Two objects that are found within Order Management are:
Fulfillment Order. 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.
Payment Summary. A Payment Summary is a record that represents a payment made for an order or
part of an order. A Payment Summary has a lookup relationship to both Order Summary and Invoice
objects, and it contains information such as the payment amount, method, status, etc.
