BR-CO-03
Error (blocking) EN 16931 (UBL)EN 16931 (CII)
Official rule text
[BR-CO-03]-Value added tax point date (BT-7) and Value added tax point date code (BT-8) are mutually exclusive.
What it means
You may send the VAT point date as an explicit date (BT-7) or as a code (BT-8), never both. In UBL the pair is cbc:TaxPointDate vs cac:InvoicePeriod/cbc:DescriptionCode, two elements that live far apart in the document - which is exactly why generators emit both without noticing.
How to fix it
Keep either BT-7 (cbc:TaxPointDate) or BT-8 (cac:InvoicePeriod/cbc:DescriptionCode with UNTDID 2005 code 3, 35 or 432) and remove the other.
Business terms involved: BT-7BT-8
🇫🇷 En français
La date d'exigibilité de la TVA se transmet soit en date explicite (BT-7), soit en code (BT-8), jamais les deux. En UBL, la paire est cbc:TaxPointDate contre cac:InvoicePeriod/cbc:DescriptionCode - deux éléments éloignés dans le document, ce qui explique que les générateurs produisent les deux sans s'en rendre compte.
Correction : Gardez soit le BT-7 (cbc:TaxPointDate), soit le BT-8 (cac:InvoicePeriod/cbc:DescriptionCode avec le code UNTDID 2005 : 3, 35 ou 432) et supprimez l'autre.
