Test Commission Calculation Settings

To test the commission calculation settings: Go to the General > Settings section. 

Here, go to the Sales section.

Here, the "Include discounts" option is enabled and is set to adjust the commission by discount percentage.

In the test order's summary, we can see that the discount adjustment is deducting $20 from the sales commission: $200 (sales commission) - $20 (discount adjustment) = $180 (total commission).

The discount adjustment is calculated by the percentage of the discount applied (10%) on the sales commission ($200) which will be: $20.

Note: The commission rate of the affiliate is set to 20%.

Now, go back to the Sales section (in Settings > General) and set the "Include discounts" option to adjust the commission by discount amount.

After setting this up, the commission in the order will be adjusted by the discount amount.

After this, you will have to recalculate the order. To do that go to the Sales > All Sales table. Next, click on the order number > Recalculate. 

In the test order's summary, we can see that the discount adjustment is deducting $100 from the sales commission: $200 (sales commission) - $100 (discount adjustment) = $100 (total commission).

The discount adjustment is calculated by the amount of the discount applied in the order: 10% (discount applied) of $1000 (order subtotal) = $100.

Similarly, different sales settings can be tested by enabling them and reprocessing the order to see how the commission will be calculated.
