FatturaPAError

A line (DettaglioLinee) or VAT summary (DatiRiepilogo) has AliquotaIVA 0.00 but no Natura code. Every 0 % item must state why VAT is not applied with a Natura code N1–N7 (e.g. N2.2 non soggette, N3.2 non imponibili cessioni intracomunitarie, N4 esenti, N6.x inversione contabile); the sender must add it on the line and in the matching DatiRiepilogo.
