This error indicates that a required field (denoted by &2) is empty for a specific line (denoted by &1) in the data being processed.
  Cause:

  Update Data: If you find that the required field is indeed empty, update the data to include the necessary information and reprocess the data.
  Debugging: If the issue persists, consider using debugging tools in SAP to trace the data flow and identify where the data is being lost or not populated.
