Use the B2C Commerce API to add multiple coupon codes for the same coupon to a cart.
The behavior controlled by this setting is enforced regardless of how the coupon is added to
basket: B2C Commerce Script API, SHOP API, AddCouponToBasket or
AddCouponToBasket2 pipelets.
Each unique code added to a basket results in a unique CouponLineItem being
added. Conversely, every CouponLineItem represents a single coupon code.
When an order is created, all coupon codes associated with the order are marked as
redeemed.
The logic for retrieving active customer promotions is the same as for other promotions. For
example, PromotionMgr.getActiveCustomerPromotions() returns the same
information whether a promotion is triggered in the cart by one coupon code or multiple.
When using this coupon type with a Choice of Bonus
Product
BonusDiscountLineItem created by B2C Commerce is associated with the
triggering coupon code. The triggering coupon code is determined by the position of the coupon
code and the bonus discount line item within the basket. You can access this association via
the B2C Commerce Script API, so that the storefront application can show that the bonus
products relate to a specific coupon code. If a coupon code is removed from the cart, only the
related bonus products are also removed from the cart.
