  Cause:
  
  Entity Set Configuration: The entity set specified in the error message may not be properly defined in the OData service. This could be due to a missing or incorrectly configured entity type in the service's metadata.
  Service Registration: The OData service may not be correctly registered or activated in the SAP Gateway.

  Solution:
