Product and Pricing are set up with CPQ as the source of record. This means that CPQ is responsible for managing the product catalog, price books, price rules, discounts, and other aspects of product configuration and pricing. B2B Commerce syncs products and prices from CPQ using a scheduled job or an API call1.
