• What is the cause and solution for SAP error message Q0158 - Master inspection characteristic is being processed by &1 ?

  The SAP error message Q0158, which states "Master inspection characteristic is being processed by &1," typically occurs in the Quality Management (QM) module when a master inspection characteristic (MIC) is locked by another user or process. This can happen during various operations, such as creating or modifying inspection plans, inspection lots, or characteristics.
  Cause:
  
  Locking by Another User: The MIC is currently being edited or processed by another user or transaction.
  Background Jobs: A background job may be processing the MIC, causing it to be locked.
  Transaction in Progress: A transaction that involves the MIC is still in progress, preventing other transactions from accessing it.
  
  Solution:
  
  Check for Locks: Use transaction code SM12 to check for any locks on the MIC. You can look for the user ID mentioned in the error message (&1) to identify who is holding the lock.
  Wait and Retry: If another user is working on the MIC, you may need to wait until they finish their transaction. You can communicate with the user to find out when they expect to complete their work.
  Release Locks: If you determine that the lock is no longer valid (e.g., the user has logged off unexpectedly), you can manually delete the lock using transaction SM12. However, be cautious with this approach, as it may disrupt the other user's work.
  Check Background Jobs: Use transaction SM37 to check for any background jobs that might be processing the MIC. If you find a job that is causing the lock, you may need to wait for it to complete or consult with your system administrator.
  System Restart: In rare cases, if the lock persists and cannot be resolved, a system restart may be necessary, but this should be done with caution and typically as a last resort.
