  Update SAP System: Ensure that your SAP system is up to date with the latest support packages and patches, as these may contain fixes for known bugs related to locking.
  Database Consistency Check: Perform a consistency check on the database to ensure there are no underlying issues affecting the locking mechanism.
  Contact SAP Support: If the issue persists, it may be necessary to contact SAP support for further assistance, especially if it appears to be a bug or a more complex issue.
