This locking mechanism is in place to prevent data inconsistencies and ensure that multiple users do not make conflicting changes to the same inspection lot simultaneously.
  Causes:

  Release Locks: If you have the necessary authorizations, you can manually release the lock from transaction SM12. However, be cautious when doing this, as it may lead to data inconsistencies if the other user is still processing the lot.
  Check Background Jobs: If background jobs are causing the lock, you may need to wait for them to complete or check if they can be rescheduled.
  System Monitoring: Monitor the system for any performance issues or deadlocks that may be causing prolonged locks. This may involve checking system logs or using transaction SM21 for system log analysis.
  Consult Basis Team: If the issue persists, it may be necessary to involve your SAP Basis team to investigate further, especially if there are underlying system issues.
