how to derive Inventory valuation account from PO charge account for PO delivery

Summary:

Hi,

I'm testing the process of standard PO receipt and I was hoping that Receipt accounting and cost accounting could derive the Accrual and Inventory Valuation account from PO distribution which are configured in TAB rule, so that we dont have to setup those account rules again in receipt and cost accounting SLA rules, it turns out that the accrual account can be captured in the source Code Combination Identifier in receipt account, but the inventory valuation account cannot be derived in the same way.

Since we are using the predefined account rules in our SLA, I was wondering if it is the expected behavior that Inventor valuation account cannot be derived from PO tab rule and we need to define it again in cost accouting?
