Vat tax. problem with built-in calculation rule DATaxBill

[floschaer]

Hello

I want to give a discount for all customers 10% which is shown in the shopping basket.
I realized it with the tax & calculation rule: Pricemodificator before tax for the whole bill (DBTaxBill)
Unfortunately the tax price of the end price is wrong. It keeps the same tax.



in german:

Wenn man eine Rechenregel "Preismodifikator nach Steuer pro Rechnung" festlegt, dann wird die MwSt. beim Totalbetrag nicht angepasst

In your case you must use a rule per product then.

Thanks for your answer I have even tried that, but I want to show the normal prices and only in the basket the price discount.

Or DATaxBill, the reason is that we do not use vattax per bill.

Thanks for your reply which is confusing.
Why do you offer the posibility to choose vattax per bill in the backend when you can't use it anyway???
