• What is the cause and solution for SAP error message /IWBEP/SBDM064 - Error: &1 with technical name '&2' already exists in base service ?

  The SAP error message /IWBEP/SBDM064 indicates that there is an attempt to create or register a service or entity that already exists in the base service. This typically occurs in the context of SAP Gateway and OData services, where entities or service definitions must be unique within a given service.
  Cause:
  
  Duplicate Entity or Service Definition: The error is primarily caused by trying to define an entity or service that has already been defined in the same service or data model.
  Incorrect Service Registration: If a service is being registered multiple times without proper checks, this error can occur.
  Transport Issues: If changes are transported from one system to another, and the same entity or service already exists in the target system, this error may arise.
  
  Solution:
  
  Check Existing Definitions: Review the existing service definitions in the SAP Gateway Service Builder (transaction code /IWBEP/SEGW). Look for the entity or service with the technical name specified in the error message (&2).
  Remove Duplicates: If you find that the entity or service already exists, you may need to either:
  
  Modify the existing entity/service instead of creating a new one.
  Delete the duplicate entry if it is not needed.
  
  
  Adjust Service Registration: Ensure that your service registration logic does not attempt to register the same service multiple times. This may involve adding checks before registration.
  Transport Management: If the issue is related to transport, ensure that the transport requests are correctly managed and that entities/services are not being duplicated during the transport process.
  Rebuild the Service: If necessary, you can try to rebuild the service by deleting the problematic entity/service and recreating it.
  
  Related Information:
