Configuration of Business Systems with Integration Engine 

The Integration Engine is the runtime environment of SAP NetWeaver usage type Process Integration. It controls the messaging process (receiving, processing, and forwarding) to and from the central Integration Server.

Before configuring business systems with an Integration Engine, ensure the following:

●      For business systems based on SAP Web Application Server (AS) 6.20:

You have installed the XI Add-On in each of these business systems as described in the Installation Guide – SAP Exchange Infrastructure 2.0.

Use SAP Web AS 6.20 kernel patch level 1253 or higher if you want to generate new ABAP proxies on your business systems based on SAP Web AS 6.20.

●      The business systems and your central Integration Server are maintained in the System Landscape Directory (SLD).

For the central Integration Server, the following Common Information Model (CIM) objects must have been instantiated in the SLD:

●      Choose Technical Systems to describe your Integration Server technically.

This is not necessary if your Integration Server is configured as a data supplier for the SLD.

●      Choose Business Systems to define the business system with the role of an Integration Engine and define the corresponding Integration Server.
