D365 has a very good functionality of creating PO (Direct delivery) from SO but it would much better if they can extend this functionality. Our scenario - currently, we are having multiple suppliers for one item and Direct delivery is only looking for Prime for that item. If we have sales order with 50 lines and 50 items have 5 prime suppliers in total then system will create 5 different purchase orders but we can buy 50items from one supplier as it is our second approved supplier. I would suggest to have a dropdown menu to choose supplier in header level of direct delivery screen and value in this dropdown will change supplier account on each line. I hope, above make sense.
