Enterprise Services Repository is ...

“… the central repository where service interfaces

and enterprise services are modelled and their

metadata is stored.”

Services Registry - UDDI V3 compliant

registry that supports publishing,

classifying and discovering services

repository of all service objects for

5. Summary


Service Simplification Adaptation – Motivation

Enterprise services are

■ designed and implemented for the most common standard use cases

■ not aware of the context of their usage (e.g. UI technologies).

Therefore Enterprise Services having a need

■ for adapting and transforming the service signatures depending on the

domain of their usage.

Service Simplification Service Composition – Use Cases

Provide a simplified (adapted) service for large backend service

■ Reduce the interface by hiding fields

■ Structural changes

■ Data transformation

■ Combination of values

■ Renaming of fields

Provide a single service based on the output of multiple backend services

■ Services must be called in a specific sequence…

■ …with a specific data flow between them

■ Conditional and iterative processing of the data in scope

Assign default values to specific (input/output) fields

Key Capabilities supporting

service simplification:

Enterprise Services

Repository:

Design simplified service interface

based on Global Data Types

(GDT’s)

Connectivity

Allows usage and translation of

different communication

protocols, data formats and

interfaces

Mapping:

Use of standard mapping

functionality


Use Case - Supporting Composite Applications Synch/Asynch bridge

Benefits:

Flexible integration with

different backend

environments that

provide synchronous

OR asynchronous

message interfaces


Service simplification via SAP NetWeaver PI Advantages

Advantages:

Allows integration of systems and translation using…

– Different communication protocols (not restricted to Web Services)

– Different data formats and interfaces

Allows service simplification of multiple backend interfaces / services inclusive

– asynch / synch bridge

– synch / asynch bridge

Reuse of simplified services for system-to-system interaction also in an asynchronous scenario

Reuse interface mapping of simplified services

Optimized load distribution between SAP NetWeaver CE and PI

5. Summary


Introducing the exercise

GOAL:

This exercise shows how a SAP Enterprise Service is simplified with the help of

the Service Composer. Consequently the simplified service is integrated into the

SAP NetWeaver BPM scenario (already available from exercise 1 & 2).

Service Mocking:

Additionally we will use the new

feature service mocking to test

and accomplish this service

simplification example.


Introducing the exercise Simplify the SAP Enterprise Service

■ Open the properties of the

simplified service

■ Define which fields of the

Enterprise Service have to be

mapped to which fields of the

simplified service

■ If needed: define fixed values for

corresponding fields of simplified

service


Introducing the Exercise Service Mocking

■ Open context menu and choose

“Replace with Mock Service” ■ If needed, define fixed values


Agenda

5. Summary


Summary

Service Simplification offers the possibility

to abstract complex services and make

them easier consumable by the composite.

Service Simplification is able to transform

services and its parameters in a fitting

structure and allows the definition of fixed

values.
