Contract Additional Charge Pricing
Pricing for additional items on a contract is similar to contract line-item pricing. In both cases, the system distinguishes between a price found on a price list and one you enter when net price defaults to zero.
When the list price for the additional charge item is found on a price list, it never changes. If you change the net price, the difference is reflected as a discount.
When a price is not found on a price list and you enter a net price, any changes to the net price resets the list price. In this case, you must enter a manually specified discount.
Fixed additional charge items can represent either a positive or negative amount, depending on the value for item quantity. However, you cannot update item quantity when there is a percentage additional charge. For a percentage additional charge, the system determines whether the item is an uplift or discount based on the amount type of the price list. If the percentage additional charge is not on a price list, the system applies it as an uplift. If you want a percentage additional charge item to be treated as a discount, define it on a discount price list.
