• What is the cause and solution for SAP error message /IWFND/CM_COS147 - External error not triggered on SAP Gateway but for example on a client ?

  The SAP error message /IWFND/CM_COS147 typically indicates that an external error was not triggered on the SAP Gateway but was instead encountered on the client side. This can occur in various scenarios, particularly when dealing with OData services in SAP Gateway.
  Cause:
  
  Client-Side Issues: The error may arise from the client application (like SAP Fiori or any other front-end application) not handling the response correctly or not triggering the expected error handling mechanism.
  Service Configuration: There might be issues with the OData service configuration, such as incorrect service registration or missing metadata.
  Network Issues: Connectivity problems between the client and the SAP Gateway can lead to unexpected behavior.
  Authorization Issues: The user may not have the necessary authorizations to access the service or perform the requested operation.
  Data Issues: Invalid or unexpected data being sent from the client to the server can also lead to errors that are not properly communicated back to the client.
  
  Solution:
  
  Check Client-Side Logic: Review the client-side code to ensure that it is correctly handling responses and errors from the OData service.
  Service Registration: Verify that the OData service is correctly registered in the SAP Gateway. You can do this using transaction code /IWFND/MAINT_SERVICE.
  Test the Service: Use the SAP Gateway Client (transaction /IWFND/GW_CLIENT) to test the OData service directly. This can help identify if the issue is with the service itself or the client.
  Check Authorizations: Ensure that the user has the necessary authorizations to access the OData service. You can use transaction code SU53 to analyze authorization issues.
  Review Network Configuration: Check for any network issues that might be affecting communication between the client and the SAP Gateway.
  Debugging: If the issue persists, consider debugging the OData service to trace where the error occurs and why it is not being communicated back to the client.
