  The SAP error message /IWBEP/CM_CP163 indicates that there is an issue with the HTTP Client Factory in the context of the SAP Gateway or OData services. Specifically, the message states that "Object ref. attributes are not supported," which typically means that there is a problem with the way the attributes of an object reference are being handled in the OData service.
  Cause:
  
  Unsupported Attributes: The error usually arises when the OData service is trying to access or manipulate attributes of an object reference that are not supported or not properly defined in the service metadata.
  Incorrect Data Model: There may be inconsistencies or errors in the data model or the way the entity types and their relationships are defined in the OData service.
  Service Implementation Issues: The implementation of the OData service might be trying to access attributes that are not part of the entity or are not exposed in the service definition.
  Version Mismatch: There could be a mismatch between the versions of the SAP Gateway and the backend system, leading to compatibility issues.
  
  Solution:
  
  Check Metadata: Review the OData service metadata to ensure that all attributes are correctly defined and supported. You can access the metadata by appending $metadata to the service URL.
  Review Service Implementation: Check the implementation of the OData service in the backend (ABAP code) to ensure that it is correctly handling the object references and their attributes.
  Update Service: If there are changes in the data model, regenerate the OData service to ensure that the latest definitions are reflected.
  Debugging: Use debugging tools to trace the execution of the OData service and identify where the error occurs. This can help pinpoint the exact attribute or object reference causing the issue.
  Check for Notes: Look for SAP Notes or updates related to the specific error message or the components involved. Sometimes, SAP releases patches or notes that address known issues.
  Consult Documentation: Review the SAP Gateway and OData documentation for any specific guidelines or limitations regarding object references and attributes.
