• What is the cause and solution for SAP error message QI183 - Inspection lot is locked by another user ?

  The SAP error message QI183, which states "Inspection lot is locked by another user," typically occurs when a user attempts to access or modify an inspection lot that is currently being processed or edited by another user. 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:
  
  Concurrent Access: Another user is currently working on the same inspection lot, which locks it for editing.
  Long-running Transactions: A user may have opened the inspection lot and is taking a long time to complete their transaction, causing the lock to persist.
  System Errors: Occasionally, system errors or crashes can leave locks in place even after the user has exited the transaction.
  Background Jobs: If a background job is processing the inspection lot, it may also cause a lock.
  
  Solutions:
  
  Wait and Retry: If the inspection lot is locked by another user, the simplest solution is to wait for that user to complete their transaction and then try again.
  Identify the Lock: Use transaction code SM12 to check for locks. You can see which user is holding the lock on the inspection lot. If necessary, you can contact that user to ask them to release the lock.
  Release the Lock: If you have the necessary authorizations, you can manually delete the lock entry in transaction SM12. However, this should be done with caution, as it may lead to data inconsistencies if the other user is still working on the lot.
  Check Background Jobs: Use transaction SM37 to check if there are any background jobs that might be processing the inspection lot. If a job is running, you may need to wait for it to complete.
  System Restart: In rare cases, if the lock persists due to a system error, a system restart may be required to clear the locks. This should be done by your SAP Basis team.
