Reverse charge VAT on custom amount discount

John Broers


We're using the Reverse charge for VAT option to not charge certain users for VAT. But when we are setting a custom amount discount on the cart the VAT is showing a negative number. It looks like there is VAT calculated on this discount while it shouldn't. Is there any setting that can fix this?

We're using the cartCmd to add the discount like this: ?CartCmd=setDiscount&OrderDiscount=10. I attached some screenshots to display the problem.

Our Dynamicweb version is 9.17.4
