Tax on discounts for products

Installed new version on 1.4.10. VAT is calculated on the price before the discount. In many countries, VAT is only due on the discounted product price. Is there a setting that I overlooked to achieve this ?

this problem was discussed multiple times in the forum. Please use the search first before posting a new support thread.
Quick summary: there is no option for it and it’s not possible within InvoicePlane by default. You have to enter discounts as separate items.
