Subcontracting with Scrap and Co-product

Question

My requirement is as follows
: Subcontracting Scenario
    In Bom-
     For  Each  Finished material *F1*
                     1.Material-- X1 ---2nos.
                     2.Material-- X2 ---2nos.
                     3.Co-Prodcut-- X3 --1 no.
                     4.Scrap 10% of material  X1 .
I had raised a subcontracting P.O for subcontracting Vendor  V1  for 2 qty of material F1.
As i dont have stock of BOM(X1,X2) i had raised a normal p.o for vendor  V2  and asked him to deliver the material  X1 , X2  to subcontracting vendor V1 directly.
Here  in the  normal P.O for vendor V2  the qty for X1 , X2 is 10 each.
At the end of the subcontracting scenario
i should end up with
F1 --2qty
X1 --6 qty (10 - 2*2)
X2 --6 qty (10 - 2*2)
Co-product  X3 - 1 qty
Scrap-- 10% of  X1
Pl can any one explain how to proceed for the above scenario with config settings, tcodes, postings.
reply will be highly appreciated
Thanks

Hi
You have to create BOM for Finished product F1 with components X1 and X2.Now the coproduct which is to be produced will be defined as the coproducts and will be entered in BOM as negative quantity.
For supplying materials directly to subcontarctor - you have to create Purchase order for X1 and X2 with 10 qty and delivey tab at PO line item you need to define  Vendor which is subcontractiong vendor and Tick Sub contratcor .
As soon as you do the GR for this PO then material will be shown as stock lying at subcontracting vendor .
Now subcontracting  vendor has done the acticity and material reached  to you do the GR for Sub contracting PO .
For FG 2 qty ,automatic consumption of the raw material of 4 qty of X1 and X2 and coproduct will come into pictuer using 531 mvt type.
