Discount calculation wrong.

Settings how to calculate discount is set to “Line item”

Result is OK: the Amount is set to Price Per Unit time Quantity and Opportunity Line Amount is set to Amount minus Manual Discount with Tax added.

Settings how to calculate discount is set to “Per unit”

Result is WRONG:

1. The Price Per Unit minus Manual Discount should be € 100, resulting in an Amount of 10 * € 100 = € 1.000. The system calculates € 1.010;


2. Adding a Tax value of € 210 should result in an Opportunity Line Amount of € 1.210 and not € 790;

When set to Line Item, the calculation is/should be like:

Amount = Price per unit * Quantity

Opportunity Line Amount = Amount - (Volume discount * Quantity) - Manual discount + Tax

When set to Unit, the calculation is/should be like:

Amount = (Price per unit - Volume discount) * Quantity Opportunity Line Amount = Amount - ((Volume discount + Manual discount) * Quantity) + Tax
