  Error Message
  WOD1021: Purchase order &2 is currently locked by user &1
  
  &2 = Purchase order number
  &1 = User ID who currently holds the lock
  
  
  Cause
  This error occurs because the purchase order you are trying to access or modify is currently locked by another user. SAP uses a lock mechanism to prevent multiple users from editing the same document simultaneously, which could lead to data inconsistencies.
  
  The lock is set when a user opens the purchase order for editing.
  Until the user saves or exits the transaction, the lock remains active.
  If the user has the document open in edit mode or the session is still active, other users cannot make changes.
  
  
  Solution
  
  
  Check who holds the lock:
  
  The message shows the user ID (&1) who currently has the lock.
  Contact that user to check if they are still working on the purchase order.
  
  
  
  Wait or ask the user to release the lock:
  
  The user holding the lock should save and exit the transaction to release the lock.
  If the user is inactive or has left the session open, ask them to log off or close the transaction.
  
  
  
  Manually remove the lock (if necessary and authorized):
  
  If the user is not available or the lock is orphaned (e.g., due to a system crash or session timeout), a system administrator can remove the lock.
  Use transaction SM12 (Lock Entries) to find and delete the lock entry for the purchase order.
  
  Enter the purchase order number or user ID to filter.
  Select the lock entry and delete it.
  
  
  Warning: Deleting locks manually should be done carefully to avoid data inconsistencies.
  
  
  
  Check for system issues:
  
  Sometimes locks remain due to system errors or network issues.
  Ensure that the SAP system is running properly and users are logging off correctly.

  Best practices:
