When entering a Blanket Purchase Order a main (0) line is entered on the purchase order with a Purchases account. When release shipment lines are entered on the PO to relieve the blanket the distribution account does not carry to the new lines. I tested this in GP2016 and GP2018 and it does not work. The account defaults from the vendor or from the Purchases account in Purchasing Posting Accounts Setup. If this gets changed on the blanket line item it defaults incorrectly to the release line items from the vendor or posting accounts setup and not the blanket item setup.
