Production order product costing
I have created a production order with material A (bom is setup with materials B and C which will create material A). I release the producition order then post the goods issue and reciept. Material A is created using B and C, but the cost of material B and C is not transferrred material A which was just created...instead it is taking the cost of material A before the production order was issued and recieved. How do i get the cost of B+C to = A (to show in the accounting documents) then get transferred into the moving price of A?
