Costing method is set as Perpetual average,need to do inventory valuation at sub inventory level.

Summary:

I have a scenario where the customer wants to receive(Miscellaneous receipt) some materials with 1$ unit price and store it in separate sub inventory, then also same materials should get procured at any price but not particularly same as 1$ and stored in separate sub inventory.

Now, when it comes to inventory valuation, we want a separate valuation for the same materials at the sub inventory level with a separate price(price at the time of receiving in sub inventory, not the Item cost).

is this possible if yes then please help with reference documents or can guide us with step by step procedure to achieve this goal?
