Product Pipeline
The Product pipeline runs components that compute price and discount information on individual products. This pipeline is often used to compute information that is displayed on the Product.asp page.
The template for this pipeline is Product.pct.
The Product pipeline consists of the following stages:
Product Info Stage
Shopper Information Stage
Item Price Stage
Item Adjust Stage
Inventory Stage
Product Info Stage (Product Pipeline)
The Product Info stage contains components that retrieve product information about the items in the items list from the site database. If information about a given item cannot be retrieved, Product Info stage components mark the item for deletion by creating a delete key in the item Dictionary object, and giving it the value one (1).
After the Product Info components have been executed, the RequiredProdInfo component in the Product Info stage goes through the items list, deleting every item marked for deletion.
The components related to this stage are shown in the following table.
| Component | Description |
| QueryCatalogInfo | Retrieves catalog information for every item in the order form. Uses the Commerce Server 2000 Product Catalog System. Marks missing items for deletion and adds basket errors if necessary. |
| QueryProdInfoADO | Executes a database query, based on the SKUs in the items list of the OrderForm object, and puts the returned data in the items collection of the OrderForm object. Marks missing items for deletion and adds basket errors as necessary. |
| RequiredProdInfo | Deletes items marked for deletion and writes the appropriate error messages. |
Shopper Information Stage (Product Pipeline)
The Shopper Information stage adds information about the user to the OrderForm object.
The components related to this stage are shown in the following table.
| Component | Description |
| DefaultShopperInfo | Copies information from the Shopper dictionary in the Context dictionary to the OrderForm object. |
Item Price Stage (Product Pipeline)
The Item Price stage sets the _iadjust_regularprice key on each item in the order form.
The Item Price stage contains components that set the _iadjust_regularprice key for each item in the items list, as well as components that verify this value has been set. If this value cannot be set, an error occurs.
This initialization ensures that the _iadjust_regularprice dictionary key entry contains the most current price information for the given SKU.
The components related to this stage are shown in the following table.
| Component | Description |
| DefaultItemPriceCy, DefaultItemPrice | For each item in the items list, sets the _iadjust_regularprice key to the value stored in the _product_list_price key. |
| RequiredItemPriceCy, RequiredItemPrice | Ensures that _iadjust_regularprice key is set for each item in the items list. |
Item Adjust Price Stage (Product Pipeline)
The Item Adjust Price stage contains components to initialize the value of the_iadjust_currentprice key. When the stage is complete, _iadjust_currentprice key contains the current price of the item, adjusted for sales or promotions.
If no sale or promotion component is included in this stage, the key is set to the value stored in _iadjust_regularprice key.
Once the item._iadjust_currentprice key is set for an item, the item cannot be adjusted a second time. For example, if a stage includes both an ItemPromo and a SaleAdjust component, and an item on the order form qualifies for both the promotion and the sale adjustment, the _iadjust_currentprice key of the item is set by the component executed first within the stage. This generalization applies for any combination of Item Price Adjust stage components that you include in your pipeline.

Note
- Do not use this stage to calculate discounts in new pipelines. Use the OrderDiscount component in the Order Adjust Price stage of the Plan pipeline. The OrderDiscount component uses the Commerce Server 2000 Targeting System to apply item and order discounts.
The components related to this stage are shown in the following table.
| Component | Description |
| ItemPromo | Adjusts the value of the _iadjust_currentprice key, based on promotions. |
| SaleAdjust | Determines whether an item is on sale. If it is, the SaleAdjust component sets the _iadjust_currentprice key of the item to the value stored in the _product_sale_price key. |
| RequiredItemAdjustPriceCy, RequiredItemAdjustPrice | Verifies that the _iadjust_currentprice key exists and has a value. |
Inventory Stage (Product Pipeline)
The Inventory stage contains components that verify that every item ordered is in stock.
The components related to this stage are shown in the following table.
| Component | Description |
| FlagInventory | Flags items in the items SimpleList object that are out of stock. |
| LocalInventory | Checks the OrderForm object to ensure that an item does not require more of a given SKU than is in stock. |
