      • addOrderLevelDiscount

        public DiscountRAO addOrderLevelDiscount​(CartRAO cartRao,
                                         boolean absolute,
                                         java.math.BigDecimal amount)
        creates a DiscountRAO for the given CartRAO based on the input. Adds the discount to the cart RAO and recalculates the totals of the given CartRAO. The absolute parameter determines if the discount is an absolute one or a percentage based one. If absolute is set to false, the amount is read as an percent value, e.g. 10 for 10% (and not 0.1 for 10%)
