As you know that these invoices are belongs to the suppliers which are changed recently from e-invoice to ERS. I could not see this information in any of the below email. Please provide the full history of the issue when sending to hotline for investigation. If you send the part of the information, it could lead to confusion and wrong advice. I have told to you that ERS invoices should be created, once the setup of suppliers completed in ARIBA. In this case, the invoice are created before supplier setup in ARIBA. Hence, the invoices are not routed supplier inbox.
