Do not provide both the VAT date and VAT date code

Error BR-CO-03 EN 16931

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

Mandatory rule: As long as it is violated, the invoice is invalid and will be rejected by validators.
What is wrong

Both ram:TaxPointDate (BT-7) and ram:DueDateTypeCode (BT-8) are provided in the same VAT breakdown. These two values are mutually exclusive.

What the rule means

BT-7 contains the VAT date, while BT-8 contains a VAT date code. Both values must not be used together for an invoice.

Affected fields BT-7 BT-8
Please provide either the VAT date or its code

The invoice contains both a VAT date and a VAT date code. Keep one of these values; you may also leave both out.

What to do
  1. Find the relevant ram:ApplicableTradeTax.
  2. If both are present, remove either ram:TaxPointDate or ram:DueDateTypeCode.
  3. Check the call to SetTaxPointDate(...).
  4. Generate the invoice again and validate it once more.

Technical details

The test passes when exactly one of the two elements is present or when both are absent. It fails when ram:TaxPointDate and ram:DueDateTypeCode are both present.
