## FAQ

### Quando usare BT-22 invece di campi strutturati?
Usa BT-22 per informazioni non rappresentabili in campi strutturati (istruzioni consegna, condizioni speciali, disclaimer, contatti aggiuntivi). Quando esiste un campo dedicato, preferisci quello (es. BT-20 per termini di pagamento).

### Posso inserire più note fattura?
Sì, BT-22 ha cardinalità 0..n: puoi inserire più note. Ogni nota può essere categorizzata con BT-21 per facilitarne organizzazione ed elaborazione.

### Che relazione c'è tra BT-21 e BT-22?
BT-21 è un codice (di solito a 3 caratteri) che categorizza il contenuto della nota BT-22 (es. AAI info generali, PMT note pagamento, DEL istruzioni consegna). È opzionale ma aiuta l'automazione.

### Ci sono restrizioni su cosa inserire nelle note?
Evita contraddizioni con i dati strutturati, inserisci solo informazioni pertinenti, rispetta la lunghezza massima, garantisci la compliance e evita dati personali sensibili salvo necessità di fatturazione.

### Le note possono contenere caratteri speciali o più lingue?
Sì, BT-22 supporta UTF-8 e quindi caratteri speciali e più lingue. Assicurati che i sistemi a valle gestiscano correttamente la codifica.

### Lo Skonto va indicato in BT-22 o BT-20?
Le condizioni di Skonto dovrebbero andare principalmente in BT-20 (condizioni di pagamento). Usa BT-22 solo per contesto aggiuntivo o chiarimenti non esprimibili in BT-20.

### Come gestisce le note la PA tedesca?
Le autorità possono elaborare note XRechnung, ma le informazioni critiche dovrebbero stare in campi strutturati quando possibile. Spesso si usano per riferimenti di compliance o info progetto.

### Posso usare le note per contenuti marketing?
Tecnicamente possibile, ma sconsigliato: le note dovrebbero restare pertinenti alla fattura. Contenuti marketing possono essere inappropriati e creare problemi di compliance. Mantieni note professionali e specifiche.
