• What is the cause and solution for SAP error message /UI2/PB_V06002 - Parameter sourceId for FunctionImort are missing ?

  The SAP error message /UI2/PB_V06002 Parameter sourceId for FunctionImport are missing typically occurs in the context of SAP Fiori applications or OData services when a required parameter is not being passed correctly to a function import in an OData service.
  Cause:
  
  Missing Parameter: The error indicates that the sourceId parameter, which is expected by the function import, is not being provided in the request.
  Incorrect Configuration: There may be an issue with the configuration of the OData service or the Fiori application that is calling the service.
  Frontend Issues: The frontend application (like a Fiori app) may not be correctly set up to send the required parameters.
  Backend Issues: The backend service might not be properly defined to handle the function import or might have been changed without updating the frontend.
  
  Solution:
  
  
  Check the OData Service:
  
  Verify that the OData service is correctly defined and that the function import is set up to accept the sourceId parameter.
  Use transaction code /IWFND/MAINT_SERVICE to check the service registration and ensure it is active.
  
  
  
  Review the Fiori Application:
  
  Check the Fiori application code to ensure that the sourceId parameter is being passed correctly when calling the function import.
  If you are using a custom Fiori app, ensure that the binding and parameters are correctly set in the controller.
  
  
  
  Debugging:
  
  Use the browser's developer tools (F12) to inspect the network requests being made by the Fiori application. Look for the request to the OData service and check if the sourceId parameter is included.
  If it is missing, trace back to the part of the code where the function import is called and ensure that the parameter is being set.
  
  
  
  Check for Updates:
  
  If the application or service has been recently updated, ensure that all changes are compatible and that the frontend is aware of the latest backend definitions.
  
  
  
  Consult Documentation:
  
  Review the SAP documentation for the specific OData service and function import to ensure that you are using it correctly.
  
  
  
  Testing:
  
  If possible, test the function import directly using tools like Postman or the SAP Gateway Client (transaction /IWFND/GW_CLIENT) to see if the issue persists when calling the service directly.
