  The SAP error message /PF1/MSG_PO450 Forwarding is not possible; items are locked typically occurs in the context of Purchase Orders (POs) when there are issues related to item locks. This can happen in various scenarios, such as when multiple users are trying to access or modify the same purchase order simultaneously, or when a purchase order is in a state that prevents further processing (e.g., it is being edited or is in a workflow).
  Causes:
  
  Concurrent Access: Another user or process is currently editing or processing the same purchase order or its items.
  Workflow Status: The purchase order may be in a workflow state that prevents forwarding or further processing.
  System Lock: The system may have placed a lock on the purchase order due to a previous transaction that has not been completed or released.

  Solutions:
  
  
  Check for Locks: 
  
  Use transaction code SM12 to check for locks on the purchase order. You can look for locks associated with the user ID or the specific purchase order number.
  If you find locks that are no longer needed, you can delete them (if you have the necessary authorizations).
  
  
  
  Wait and Retry: If another user is editing the purchase order, you may need to wait until they finish and release the lock before you can proceed.
  
  
  Review Workflow: If the purchase order is in a workflow, check the workflow status and see if it can be released or if any actions are required to move it forward.
  
  
  Check Document Completeness: Ensure that all required fields in the purchase order are filled out correctly. If there are any missing or incorrect entries, correct them and try again.
  
  
  Contact Support: If the issue persists and you cannot identify the cause, consider reaching out to your SAP support team or system administrator for further assistance.
