Responses of Senders can contain useful additional information.

IMR and MLR Concept and Use

MLR and IMR files are optional messages, they can be returned by the receivers of your invoices and credit notes. The main volume will be IMR, as MLR is an older standard and IMR is the promoted variant. The file contains the references of the sender and the receiver, as well as the invoice number.

So you can parse the relevant information of the MLR and IMR and store it in your application.
