E-invoice error explained
For payment by credit transfer (code 58 SEPA credit transfer or 30 credit transfer) the invoice must name the account the buyer pays to: the IBAN, or for non-SEPA accounts the account number (BT-84).
For payment by credit transfer (code 58 SEPA credit transfer or 30 credit transfer) the invoice must name the account the buyer pays to: the IBAN, or for non-SEPA accounts the account number (BT-84). In CII the rule fires when the account block exists but holds neither IBAN nor account number. If the whole block is missing in an XRechnung, you get BR-DE-23-a.
If the Payment means type code (BT-81) means SEPA credit transfer, Local credit transfer or Non-SEPA international credit transfer, the Payment account identifier (BT-84) shall be present.

Enter the IBAN in ram:IBANID inside ram:PayeePartyCreditorFinancialAccount, without spaces. For accounts without an IBAN use ram:ProprietaryID. Check the IBAN first, because BR-DE-19 warns about an invalid IBAN.
