BG-17Credit transferBT-84Payment account identifier
Official rule text
[BR-50] A Payment account identifier (BT-84) shall be present if Credit transfer (BG-17) information is provided in the Invoice.
Why this error occurs
The value is present but does not match the required pattern: wrong date format, an IBAN with a wrong check digit, an e-mail address without a valid structure, a URL without scheme, or a text with forbidden characters.
How to fix it
Correct the value so it matches the format named in the rule: dates as YYYY-MM-DD in UBL and YYYYMMDD with format="102" in CII, IBANs without spaces and with a valid checksum, e-mail addresses with exactly one @, URLs starting with http:// or https://.
