• What is the cause and solution for SAP error message /PM0/3FW_MESSAGES020 - Deletion is not possible. The object is locked ?

  The SAP error message /PM0/3FW_MESSAGES020 indicates that a deletion operation cannot be performed because the object in question is currently locked. This typically occurs in various SAP modules when an object (such as a work order, maintenance plan, or other entities) is being accessed or modified by another user or process.
  Causes:
  
  Object Locking: The object you are trying to delete is locked by another user or transaction. This can happen if someone else is currently editing the object or if a previous transaction did not release the lock properly.
  Background Jobs: Sometimes, background jobs or processes may hold locks on objects, preventing deletion.
  Transaction Errors: If a transaction was interrupted or did not complete successfully, it might leave the object in a locked state.
  Authorization Issues: In some cases, the user may not have the necessary authorizations to delete the object, leading to a perceived lock.
  
  Solutions:
  
  
  Check Lock Entries: Use transaction code SM12 to check for lock entries. You can search for the specific object or user to see if there are any active locks. If you find a lock that is no longer needed, you can delete it (if you have the necessary authorizations).
  
  
  Wait and Retry: If the object is locked by another user, you may need to wait until that user has completed their work and released the lock. You can communicate with the user if necessary.
  
  
  Check Background Jobs: Use transaction code SM37 to check for any background jobs that might be holding locks on the object. If you find a job that is causing the lock, you may need to wait for it to complete or contact the job owner.
  
  
  Transaction Rollback: If a previous transaction did not complete properly, you may need to investigate and possibly roll back that transaction to release the lock.
  
  
  Authorization Check: Ensure that you have the necessary authorizations to delete the object. If not, contact your SAP security administrator to obtain the required permissions.
  
  
  System Restart: In rare cases, if the lock persists and cannot be resolved through the above methods, a system restart may be necessary to clear any lingering locks. This should be done with caution and typically requires coordination with your SAP Basis team.

  SAP Notes: Check SAP Notes for any known issues related to the specific object type you are working with. Sometimes, there are specific patches or updates that address locking issues.
  
  
  Documentation: Review SAP documentation related to the specific module you are working with (e.g., PM for Plant Maintenance) for additional insights on object management and locking behavior.
  
  
  By following these steps, you should be able to identify the cause of the lock and take appropriate action to resolve the issue.
