• What is the cause and solution for SAP error message /IWBEP/SBOD101 - Entity Type name '&1' is not unique ?

  The SAP error message /IWBEP/SBOD101 Entity Type name '&1' is not unique typically occurs in the context of SAP Gateway and OData services. This error indicates that there are multiple entity types defined with the same name in the service metadata, which violates the uniqueness requirement for entity type names.
  Cause:
  
  Duplicate Entity Type Definitions: The most common cause of this error is that there are two or more entity types defined with the same name in the OData service.
  Incorrect Model Configuration: If the data model is not configured correctly, it can lead to the generation of duplicate entity types.
  Multiple Data Sources: If the OData service is pulling data from multiple sources that define the same entity type, this can also lead to conflicts.
  
  Solution:
  
  
  Check Entity Type Definitions:
  
  Go to the service definition in the SAP Gateway Service Builder (transaction code SEGW).
  Review the entity types defined in your model and ensure that each entity type has a unique name.
  
  
  
  Rename Duplicate Entity Types:
  
  If you find duplicate entity types, rename them to ensure uniqueness. This may involve changing the name in the service definition and updating any references to that entity type in your code.
  
  
  
  Regenerate the Service:
  
  After making changes to the entity types, regenerate the service. This can be done in the Service Builder by selecting the service and choosing the "Generate" option.
  
  
  
  Check for Inheritance:
  
  If you are using inheritance in your entity types, ensure that the base entity type is not causing conflicts with derived types.
  
  
  
  Clear Cache:
  
  Sometimes, caching issues can cause this error to persist. Clear the cache of the OData service using transaction code /IWFND/MAINT_SERVICE and then re-test the service.
  
  
  
  Check for Multiple Versions:
  
  If you have multiple versions of the same service, ensure that they are not conflicting with each other.

  Documentation: Refer to SAP Help documentation for OData services and the SAP Gateway for more detailed information on service definitions and entity types.
  
  
  Debugging: If the issue persists, consider using debugging tools to trace the service execution and identify where the duplicate entity types are being generated.
  
  
  By following these steps, you should be able to resolve the /IWBEP/SBOD101 error and ensure that your OData service functions correctly.
