  The table may contain critical configuration or master data that should be preserved.

  Solution:
  
  
  Check Table Status: Verify the status of the table in the SAP system. You can do this by checking the table's attributes in the Data Dictionary (transaction SE11). Look for any flags or settings that indicate it is marked as "not use."

  Consult Documentation: Refer to the documentation for the specific migration tool or process you are using. There may be guidelines on how to handle tables marked as "not use."
  
  
  Contact SAP Support: If you are unsure about the implications of deleting data from this table or if you believe it should not be marked as "not use," consider reaching out to SAP support for guidance.
