STO cancel partial quantity

We are using the STO procedure to send items from one plant to another. We create initially a PO and the we create a delivery. We use the movement type 641 so as to have stock in transit. As soon as the items arrive at the receiveing plant we use a movement type to make the receipt.

In some cases during transportation part of the quantity might be damaged. The receiving plant will receive only the quantities that are in good condition. As next step I need to make a procedure so as to reverse the movement type 641. So as not to have a part of the quantity in transit. Get this quantity back in the stock of the supplying plant and then do the procedure to destroy these quantities.
