• What is the cause and solution for SAP error message /IWFND/CM_CONSUMER065 - Outbound mapper method: mapQRCResult ?

  The SAP error message /IWFND/CM_CONSUMER065 typically relates to issues encountered in the OData service when mapping the results from a query. The specific mention of "Outbound mapper method: mapQRCResult" indicates that the error occurred during the mapping of the query result to the response format expected by the consumer.
  Cause:
  
  
  Data Mapping Issues: The error can occur if there are discrepancies between the data structure defined in the OData service and the actual data being returned from the backend. This could be due to missing fields, incorrect data types, or unexpected null values.
  
  
  Service Configuration: If the OData service is not properly configured, it may lead to issues in how the data is being processed and returned.
  
  
  Authorization Issues: Sometimes, the error can arise if the user does not have the necessary authorizations to access certain fields or entities in the OData service.
  
  
  Backend Errors: If there are issues in the backend system (like ABAP code errors, database issues, etc.), it can lead to problems in the data being returned.
  
  
  Versioning Issues: If there are changes in the OData service or the underlying data model that are not reflected in the consumer application, it can lead to mapping errors.
  
  
  Solution:
  
  
  Check Data Structure: Verify that the data structure defined in the OData service matches the data being returned. Ensure that all required fields are present and that data types are correct.
  
  
  Review Service Configuration: Check the configuration of the OData service in the SAP Gateway. Ensure that the service is activated and that all necessary entities and properties are correctly defined.
  
  
  Authorization Checks: Ensure that the user has the necessary authorizations to access the OData service and the specific fields being queried.
  
  
  Debugging: Use transaction /IWFND/ERROR_LOG to check for detailed error logs. You can also debug the OData service to see where the mapping is failing.
  
  
  Check Backend Logic: If the OData service is calling backend logic (like ABAP function modules or classes), ensure that there are no errors in that logic. Check for any exceptions that might be raised.
  
  
  Update Consumer Application: If there have been changes to the OData service, ensure that the consumer application is updated to reflect those changes.
  
  
  Testing: Use tools like Postman or the SAP Gateway Client to test the OData service independently to see if the issue persists outside of the consumer application.
