Drop Shipment: Revenue account in AR transaction not correct

Hi all,

I have the following scenario:

- OU 1 - Legal Entity 1 - Ledger 1- COA 1- IO1

- OU 2- Legal Entity 2 - Ledger 2 - COA 2 - IO2

I create a drop ship sales order in OU 2.The warehouse selected in the lines belongs to OU1 (IO1)

When I run the Autoinvoice and check my AR transaction in OU2 I realize that the revenue account is not correct. In the autoaccounting setup I have set natural account from standard lines.So I expect that the account is derived from the item in IO2. But what  I see in the revenue account of the AR transaction is the natural account of the item assigned to IO1.
