Check the sections below to know about software requirements, operations supported and constraints for SAP Gateway integration with GenIL, along with this the following topics are covered:


Make sure that the following system prerequisites are fulfilled:

  • You have an SAP Gateway Hub system where software component IW_FND 250 is deployed.

  • You should have the following software components deployed either on the SAP Gateway Hub system or on the SAP backend system:

    • IW_BEP 200

    • IW_GIL 100

    • WEBCUIF 7.0 SP03 and above

Operations Supported

The table lists all the operations supported for each type of GenIL node:

GenIL Node Type/Operations






Root Object

Access Object

Dependent Object


Not supported


The entities corresponding to the root and access objects are marked as sap:addressable = true and those corresponding to dependent objects are marked as sap:addessable = false. This means that the query on a dependent object can only be triggered via a navigation property of a root/access object.


At present the following constraints apply:

  • Currently, the CUD (Create, Update and Delete) operations are not supported on the related objects.

  • Filtering is supported only for those properties of an entity (corresponding to the root/access object) which has a similar named field in the attribute structure of the default query.

  • Dependent objects which are assigned as related objects to more than one root/access/dependent object in the GenIL model are not supported currently.
