• What is the cause and solution for SAP error message /IWBEP/CM_MGW_RT112 - Property name: '&1' ABAP field name '&2' already exists ?

  The SAP error message /IWBEP/CM_MGW_RT112 indicates that there is a conflict with property names in your OData service. Specifically, it means that a property name (represented by &1) is already associated with an ABAP field name (represented by &2) in the context of the OData model.
  Cause:
  This error typically occurs when:
  
  There are duplicate property names defined in the OData service metadata.
  The same property is being defined multiple times in the service implementation or in the data model.
  There might be a mismatch or conflict in the naming conventions used in the ABAP backend and the OData service.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check for Duplicates:
  
  Review the OData service definition in the SAP Gateway Service Builder (transaction code SEGW).
  Look for duplicate property names in the entity types. Ensure that each property name is unique within its entity.
  
  
  
  Adjust Property Names:
  
  If you find duplicate property names, rename them to ensure uniqueness. This may involve changing the property name in the ABAP structure or the OData model.
  
  
  
  Regenerate the Service:
  
  After making changes, regenerate the OData service. You can do this by right-clicking on the service in the Service Builder and selecting "Generate".
  
  
  
  Check Data Model:
  
  Ensure that the underlying ABAP structures or tables do not have conflicting field names that could be causing the issue.
  
  
  
  Clear Cache:
  
  Sometimes, caching issues can cause problems. Clear the cache for the OData service using transaction /IWFND/CACHE_CLEANUP.
  
  
  
  Test the Service:
  
  After making the necessary changes, test the OData service again to ensure that the error has been resolved.

  Debugging:
  
  If the issue persists, consider debugging the service implementation to trace where the property names are being defined and identify any potential conflicts.
  
  
  
  By following these steps, you should be able to resolve the error and ensure that your OData service functions correctly.
