• What is the cause and solution for SAP error message CFD_REGISTRY_CHECK064 - Entity Type &1 referenced in differently mapped Entity Sets ?

  The SAP error message CFD_REGISTRY_CHECK064 indicates that there is a mismatch in the mapping of entity types to entity sets in your SAP system. This typically occurs in the context of SAP Gateway or OData services, where entity types are defined and mapped to specific entity sets. The error suggests that the same entity type is being referenced in multiple entity sets with different mappings, which can lead to inconsistencies and confusion in data retrieval.
  Cause:
  
  Multiple Mappings: The same entity type is mapped to different entity sets in the service definition, which is not allowed.
  Inconsistent Metadata: There may be inconsistencies in the metadata definitions for the OData service, leading to conflicts in how entity types are referenced.
  Service Registration Issues: The service might not be properly registered or activated, causing the system to misinterpret the mappings.
  
  Solution:
  
  
  Review Entity Mappings: Check the service definition in the SAP Gateway Service Builder (transaction code SEGW) to ensure that each entity type is mapped to only one entity set. If an entity type is referenced in multiple entity sets, you will need to resolve this by either consolidating the mappings or creating separate entity types for each entity set.
  
  
  Update Metadata: If you have made changes to the entity types or entity sets, ensure that the metadata is updated. You can regenerate the metadata by right-clicking on the service in the Service Builder and selecting "Generate Runtime Objects."
  
  
  Check Service Registration: Ensure that the OData service is properly registered and activated in the SAP Gateway. You can do this using transaction code /IWFND/MAINT_SERVICE. Check if the service is listed and active.
  
  
  Clear Cache: Sometimes, caching issues can lead to this error. Clear the cache of the OData service using transaction code /IWFND/CACHE or by using the "Clear Cache" option in the SAP Gateway Client.
  
  
  Debugging: If the issue persists, consider debugging the service to identify where the mapping conflict is occurring. This may involve checking the implementation of the service and the associated data model.
