E-invoice error explained
An XRechnung must state how it is paid.
An XRechnung must state how it is paid. It needs the payment instructions group (BG-16) with at least the payment means code (BT-81). Depending on the code, more data is needed: the bank account for a transfer (BR-DE-23), card data for a card payment (BR-DE-24), mandate data for a direct debit (BR-DE-25). The rule also applies to credit notes and invoices that are already paid.
An invoice (INVOICE) must contain information on "PAYMENT INSTRUCTIONS" (BG-16).

</ram:ApplicableHeaderTradeSettlement>Sales / Project Operations: Sales and Project Operations have no e-invoice output out of the box. In the WBS Invoice Accelerator for Dynamics 365 the bank details come from the brand profile (IBAN, BIC). With an IBAN there, the Accelerator writes code 58 with the IBAN and BIC. Without an IBAN the e-invoice has no payment instructions and BR-DE-1 fails.
Business Central: Fill IBAN, SWIFT Code and Bank Name on the Company Information page, Payments FastTab. Also check the Payment Method Code on the sales document.
Finance: Under Organization administration > Organizations > Legal entities, Bank account information FastTab, the Bank account field must point to a bank account with a valid IBAN.
