PEPPOL-EN16931-CL001

Validation message

Mime code must be according to subset of IANA code list.

Explanation

PEPPOL BIS Billing 3.0 restricts attachment MIME types to a subset of the IANA list — e.g., application/pdf, image/png, application/xml, text/csv.

How to fix

Use a PEPPOL-permitted MIME type. (Typically a software-side issue, not user input — raise this with your invoicing software vendor; if you're receiving the invoice, ask the sender to address it with theirs.)
