Inventory Valuation For Expense

Hi - We have 2 types of Subinventories -

1) Asset

2) Expense

Lets assume the Part A with STD cost 10 with qty 1

1a) When we perform the Misc. receipt in Asset Subinventory, the distribution is

Dr. INV Val

Cr. Offset

2a) When we perform the Misc. receipt in Expense Subinventory, the distribution is

Dr. Expense

Cr. Offset

3) But I can run the Inventory Valuation based on both i.e. based on Asset and Expense

3a) The Inventory Valuation based on Asset shows 10 for Part A

3b) The Inventory Valuation based on Expense shows 10 for Part A

So can you please help me in understanding that (3b) will also be considered as Inventory Valuation ?
