Natura/AliquotaIVA incoerente con il riepilogo (riga vs riepilogo)

What it means

A detail line declares a Natura/AliquotaIVA combination for which there is no matching DatiRiepilogo block (or vice-versa). Every distinct (AliquotaIVA, Natura) pair used on the lines must have its own summary block.

How to fix it

For each distinct (AliquotaIVA, Natura) used across DettaglioLinee, add a DatiRiepilogo block with the same AliquotaIVA and Natura, the summed ImponibileImporto and the computed Imposta.
