If "Payment means type code" (BT-81) contains a code for direct debit (59), BG-17 and BG-18 shall not be provided.
The payment means code says direct debit (59), but the invoice also carries CREDIT TRANSFER (BG-17) and PAYMENT CARD INFORMATION (BG-18). Germany allows exactly one payment method group per invoice.
Delete CREDIT TRANSFER (BG-17) and PAYMENT CARD INFORMATION (BG-18) and keep only DIRECT DEBIT (BG-19). If you genuinely offer more than one way to pay, that has to be agreed outside the invoice — the structured document names a single method.
