• What is the cause and solution for SAP error message M3587 - The planning material & is locked by the user & ?

  The SAP error message M3587 indicates that a planning material is currently locked by a user, which prevents other users from making changes to that material. This typically occurs in the context of materials planning, where multiple users may be trying to access or modify the same material data simultaneously.
  Cause:
  
  User Lock: The material is locked by a user who is currently editing or processing data related to that material.
  Session Timeout: Sometimes, a user may have left a session open, causing the lock to persist even after they have finished their work.
  System Error: Occasionally, system errors or crashes can lead to locks not being released properly.
  
  Solution:
  
  
  Identify the Locking User: 
  
  Use transaction code SM12 to view the list of locks in the system. You can filter by the material number or user ID to find out who is holding the lock.
  
  
  
  Contact the User: 
  
  If you identify the user who has locked the material, reach out to them to see if they can release the lock by completing their task or logging out.
  
  
  
  Release the Lock: 
  
  If the user is unavailable or the lock is no longer needed, an administrator can manually delete the lock entry in transaction SM12. However, this should be done with caution to avoid data inconsistency.
  
  
  
  Check for Background Jobs: 
  
  Sometimes, background jobs may also hold locks. Check if there are any running jobs that might be causing the lock.
  
  
  
  Review System Logs:
