• What is the cause and solution for SAP error message K9155 - Layout & is being changed by user & . ?

  The SAP error message K9155, which states "Layout & is being changed by user &," typically occurs in the context of SAP Controlling (CO) when a user attempts to access or modify a layout that is currently being edited or is locked by another user. This can happen in various reporting transactions, such as those related to cost center accounting or internal orders.
  Cause:
  
  Concurrent Access: Another user is currently editing the same layout, which prevents you from making changes.
  Lock Mechanism: SAP uses a locking mechanism to prevent data inconsistencies. If a layout is locked by another user, you will receive this error.
  Session Issues: Sometimes, a session may not release the lock properly, leading to this error even if the other user has finished editing.
  
  Solution:
  
  Wait and Retry: If another user is editing the layout, wait for them to finish and try again later.
  Check User Locks: You can check which user is currently editing the layout by using transaction code SM12 to view and manage locks. If you have the necessary permissions, you can release the lock if it is no longer needed.
  Contact the User: If you know who is editing the layout, you can contact them to see if they can finish their work or save and exit.
  Use a Different Layout: If possible, try using a different layout that is not currently being edited.
  Session Management: If you suspect a session issue, log out and log back into SAP to clear any stale locks.
