Hello,
I need some help to configure my tax procedure TAXTR for a scenario:

We are doing outgoing invoice Domestic for Export.
On the layout, we should have:

VAT Basis 100
VAT 18% 18
Total with VAT 118

There is a stamp on the invoice saying that the VAT is not payable by
the customer because material is for export.

In accounting, I should have the following posting:

Debit CUSTOMER X 100
Credit Sales 100-
Debit VAT in 18
Credit VAT out 18-

How can I define my tax procedure to get this kind of VAT posting?

Thanks
