we noticed an anomaly in the VAT Sales and Purchase Register.
We have imported some sales transactions with FBDI External Tax Transaction and then we ran the tax allocation process, after that we generate the report.
We see that the main part of record has Customer Address= 'BRAK', can you explain us why and how to fix it?
