Chinese VAT invoices have a couple of different requirements than other invoices. Even though they have their own classification category, they use the same Validation form as regular invoices, but with a few differences.

Invoice CN documents have two additional fields that do not appear when a document is classified as an Invoice.

1. Invoice Code CN

2. Password CN

Other than these minor differences, both document types are validated in the same way.

If you are processing a document that should have the above fields but they are missing, reject the document by selecting the [CHN] Document is a Chinese VAT document rejection reason. This sends the document back so that it is re-extracted and the above fields are included.
