• What is the cause and solution for SAP error message /SAPAPO/SCC145 - Model &2 locked by user &1 (Only possible to display) ?

  The SAP error message /SAPAPO/SCC145 Model &2 locked by user &1 (Only possible to display) typically occurs in the SAP Advanced Planning and Optimization (APO) module when a user tries to modify a planning model that is currently locked by another user. This locking mechanism is in place to prevent data inconsistencies that could arise from simultaneous modifications.
  Cause:
  
  User Locking: Another user is currently working on the model, and the system has locked it to prevent concurrent changes.
  Session Timeout: A user may have left a session open, causing the model to remain locked even if they are no longer actively using it.
  System Configuration: The system may be configured to lock models for specific operations, which can lead to this message if not managed properly.
  
  Solution:
  
  Wait for Release: The simplest solution is to wait until the user who has locked the model completes their work and releases the lock.
  Contact the User: If you know who the user is, 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. This will allow you to see which user has locked the model and potentially release the lock if necessary.
  Release Lock: If you have the necessary authorizations, you can manually delete the lock entry in SM12. However, this should be done with caution, as it may lead to data inconsistencies if the other user is still working on the model.
  Review System Settings: If this issue occurs frequently, it may be worth reviewing the system settings and user practices to minimize locking conflicts.
  
  Related Information:
