  The SAP error message /IWBEP/SBUIOD063 Enter the Entity Type name for Principal Entity typically occurs in the context of SAP Gateway or OData services when there is an issue with the configuration of the OData service, particularly related to the entity types defined in the service.
  Cause:
  
  Missing Entity Type: The error indicates that the system expects an entity type name to be provided, but it is either missing or incorrectly specified.
  Incorrect Configuration: The OData service might not be properly configured, leading to the system not recognizing the principal entity.
  Model Issues: There could be issues with the data model or the metadata of the OData service, such as missing or incorrectly defined entity sets or types.
  Service Activation: The OData service may not be activated properly in the SAP Gateway.
  
  Solution:
  
  
  Check Entity Type Definition:
