Charge account for an expense item not defaulted from item expense account

Hi

I have setup an item as expense ("Inventory Asset" and "Costing Enabled" flags unchecked) and made a requisition for that item with destination type inventory. Then I auto-created a PO from the requisition and received it in the inventory.

The resulting journal of the receipt got the expense account from the organization parameters and not from that defined on the item level.

How can I make the resulting journal take the charge account from the item expense account and not from the organization parameters?

Thanks

Nader
