such scenario is not possible with subcontract purchase orders. They are used for a simple form of subcontracting, where the goods issue of components is made through back flushing when a goods receipt for the finished material is posted.
If you want do such with a purchase order, then you have to change the PO before you perform a receipt. You would need to change the PO quantity to the quantity that you will receive, and you also need to change the price, and you need to change the BOM in your PO item Material tab. Quite a lot changes that need to be accomplished to cover such process, so it is not really a desirable process.
Such complex subcontracting processes should be done with production orders, and only order the service via purchase orders.
