Simple costing

There is scenario like Job work sales order against Sub contract purchase order, which same received from one of the internal customer. Now business would like do simple costing based on Job work sales order and subsequent settlement also. Let us know whether any possibilities to do like that in SAP as per standard best practice.

In business point of view, we are thinking to assign required materials in Sales order costing view and activities also. Is it possible to consume those values, while doing the any activity? Kindly explain brief, I hope it would very helpful to us.
