If "Payment means type code" (BT-81) contains a code for credit transfer (30, 58), BG-18 and BG-19 shall not be provided.
The payment means code says credit transfer (30 or 58), but the invoice also carries PAYMENT CARD INFORMATION (BG-18) and DIRECT DEBIT (BG-19). Germany allows exactly one payment method group per invoice.
Delete PAYMENT CARD INFORMATION (BG-18) and DIRECT DEBIT (BG-19) and keep only CREDIT TRANSFER (BG-17). 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.
