Hi,
I am working on a basic setup of Tax Calculation to learn how to use it. To make my test easier I only use customer free text invoice process.
My goal is to root VAT Number, Tax item group and tax group according to the delivery address country code which we can find in the free text header field:

To perform this, I setup the RCS configuration as follow:








In Finance:


RCS and Finance are synchronized, I get tax code, tax group and tax item group in Finance. But now when I try to create a customer free text invoice nothing happens:
The only thing new is the “override sales tax” button I used to put TG.RCS and ITG.RCS tax group :

The delivery address is set to BGR :

Which must trigger the rules I set in RCS.
If I look to the tax button I must have another VAT ID than those display in this screen :
RCS Rules:

Results in Finance:

I’m probably missing something here, but I cannot figure out what.
