I want to show you the different steps to execute when you implement a service interface in SAP NetWeaver Process Integration 7.1. In this particular example we will follow one of the service interface patterns introduced in this new version (the TU&C/C pattern). I won’t cover here the modeling and service provisioning and consumption proxies.

This blog also represents a summary document is supposed to link many other documents (referenced here) that will finally give a comprehensive idea of this topic:

Before showing the steps proposed, I want to briefly introduce what could be the different approaches regarding process integration implementation.

  • Inside-Out:
    -Development either already exists or starts in the application systems. You normally reuse existing WSDLs, BAPIs, data base tables, etc. Business Model is already defined; process integration can usually be seen as systems synchronization.
    -The configuration is performed also in the application systems.
  • Outside-In (also referred as “Central”):
    -Development starts in the Enterprise Services Builder. Precisely in Enterprise Services Repository. You start by modeling the integration, later the SAP Application Systems are able to access and automatically create proxies for the service interface operations. Other technical integration methods are also available.
    -The configuration is carried out centrally using the Integration Directory (optional).


Here I describe the list of steps required to implement a service interface. Consider that in order to see the recordings, you need the free SAP Tutor personal player. It can be downloaded directly from the service marketplace (

Create Basic Component in the ES Repository

First of all let’s take a very brief introduction to the development environment and an introduction to the topic:

Create Service Interfaces

Supposing you already did the previous modeling, you should now go ahead and create you service interfaces and operations:

Create the Operations Mappings

The operation mapping replaces the interface mapping, and you have to create one for each operation of the service interface:

Update SLD

After the design time activities have finished, it is time to update or confirm the configuration of the SLD objects:

Check Business Systems configuration in the Integration Directory

Before working on the specific configuration, you have to make sure the systems are properly configured in the Integration directory:

Perform Configuration in the Integration Directory

Finally, you can go ahead and configure your integration:

Additional Steps for ABAP environments

After PI steps are done, it is time logon the back-end systems and create the proxies and consumer or provider methods, which are performed using wizards in a similar fashion than before using transaction SPROXY or the ABAP Object Browser (SE80).
