Additional Discount
This setting is available when editing on the highest Company or
Division level. Use this setting to select which Discount Number to use
for discounts handled through the Discount Calculator.
If Additional Discount is set to Yes, you can view, enter, and calculate additional discount in both the Discount Calculator and Price Guidance. How the additional discount is calculated and stored on the order line depends on the rules for the Discount Model and Discount Number.
The default setting for Additional Discount is No.
