Application Development with SAPInternal reflection

• SAP recognised that customers were asking more than only ERP and dull GUI screens that nobody seemed to like anymore.

• SAP recognised that customers were looking for application platforms based upon open standards; applications that could easily interoperate with other applications within the company and with external systems.

• SAP recognised that Java and .Net were strong development languages highly adopted by the development community.

• SAP recognised that Service Oriented Architectures would be the next hype in techno land.

Service Oriented Architecture: a new hype?!

SOA

SOA is the new Architecture for everyone It is not invented by SAP

Some SOA misconception

• SOA is a new technology

• SOA is a marketing term

• Webservices = SOA

• Everything should be a webservice

• The more webservices, the better

• It is not possible to start with small projects

• SOA is still immature

The term “SOA” in wikipedia

• Service Oriented Architecture (SOA) is an architectural style that guides all aspects of creating and using business processes, packaged as services, throughout their lifecycle, as well as defining and provisioning the IT infrastructure that allows different applications to exchange data and participate in business processes regardless of the operating systems or programming languages underlying those applications. SOA represents a model in which functionality is decomposed into small, distinct units (services), which can be distributed over a network and can be combined together and reused to create business applications. These services communicate with each other by passing data from one service to another, or by coordinating an activity between one or more services.

1. SOA is an architectural model, not a technology

2. Enterprise Service Bus (ESB)

3. Services are often executed as Web Services

Lego and SOA

Web Services:

• Act as a blackbox with obligatory input and a fixedresult

• Can be published and called based on open technology standards (HTTP, XML)

• Works in synchronous and asynchronous scenarios

• A Web Service allows simple communication between different systems since it is using simple text messages in stead of complex and costly to maintain RPC.

What is a Service

Definition :

“A callable software component that is self-contained and self-describing and that is accessed via the exchange of messages. A service has a clearly defined interface.”

Stand aloneNo guarantee

No Governance

What is an Enterprise service?

Definition :

“An Enterprise Service is a service with the SAPBusiness logic!”

Common Data/Information

An Application Platform is an out-of-the-box integrated suite of common infrastructure services to build, integrate and run applications.

Netweaver History

• SAP NetWeaver™ technology platform is an integration, application and business process platform which helps with: – Reducing the total cost of ownership– Facilitating integration and orchestrate Information, People and

processes across departments and technologies.• SAP NetWeaver is the technical basis for mySAP™ Business Suite

and SAP® xApps™ and is a Webservices-based platform

SAP’s core business used to beproviding best practice functionality for different business areas

And revolutionised its business suites by making functionality available as enterprise services.

With NetWeaver 2004S, SAP has realised : A fully integrated and SOA based Application Platform supported by a rich repository of out-of-the-box application services.

SAP has transformed its SAP proprietary Basis Platform into an Application Platform “NetWeaver”

IT challenges are considerable

• Enable service of existing legacy-applications is difficult

• Spaghetti of GUI, workflow, business logic and data

• Parallel use of new services and old transactions

• How define services (granularity)? • ESB is complex technology• Qualified competencies needed• ESB is very flexible: ‘create your

future mess…’

In practice

Its not simple:• A lot of acronymes, standards and technologies• Every vendor has SOA solutions• How to justify IT-investments with the business?• Is there a shot-term business value?• Where to start?

Technical issues (to expect!)

• Security• Performance• maintenance• ….

CE the toolbox for Composites development

• The Composition Environment (CE) is an application development environment for building composites.

• Composites are a new type of applications and are characterised by– Process driven through Guided Procedures– An adapted user friendly UI for executing a task– Invoking web services from the ERP backend

• Composites are build using Visual Tools (Visual Composer, Adobe Forms) and Java for the more complex UI.

• Simple composites can be assembled without any coding.With CE Java developers can automate processes across departments and across companies. Simple composites can be assembled by Bus. Analysts.

Master data is crucial to the business……but every department has a different version of it.

Master data is data about customers, products, suppliers, etc.

Business partner data introduces yet another version of data.

Inaccurate data leads to $ 30+ billion cost on supply chains.

Why do we need Master Data Management?

• To ensure optimized processes with data that is always up-to-date (real-time enterprise)

• To reduce the costs of maintaining and correcting data through standardized processes and central management

• As a prerequisite for service oriented architectures– With true master data, Web services and the related business

processes will become more accurate, timely, and efficient, leading to improved ROI on existing investments as well as improved business intelligence.”

– Forrester Research, 2006

Role of MDM in the transition towards SOA

• Enabling the reuse of functions as enterprise services in order to eliminate functional redundancy, which is one of the main objectives of SOA, is only possible if these functions are based on a single source of master data.

• Process steps can only be combined if the same master data structure is used.

• Moving master data into a MDM system helps decouple data, processes and user interface even further. Current systems don’t effect a clear separation of data, processes and UI (e.g. data is used for process management, or the UI affects the master data structure).

• The ideal level of separation is achieved by having clearly defined boundaries between mater data management, enterprise services (process) and the user interface.
