Sub Contract - Cost variance not creating or posting to GL

SOLVED

Hi;

Verision 6.5 patch level 36

We have set up subcontracting for purchasing; the provisional cost is calculating correctly and the receipt value to GL and stock is correct. However; if the average cost of the raw material changes during the contract period there is no cost adjustment happening on the received item. On the OE enquiry we can see the variance that we expect but the average cost of the parent item is not corrected/updated.

What parameter/setting are we missing to achieve a cost adjustment when the subcontract is completed? Or does the program not do this?
