Some service organizations have items they include in contracts that either add to the price or create a discount. These are defined in Contract Additional Charges (11.5.7).

The Amount type can be fixed (F) or percentage (P).

If the additional charge is a fixed amount, the price list type must be P (price). In this case, the price is considered a fixed amount to be added to or subtracted from the price of the contract for each period. If the additional charge is a percentage, the amount type can be either D or M. This kind of price is interpreted as a percentage to be applied to the entire contract. The percent is negative for a discount price and positive for a markup.

They can be set up for a particular contract type by specifying a value in the Service Type field. If you leave the Service Type field blank, as in this example, the additional charges are available for use on contracts with any service type.
