BR-05
The invoice has no currency code (BT-5).
ErrorEN 16931UBLCII
Why it happens
The document currency is missing, or given as a symbol or name instead of a code.
How to fix it
Set BT-5 — cbc:DocumentCurrencyCode in UBL, ram:InvoiceCurrencyCode in CII — to an ISO 4217 three-letter code such as EUR or GBP. '€' and 'Euro' are not valid values.
