PEPPOL-EN16931-R005: VAT accounting currency code MUST be different from invoice currency code when provided
Peppol BIS Billing 3.0.21 · UBL
Original rule text
[PEPPOL-EN16931-R005]-VAT accounting currency code MUST be different from invoice currency code when provided.
not(normalize-space(text()) = normalize-space(../cbc:DocumentCurrencyCode/text()))PEPPOL-EN16931-R005 is a fatal rule in the format layer of Peppol BIS Billing 3.0.21 · UBL. An invoice that breaks it is rejected.
What this rule requires
The rule applies when cbc:TaxCurrencyCode is present. It requires that the normalized value of cbc:TaxCurrencyCode must not be equal to the normalized value of its sibling cbc:DocumentCurrencyCode (the invoice currency code). Surrounding whitespace is ignored, so values that differ only by whitespace are still considered equal and fail the rule.
How to fix
If the VAT accounting currency is the same as the invoice currency, remove cbc:TaxCurrencyCode. If a separate VAT accounting currency is intended, set cbc:TaxCurrencyCode to a value different from cbc:DocumentCurrencyCode, or correct cbc:DocumentCurrencyCode accordingly.
