How Shipments Are Created
For the latest version of Commerce Server 2007 Help, see the Microsoft Web site.
Commerce Server creates shipments based on shipping method and shipping address information that you collect from the user.
From your site code, you ask the user which items to ship to which address, and which shipping method to use. You then set the ShippingMethodId and ShippingAddressId properties of each LineItem object in the user's basket.
The Total pipeline uses this information to create Shipment objects and adds them to the OrderForm object. Each Shipment object references a set of line items, an address, and a shipping method.
How Commerce Server Creates Shipments
When you run the Total pipeline, Commerce Server uses the information that you added to the LineItem objects to create Shipment objects. The following three pipeline components play a role in creating shipments:
The Splitter pipeline component examines all the items in the basket, and groups the line items according to the shipping address and the shipping method. It then creates one Shipment object for each group of line items, and sets the following properties of each Shipment object:
ShippingAddressId indicates where the items will be shipped.
ShippingMethodId indicates which method to use to ship the items.
LineItemIndexes identifies which items to include in this shipment.
For example, consider a basket that contains four line items that will be shipped to two addresses by using two shipping methods, as shown in the following table.
Line Item |
Shipping Address |
Shipping Method |
|---|---|---|
A |
Home |
Ground |
B |
Home |
Air |
C |
Work |
Ground |
D |
Home |
Ground |
The Splitter pipeline component will create three shipments for this basket, as shown in the following table:
Shipment |
Line Items |
Shipping Address |
Shipping Method |
|---|---|---|---|
1 |
A, D |
Home |
Ground |
2 |
B |
Home |
Air |
3 |
C |
Work |
Ground |
Note
By default, the Splitter pipeline component groups line items based on the ShippingAddressId and ShippingMethodId properties. However, you can configure the Splitter component to group the line items according to custom properties such as weight and quantity.
After the Splitter pipeline component creates the Shipment objects, the ShippingMethodRouter pipeline component identifies and invokes the correct pipeline component to calculate the cost of each shipment. The pipeline components that calculate the shipping costs are called shipping cost calculators.
The only shipping cost calculator that Commerce Server includes is the StepwiseShipping pipeline component. The StepwiseShipping pipeline component calculates the cost of a shipment based on the cost of the items, the quantity of the items, or the combined weight of the items.
Note
Use the Commerce Server Customer and Orders Manager to specify whether the StepwiseShipping pipeline component should calculate the shipment cost based on subtotal, quantity, or weight.
Note
You can create a custom shipping cost calculator by creating a new pipeline component and by using the Commerce Server Customer and Orders Manager to associate the new component with a shipping method.
