ATO Item using Inter-Org

Hi,

Here is the scenario

I booked an Order for ATO Finished goods Item (configured part or star item) which is based on ATO Model.

The ATO Item is to be shipped from our warehouse say W1-warehouse location but made in M1- mfg location. Sourcing rule is defined to make this part in M1.

Both W1 and M1 belong to same Operating Unit.

So the ATO Item is setup as Buy item in W1 and make item in M1.

When I book the Order and progress the ATO Line item, it goes to PO-Requested status. It goes via creating Internal Requisition-> Internal sales order> route
