How do I adjust inventory valuation for a certain item?

SOLVED

We have the module Bill of materials, we typically receive an order from a customer for an item (Program) that has to be built.  We create an invoice for that item (Program) and in a few days when we have enough orders to build the item (Program) it will create a BR and that is sent to our vendor.  Once we receive the built product then they are received into inventory.  This is what it has created.  We over distributed the Program by creating an Sales Order at an incorrect COG so on the GL it will understate the COG and overstate the Inventory asset.  I know how to correct the GL but not the inventory valuation because I am not adjusting quantity just the COG.  Any help would be greatly appreciated.
