Application Development with SAP
Internal 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
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.”
Web Services:
• Act as a blackbox with obligatory input and a fixed
result
• 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.
Stand alone

No Governance
What is an Enterprise service?
Definition :
“An Enterprise Service is a service with the SAP
Business logic!”
eSOA is SAP specific

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

SAP Basis / ABAP WB
SAP’s core business used to be
providing 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.

IT challenges are considerable
• Enable service of existing legacyapplications 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…’

NWDS the toolbox for custom development
• NetWeaver Developer Studio (NWDS) is a development
environment similar to MS Visual Studio or IBM’s Rational
Application Developer.
• NWDS is build on Eclipse – an open source integrated
development environment and a standard in the Java
community.
• With NWDS developers can develop Java and J2EE
applications.
• NWDS has a number of plugins for creating:

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 upto-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.
