• What is the cause and solution for SAP error message /PLMB/BA_GSS201 - Synchronization unit &1 locked by user &2 ?

  The SAP error message /PLMB/BA_GSS201 Synchronization unit &1 locked by user &2 typically indicates that a synchronization unit (which is a part of the SAP PLM (Product Lifecycle Management) module) is currently locked by another user. This can happen when one user is editing or processing a synchronization unit, preventing other users from making changes until the lock is released.
  Cause:
  
  User Lock: Another user is currently working on the synchronization unit, which prevents concurrent access.
  Session Timeout: A user may have left a session open, causing the lock to persist even if they are no longer actively working on it.
  System Error: Sometimes, a system error or crash can leave a lock in place unintentionally.
  
  Solution:
  
  Wait for Release: The simplest solution is to wait until the user who has locked the synchronization unit completes their work and releases the lock.
  Contact the User: If you know who the user is, you can contact them to see if they can release the lock.
  Check Lock Entries: You can check the lock entries in the SAP system using transaction code SM12. This will allow you to see which user has locked the synchronization unit.
  Delete Lock Entry: If necessary and if you have the appropriate authorizations, you can delete the lock entry from SM12. However, this should be done with caution, as it may lead to data inconsistency if the other user is still working on the unit.
  System Administrator: If you are unable to resolve the issue, contact your SAP system administrator for assistance. They may have additional tools or permissions to help resolve the lock.
