Reverse Subcontracting-Valuation

Hi,

We have a following requirement which is a sort of reverse subcontracting. Have viewed few threads on reverse subcontracting and able to get the desired output from inventory management point of view. However from the valuation perspective, the process is not accepted. Request your suggestions on this pls.

Regular BOM structure is

1. Header 1 (F&30)         -  $1000
   1. Item 1(F)             - $400
   2. Item 2(F)             - $200
   3. Item 3(F)             - $200

Conversion cost of Header 1 is $200 and for some reasons we want the header to be dismantled and brought back to plant as item level stock.

Since we don't want to alter the regular BOM structure, created a subcontracting order, and in the components section, given the items in following structure and the conversion cost is $200.

1. Item 1 (F)                    -              $400 (to be received via 101)
   1. Header 1(F&30)   -             $1000 (to be consumed as 543 (O) )
   2. Item 2(F)             -              $200  (to be received via 545 SC BP)
   3. Item 3(F)             -              $200 (to be received via 545 SC BP)

We are able to post the inventory transactions in the above structure, but the value of Item 1 got posted wrongly. Following are the accounting entries.

We have expected the value of Item 1 to remain as 400 and request your views on possibilities for achieving this.

Thanks
