PEPPOL-EN16931-CL006
Validation message
Explanation
The invoice period description code must come from UNCL 2005 version D.16B.
How to fix
Use a code from UNCL 2005 D.16B. (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.)
