BR-CL-06
EN 16931
FATAL
This is a code list rule: a coded field in your invoice uses a value that is not part of the official list for that field (currencies, country codes, VAT categories, unit codes, payment means...).
How to fix it
- Check the exact code against the official list named in the rule text.
- Watch for case and whitespace - codes are case-sensitive (
EUR, noteur). - Common lists: ISO 4217 currencies, ISO 3166-1 countries, UNCL5305 VAT categories, UN/ECE Rec 20 units, UNCL4461 payment means.
Official rule text
Value added tax point date code MUST be coded using a restriction of UNTDID 2005.
