  Solution:
  
  Wait and Retry: If the order is being processed by another user, wait for them to complete their task and then try again.
  Check Active Sessions: Use transaction codes like SM04 or AL08 to check for active sessions and see if the user who is processing the order can be identified.

  Using transaction SM12 to find and delete the lock entries related to the warehouse order.
  Ensure that you have the necessary authorizations to perform this action.
