  The SAP error message NSDM_MIG_CONTROL025 indicates that there is an issue with creating MKPF (Material Document Header) groups because the grouping process has already been triggered. This typically occurs during the migration or data transfer processes in SAP, particularly when dealing with material documents.
  Cause:
  The error is usually caused by one of the following reasons:
