Hi Ahmed,

You cannot - for your own good.

You need to create another stock move for the same you have done the mistake.

Alternative:   You can have an app which provides facility to cancel work orders and cancel inventory moves while cancel manufacturing order, even if work order was finished and inventory moves was done or transferred.

Thanks.
