To sell product bundles and sets, you add the Child Components related list to the Product object’s page layout. If you’ve set up your store using the Commerce Setup Assistant or created product sets before, the related list is already added. You then create a product relationship type for both bundles and sets. Most stores already have the product relationship types created. For out-of-the box product bundle support, your store must have the Cart Calculate API enabled.
Required Editions
Enable the Cart Calculate API (CCA)
Make sure that CCA is enabled for your store before you create a product bundle or set. As of the Spring '24 release, CCA is enabled by default for LWR stores.
If CCA isn’t enabled, product bundles and sets require further customization. See Cart Calculate API.
