Review the new B2C Commerce Basket feature in the 20.8 release.
- Basket Product Duplication Considers Product Lists
When basket settings are configured to disallow or merge duplicate product line items, the system now considers product lists, such as wishlists, in addition to SKUs and inventory lists. When a shopper adds a product from a list to a basket, the system can only duplicate an existing product line item that was added from the same list.
