A customer orders 10 products.

The number of Fulfillment Orders that would be created for this order is one per destination, totaling 3. A Fulfillment Order is a record that represents a group of products in an order that are fulfilled together from the same location. A Fulfillment Order has a lookup relationship to the Order Summary object, and it contains information such as the fulfillment location, delivery method, status, etc. The number of Fulfillment Orders created depends on three factors: Fulfillment Location, Delivery Method and Recipient Address. These factors determine how the Order Items are grouped and allocated to Fulfillment Orders based on routing rules and inventory availability. In this case, since the products must be shippedto three different locations, three Fulfillment Orders are created for each destination.
