I fall under the VAT exemption rule and have sold something in Lithuania to an institution that is also exempted from VAT. Every time I submit the ic listing, I get this error message: Your tax regime does not state that you may enter the codes ‘T’ and ‘L’. I try to enter this manually and via an xml file that Dexter creates automatically.
From the other questions, I can see that other people are having this problem too. Is there a solution for this here yet?
