Content Organization in SAP PI for Interface Designers

0

This article is part of our Integration Cookbook.

ICB2

To design interfaces for SAP PI, you need to consider the following aspects and follow the principles regarding Software Components:

  • Separate Sender Application/System from Receiver
  • Mappings are always created in the Receiver (Target) Software Component
    • Generic Mapping functions can be created in a central, reusable Software Component
      • E.g. _MAPPING 1.0 of <vendor.com>
      • This Software component can be used as an underlying SWC in other components
  • BPM processes are ideally “speaking” the language of the sender OR receiver – sometimes they have their own set of interfaces. Based on that, the content is created on sender, receiver or a BPM-specific SWC.
  • Always use a /BPM namespace to indicate the usage

ICB3

  • Make Use of Process Integration Scenarios (swimlanes) to design your interfaces (and automatically document them)
    • They are located in a generic (central) software component: _INTEGRATION_SCENARIOS 1.0 of <vendor.com>
      Choose Software Components with internal Actions for Business Systems and
      Templates with local Actions for Business Component (also BPM Process)
  • The Vendor is always the creator of the Integration Content
