S/4HANA Cloud - The source of delivery address in Purchase order form determination

Hi,

I'm utilizing the information source FDP_EF_PURCHASE_ORDER_SRV for the Purchase Order form.

There is Ship to enactment code node nether PurchaseOrderNode. I request to cognize what the root of ShipToParty node is.

Is it the transportation code nether PO enactment item?

What happens if determination are aggregate PO enactment items with antithetic transportation addresses?

Thanks

Tri
