CodiceDestinatario '0000000' ammesso solo con FPR12

What it means

The wildcard recipient code 0000000 is only allowed for private-recipient transmissions (FormatoTrasmissione=FPR12), not for FPA12.

How to fix it

For FPR12 keep 0000000 and supply PECDestinatario. For a PA, use the real 6-character IPA office code instead.
