tabstrip in Webdynpro ABAP. It makes use of a number of UI elements as well. We will also see how to clear the selection screen context and how to call a POPUP window.

Description The Tabstrip UI element allows the display of a tab page. The user can toggle between several tab pages by selecting a specific tab. The same window is shared by all tab pages and used for displaying the content. The user can display the content of a tab by selecting a tab title.

Scenario:

To create a Webdynpro application with a Tab strip.

UI Elements on the output screen: Parameter: Airline Code: SFLIGHT-CARRID Button: “SUBMIT”. Tables in Tabstrip: Displays the list of all flights and Flight schedules in two different tabs based on the input given by user on Screen. And also displays a popup window with a message if no flight detail exists with given input. Snap Shot of output Screen:



Create Webdynpro Component

Go to transaction SE80. Select “Webdynpro Comp. /Intf” from the list. Create a new Webdynpro component by the name ZWDA_TABSTRIP.

Creating context in Component Controller

In component Controller create the nodes and attributes. We are taking Airline code i.e. CARRID as input and displaying the list of all flights (SFLIGHT) and Flight schedules (SPFLI) as output. So create these attributes in the context of component controller. Right click on the context tab create node.

For CARRID create node as shown below and select “Add Attribute from structure” and create attribute to the node. Make sure that the cardinality is 1..1 as it is the input field.



Select the fields you want to display from the table SFLIGHT using “Add attribute from structure” button.



Similarly create the remaining two nodes SFLIGHT and SPFLI with corresponding attributes. Make the cardinality as 0..N for these two nodes. Finally the context in the component controller looks like the below figure.

Design View Create a view for the selection. Activate the component at this point of time. On the Context Tab, drag the nodes from the Component Controller context and drop it onto the Main

View Context.

Define the layout of the view. Create a label to the input field. Right click on ROOTUIELEMENTCONTAINER and insert element as shown below.



Create a label by specifying the type as label.

Create the INPUT field and set the Property as shown in the figure. Click on the “value” field and select the Carrid node from the context Main view. This will be input field for the application.

Create one Button and if you click this button the flight details will be display in the table.

In button properties give action as SELECTION.



If you give the property as SELECTION, then one event handler will generate for this button with name ONACTIONSELECTION. In this handler you need to write the code that you want to execute when ever button is pressed.

Creation of TABSRIP. To create Tabstrip insert Tabstrip element in your layout, further to create n no. of tabs, right click on the Tabstrip and insert tab as shown below.

In the current application insert two tabs.



Note: In each tab only one element can be created. The UI Element ‘transparent container’ can be used to have multiple elements in a single tab.

We need to add elements to tab separately. In the first tab add a table with Sflight node details. And in the second tab add a table with Spfli node details.



After adding table element to the tab, Bind the Table with the corresponding Nodes we created in the Context Component. The same is shown below.

Select the context and we get the nodes in the context of the view. Select the Sflight node and we get the below details.



After binding the table this is the screen with table values binded with context.

Similarly create a table and bind the values of “Spfli” node for the second tab. After all it looks like the below screen.



Implementation of the methods

Write the code you want to execute in ONACTIONSELECTION method of the Button. Go to Wizard and select the radio button “READ Context” and insert the nodes names “CARRID”. Press the OK button. Now the Wizard generates the code to access the node Carrid. Similarly do for the remaining two nodes i.e. SFLIFGT and SPFLI.

We are reading the context of Node CARRID. Similarly get the nodes of SFLIGHT and SPFIL from context using via lead selection.

Fetch the data from Sflight and Spfli into tables based on the input field Carrid. See the below code for more information.

Embedding view to window

In window embed the view MAINVIEW.



After embedding the screen would be



Create a WebDynpro Application

Create WebDynpro application. And save it.

Activate the WebDynpro component.

Test WebDynpro component.

Output 1: If an entries exits for the selection criteria.

Select the value from the search help and click on Display button. Data for selected values will be displayed in Tabstrip element like below.

Values in the first tab Sflight Details.



Values in the second tab Spfli Details.

OUTPUT 2: If there doesn’t exits entries for the selection criteria.

Give any Airline code as an input which doesn’t have entries in Sflight and Spfli.



This is the final Output.
