• What is the cause and solution for SAP error message /IWBEP/SBOD002 - Base type name '&1' is not unique ?

  The SAP error message /IWBEP/SBOD002 Base type name '&1' is not unique typically occurs in the context of SAP Gateway and OData services. This error indicates that there is a conflict with the naming of base types in your OData service definition. Specifically, it means that the base type name you are trying to use is already defined elsewhere in the system, leading to ambiguity.
  Cause:
  
  Duplicate Base Type Names: The most common cause of this error is that there are multiple definitions of the same base type name in the OData service or in the underlying data model.
  Namespace Issues: If you are using different namespaces, it is possible that the same base type name exists in different namespaces, causing a conflict.
  Model Changes: Changes made to the data model or service definitions that have not been properly activated or have conflicting definitions can also lead to this error.
  
  Solution:
  
  Check for Duplicates: Review the OData service definitions and check for any duplicate base type names. Ensure that each base type name is unique within the context of your service.
  Use Unique Namespaces: If you are defining custom base types, consider using unique namespaces to avoid conflicts with standard or other custom types.
  Activate Changes: If you have made changes to the data model or service definitions, ensure that all changes are activated. You can do this by navigating to the relevant transaction (e.g., SE80 or SEGW) and activating the service.
  Clear Cache: Sometimes, clearing the cache can help resolve issues related to outdated definitions. You can do this by using transaction code /IWFND/CACHE to clear the OData service cache.
  Check Service Metadata: Use the service metadata URL (e.g., /sap/opu/odata/sap/<service_name>/$metadata) to inspect the definitions and ensure that there are no conflicts.
