Designing A2A Integration 

Use

Using this process, you:

●      Import the required ESR content (process integration content) and the adapter metadata to the Enterprise Services Repository (ESR)

●      Model the process integration scenarios and the required design objects in the Enterprise Services Repository and then activate the objects

●      Use the design objects to generate proxies in the back-end systems

●      Implement the application code in the back-end systems

Procedure

Import Process Integration Content

In this step you import the required ESR content to the Enterprise Services Repository.

See: SAP Note 836200

See: Transporting ESR Objects.

Import Adapter Metadata

In this step you import the adapter metadata for the newly developed adapters to the Enterprise Services Repository. This step is required so that you can then configure the adapters.

See: Loading Adapter Metadata

Model Process Integration Scenarios

In this step you model the process integration scenario for the business process.

The process integration scenario is the starting point for developing interfaces and mappings.

See: Granularity of Process Integration Scenarios

Design Interfaces

In this step you design the interfaces for defining the content of the exchanged messages and the type of communication.

See: Designing Interfaces and Proxy Generation

Design Mappings

In this step you design mappings for mapping message structures to one another.

See: Designing a Mapping

Model Integration Processes

If stateful message processing is required on the Integration Server, in this step you define the required integration processes.

See: Integration Processes (ccBPM)

Activate Change Lists

In this step you activate the design objects so that you can then configure them.

See: Change Lists.

Generate Proxies

In this step you generate the executable proxies from the interfaces you designed earlier.

See: Designing Interfaces and Proxy Generation

Implement Code

In this step, based on the proxies you generated, you implement the application code for connecting applications on the SAP Web AS to the Integration Server.
