BR-CO-03

Value added tax point date (BT-7) and Value added tax point date code (BT-8) are mutually exclusive.

What does this rule mean?

The VAT point date (BT-7) and the VAT point date code (BT-8) are both present.

Both describe the same tax point in two ways — they are mutually exclusive.

BT-7
Value added tax point date
BT-8
VAT point date code
Official rule message (standard)

Value added tax point date (BT-7) and Value added tax point date code (BT-8) are mutually exclusive.

Where the rule applies

Syntax: CII · UBL

The same rule, expressed twice: UBL and CII name the same fields with different paths. Running a CII file against the UBL rules is why you get errors that mean nothing.

UBL

  • /ubl:Invoice | /cn:CreditNote

CII

  • //ram:ApplicableHeaderTradeSettlement/ram:ApplicableTradeTax

Technical test

The rule passes when this Schematron expression holds true:

((//ram:TaxPointDate) and not(//ram:DueDateTypeCode)) or (not (//ram:TaxPointDate) and (//ram:DueDateTypeCode)) or (not (//ram:TaxPointDate) and not (//ram:DueDateTypeCode))

How to fix it

Touches amounts, VAT or IBAN. We never change these automatically — correct them in your source data.

Provide either the date (BT-7) or the code (BT-8), not both.

Correct the affected entry in your XML, then re-check the invoice. Validation runs locally in your browser — your file never leaves your machine.
