Custom fields and Taxes/Calculation Rules

[EvanGR]

Hello,

I am creating a new Shopper Group, let's call it "Gold Customers"

I create a new Tax & Calculation Rule for this group, which offers a 10% discount to all prices.
Type of Arithmetic Operation: DATax
Math Operation: -8%

It works fine, until we get into the custom fields that affect pricing.
In that case, the prices in the custom fields are not affected by the tax rules.
e.g. If a custom field adds +50 euros to the product, it will do so for Gold Customers as well.

Is this the way it's supposed to work?

Do you try breakdesign custom field?

We use 8 years, I think from this reason...
