• What is the cause and solution for SAP error message /IWBEP/SBOD104 - Property name '&1&2&3' not unique ?

  The SAP error message /IWBEP/SBOD104 Property name '&1&2&3' not unique typically occurs in the context of SAP Gateway and OData services. This error indicates that there is a conflict with property names in the data model, where the specified property name is not unique within the context of the service or entity type.
  Cause:
  
  
  Duplicate Property Names: The error is primarily caused by having multiple properties with the same name in the same entity type or in the same context. This can happen if:
  
  You have defined the same property in multiple places (e.g., in different structures or entities).
  There are naming conflicts due to inheritance or composition in your data model.
  
  
  
  Incorrect Metadata Definition: If the metadata definition for your OData service is not correctly set up, it can lead to ambiguities in property names.
  
  
  Changes in Data Model: If there have been recent changes to the data model (like adding new fields or modifying existing ones) without proper adjustments in the OData service, it can lead to this error.
  
  
  Solution:
  
  
  Check for Duplicates: Review the entity types and structures in your data model to ensure that there are no duplicate property names. You can do this by:
  
  Navigating to the Data Model in the SAP Gateway Service Builder (transaction code SEGW).
  Checking the properties of each entity type to ensure uniqueness.
  
  
  
  Rename Properties: If you find duplicate property names, consider renaming them to ensure that each property has a unique name within its context.
  
  
  Regenerate the Service: After making changes to the data model, regenerate the OData service:
  
  In the Service Builder, right-click on the service and select "Generate Runtime Objects."
  This will update the metadata and ensure that the changes are reflected in the OData service.
  
  
  
  Check Metadata: Use the OData service's metadata URL (usually something like /sap/opu/odata/sap/<service_name>/$metadata) to inspect the generated metadata and confirm that property names are unique.
  
  
  Clear Cache: Sometimes, caching issues can cause this error. Clear the cache of the OData service using transaction code /IWFND/CACHE_CLEANUP.
