• What is the cause and solution for SAP error message /SAPAPO/CTM1259 - Transaction locked by user &1. Display only ?

  The SAP error message /SAPAPO/CTM1259 indicates that a transaction is locked by a specific user, and the current user is only allowed to display the transaction rather than modify it. This typically occurs in the context of SAP Advanced Planning and Optimization (APO) when multiple users are trying to access the same planning transaction simultaneously.
  Cause:
  
  User Locking: The transaction is currently being edited or processed by another user, which results in a lock being placed on it to prevent data inconsistencies.
  Session Management: The user may have left a session open, or there may be a session timeout that has not been handled properly.
  System Configuration: Certain configurations in the system may enforce strict locking mechanisms to ensure data integrity.
  
  Solution:
  
  Wait for Release: The simplest solution is to wait until the user who has locked the transaction completes their work and releases the lock.
  Contact the User: If possible, contact the user who has locked the transaction to see if they can complete their work or release the lock.
  Check Lock Entries: Use transaction code SM12 to check for lock entries. You can see which user has locked the transaction and potentially delete the lock if it is no longer needed (note: this should be done with caution and typically requires appropriate authorizations).
  Session Management: Ensure that users are properly logging out of sessions and not leaving transactions open unnecessarily.
  System Configuration Review: If this issue occurs frequently, it may be worth reviewing the system configuration and user access settings to see if adjustments can be made to reduce locking conflicts.
