Why does dropship purchase order need a warehouse

I’ve created a purchase order for my supplier to do by dropship. I’m confused why the system needs a warehouse for the item to be delivered to? Since it’s dropship doesn’t that mean it doesn’t go into my warehouses? is this just a bug?

Is Item in question a stock item?

As per the standard design, if you are creating Purchase Order for stock item, then Warehouse field becomes a mandatory field. But as suggested, we could ignore that validation in case of drop-shipping.

Can you please create Github Issue for this suggestion?
