On a Purchase Order that is linked to a drop-ship Sales Order, only the item lines for the vendor on the purchase order should import to that particular purchase order. In other words, BC should know that the item on Line 10000 on the Sales Order comes from vendor ABC Mart, and the item on Line 20000 comes from vendor Jack Donuts. When creating a purchase order for ABC Mart, and select the Sales Order, only line 10000 should be imported. Currently, both lines are imported and you have to manually delete the line(s) that are not for that vendor.
