• What is the cause and solution for SAP error message /UI2/UIAC006 - Catalog &1: Locked by User "&2" ?

  The SAP error message /UI2/UIAC006 Catalog &1: Locked by User "&2" indicates that a specific catalog in the SAP Fiori Launchpad is currently locked by another user. This typically occurs when a user is editing or modifying the catalog, preventing other users from making changes until the lock is released.
  Cause:
  
  User Locking: The catalog is being edited by another user, which places a lock on it to prevent concurrent modifications that could lead to data inconsistency.
  Session Timeout: Sometimes, if a user has an active session that times out without properly releasing the lock, it may still appear as locked.
  System Errors: Occasionally, system errors or crashes can lead to locks not being released properly.
  
  Solution:
  
  Wait for Release: If the catalog is locked by another user, the simplest solution is to wait until that user has finished their work and the lock is released.
  Contact the User: If you know who the user is (as indicated by "&2" in the error message), you can contact them to see if they can release the lock.
  Check Lock Entries: You can check the lock entries in the system using transaction code SM12. Look for the relevant lock entries and see if you can identify the user holding the lock.
  Release Lock: If necessary and if you have the appropriate authorizations, you can manually delete the lock entry in SM12. However, this should be done with caution and ideally after consulting with the user or your system administrator.
  System Administration: If the issue persists, it may be necessary to involve your SAP Basis team or system administrator to investigate further and ensure that there are no underlying issues causing the locks.
