When an order contains products that will need to be shipped to multiple addresses, multiple fulfillment orders will be created. A fulfillment order is a record that represents a part of an order that is fulfilled by a specific location and shipped to a specific address. A fulfillment order can have one or more fulfillment order lines, which are the products that are included in the fulfillment order. An order can have one or more fulfillment orders, depending on how many locations and addresses are involved in the order fulfillment. Reference: Order Management Objects, Order Fulfillment Flows
