• What is the cause and solution for SAP error message /SAPAPO/RELH009 - User &1 is processing hierarchy &2 (Only possible to display) ?

  The SAP error message /SAPAPO/RELH009 indicates that a user is trying to modify or interact with a hierarchy in SAP Advanced Planning and Optimization (APO) that is currently being processed by another user. The message states that the only action possible is to display the hierarchy, meaning that the user cannot make changes until the other user has finished their processing.
  Cause:
  
  Concurrent Access: The hierarchy is locked by another user who is currently processing it. This is a common scenario in systems where multiple users may need to access the same data simultaneously.
  Lock Mechanism: SAP uses a locking mechanism to prevent data inconsistencies. When one user is working on a hierarchy, it is locked for others to ensure that changes are not made concurrently.
  
  Solution:
  
  Wait for Release: The simplest solution is to wait until the other user has finished processing the hierarchy. Once they are done, the lock will be released, and you will be able to make your changes.
  Contact the User: If you know who the user is, you can contact them to see if they can finish their work or release the lock.
  Check Lock Entries: You can use transaction code SM12 to check for lock entries. This will show you which user is holding the lock on the hierarchy. However, be cautious when dealing with locks, as forcibly removing a lock can lead to data inconsistencies.
  Review User Permissions: Ensure that your user role has the necessary permissions to access and modify the hierarchy once it is available.
