• What is the cause and solution for SAP error message PPH_DD090 - Product in Plant &1 and MRP Area &2 is locked by user &3 ?

  The SAP error message PPH_DD090 indicates that a product in a specific plant and MRP (Material Requirements Planning) area is locked by a user. This typically occurs when a user is performing an operation that requires exclusive access to the product data, such as planning, changing, or executing transactions related to that product.
  Cause:
  
  User Lock: The product is currently being accessed or modified by another user, which prevents other users from making changes to it.
  Transaction in Progress: A transaction that involves the product is still in progress, leading to a lock.
  System Error: Sometimes, a system error or an unexpected termination of a transaction can leave a lock in place.
  
  Solution:
  
  Wait and Retry: If the lock is temporary, waiting for the other user to complete their transaction may resolve the issue. You can retry the operation after some time.
  Identify the Locking User: Use transaction code SM12 to check for locks. You can see which user is holding the lock and what specific entries are locked.
  Contact the Locking User: If possible, communicate with the user who is holding the lock to understand if they can release it or if they are done with their transaction.
  Release the Lock: If the locking user is unavailable and 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 data.
  Check for Background Jobs: Sometimes, background jobs may hold locks. Check transaction SM37 to see if any background jobs are running that might be causing the lock.
  System Restart: In rare cases, a system restart may be necessary to clear persistent locks, but this should be done as a last resort and typically requires coordination with your IT department.
