Percent
To activate this field, select Percent in the Discount Type field. Enter the percentage of the discount to apply to this order.
When calculating discounts for an order, the system will apply any line item level discounts that exist to each line. Then it applies the order level discount to the sum of the lines.
Note: If you make
changes to an order after entering a discount, the system will display
a warning message because the discount is based on a percentage of the
Total Price. Therefore, when you make changes to the order, you may want
to update the order discount.
