Discount after tax but the tax need to be lessened as well

A screenshot of the checkout that shows the figures that are wrong. It is hard to guess, since my figures all seem to show correctly

Okay, I did some testing and it seems that using DATax as the normal discount and VatTax as the tax per product calculates the right Vat per product with discount code.

OK, nice to hear that this is all fine, what is not calculated correctly ?

No everything works great in the end. I think I used "Tax" before instead of VatTax, I think thats where the problem was.

Ok, I found the issue.

When I change the Tax to VatTax the price calculation is not working right. So if I am calculating the cost price again with VatTax instaed of Tax, the actual price is wrong. But when I use Tax to set the final price, and then change it to VatTax in the calculation rules, the price stays correct but when I try to calculate the cost price again it's not working correctly.

EDIT: Figured it out. When using VatTax the calculation is not done correctly in combination with DATax, when in the article admin page using the check Calculate Final Price. When you dont use that feature and calculate it by hand (using Cost price) the pricing goes correctly. So I think this is a core issue.

Soooo, this is an admin calculation problem ?
Any screenshots please ?

Yes. These are the rules:



Multiple discounts from a fixed price (5, 10, 15, 20)

Then at product settings this is the good price:



When I try to calculate the cost price with the checkmark:



When I just calculate the cost price myself so that the final price is correct then it works. But calculating the cost price for me inputting the final price is not working correctly. It probably calculates the discount in wrong.
