Select the applicable product(s). The operation of this window is basically the same as the Usage Types window.
Select Only discount the in-advance portion of in-advance product charges to prevent a discount being applied on the "catch-up" portion of an in-advance product. This affects only the first bill of an in-advance product if the product was assigned mid-month. For example, if a product with a monthly charge of $20 is added on 4/15, the 5/1 bill would be $30 without a discount ($10 for the 4/15-4/30 portion and $20 for the in-advance 5/1-5/31 portion). If this option is selected, the discount only applies to the in-advance portion ($20 for 5/1-5/31).
Select Allow Chargeback of discounts on in-advance and credit-on-disconnect products to calculate and bill chargebacks for in-advance products that have been discounted by the plan.
Select Exclude overridden product charges to exclude overridden product charges from being calculated in the discount.
