• What is the cause and solution for SAP error message SOMU_T100002 - Long text link navigation mapping &2 already locked by &1 ?

  The SAP error message "SOMU_T100002 Long text link navigation mapping &2 already locked by &1" typically indicates that there is a conflict in accessing a long text link mapping in the SAP system. This error occurs when one user or process is trying to access or modify a long text mapping that is already locked by another user or process.
  Cause:
  
  Concurrent Access: Another user or transaction is currently editing or has locked the long text mapping.
  Session Issues: A previous session may not have released the lock properly, leading to a stale lock.
  System Configuration: There may be issues with the configuration of the long text mapping or the way locks are managed in the system.
  
  Solution:
  
  
  Identify the Lock: 
  
  Use transaction code SM12 to check for locks in the system. You can filter by the object name or user to find out who is holding the lock.
  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 lock is held by another user who is actively working, it may be best to wait until they finish their work and release the lock.
  
  
  Check for Stale Locks: 
  
  If you suspect that the lock is stale (e.g., due to a session crash), you can manually delete the lock in SM12 if you have the appropriate permissions.
  
  
  
  Communicate with Users: If you are in a multi-user environment, communicate with the user who holds the lock to understand their needs and coordinate access.
  
  
  Review System Configuration: If this issue occurs frequently, it may be worth reviewing the configuration of the long text mapping and the locking mechanism in your SAP system.
