In Microsoft Dynamics GP, a blanket purchase order lists a single item and its quantities that will be delivered in a series of shipments, usually on specific dates. Blanket purchase orders allow you to make long-term agreements with vendors to purchase the same item—usually to receive a volume discount or to be sure of obtaining items that are hard to get. The agreement you make with the vendor can be based on the total cost of the item or on the total quantity of the item.
You’ll use the Purchasing Blanket Detail Entry window to enter line items for the blanket purchase order. The line items you enter for a blanket purchase order must be the same item number. The item will be shipped to your business to be received into your inventory.
Control Blanket Line Item
The first line item entered for a blanket purchase order is called the “control blanket line item” and has the line number 0. This is the line item that the blanket line items are based on. For example, you might enter a quantity of 10 for the control blanket line item and then enter three blanket line items with a quantity of 4, 2, and 4 each. The control blanket line item isn’t included in tax amounts, in the purchase order’s subtotal, or printed on purchase orders. If you delete the control blanket line item, all blanket line items are deleted. A control blanket line item can’t be deleted if a blanket line item has been received against. Unlike blanket line items, the control blanket line item can’t be received or invoiced against.
