Hello all. Not sure where to post. Is there a way to link a new sales order line to an existing drop shipment purchase order? Example: SO1234 has 5 lines, all of which have been placed on drop shipment purchase order PO4567. Tomorrow, customer requests 1 more item and is added as line 6 to SO1234. I would like to have line 6 added to PO4567 and have the same link between the 2 transactions as the first 5 lines. Right now, if I add line 6 to the sales order, it asks for either a new Drop Ship or Spec. Order. If I add it directly to the Purchase Order, it does not have a link to the sales order. Thank you!

IIRC those links can only be done on create of the transaction, not on an edit.

There is an Enhancement Request already filed for this.

Thank you @Rob Cady and @Suitestallion. Its what I thought.
