  Solution:
  
  Check for Locks: Verify if the order is being edited by another user. You can use transaction code SM12 to check for locks on the order. If you find a lock, you may need to wait for the other user to finish or contact them to release the lock.

  Consult with IT Support: If the issue persists, it may be necessary to consult with your IT support team or SAP Basis team to investigate further, especially if there are system-level issues or bugs.
