Order Type
Indicates whether a customer order is a regular order or a blanket order. Both types have an order header and order lines. The blanket order gives you the added ability to assign a blanket quantity to an order line and then assign release quantities to each blanket line.
For example, blanket orders help you track order information for a customer who orders 500 of an item but only wants to receive 50 once a month for 10 months.
