The names of several schema field groups have changed. See the document on field group name updates for more information.
Commerce Details is a standard schema field group for the XDM ExperienceEvent class, used to describe commerce data such as product information (SKU, name, quantity), and standard cart operations (order, checkout, abandon).
||Commerce||An object that describes product returns, warranty registration, and shopping cart/order processes.|
||Array of Product list items||A list of items representing the product(s) selected by a customer, with specific options and pricing at a specific point of time (which may differ from the product record).|
