Hello Raj,
You can find the list of PI sheets from transaction CO64. Select the process order's from the list for which the Control receipe completion has to be forced.
Post selection press Shift+F6 ,you can find the same aspect under PI SHEET menu.Discard the respective elements.
Then go to CO54 (process message monitor) wherein just mention the plant and hit enter. You'll get the list of process messages that are yet to be sent. Select all and hit send.
Post that the status of process order would be updated with 'CRAB - Recipe Discarded'.
Regards,
Rahul
