  Cause:
  
  Database Locking: The table may be locked by another transaction, preventing the deletion of the data.

  Authorization Issues: The user executing the deletion may not have the necessary authorizations to perform the delete operation.
  Data Integrity Issues: There may be issues with the data integrity that prevent the deletion.
  Technical Issues: There could be underlying technical issues with the database or the SAP system itself.
