How can I submit invoices which, together with their attachments, exceed 15 megabytes?
We are currently working on a technical solution for the transmission of large attachments on the ZRE. More information about the solution on the OZG-RE is available at the FAQs OZG-RE (DE).
It may sometimes be necessary to send supporting attachments separately. In such cases, please contact your invoice recipient to arrange an alternative transmission method for the attachments (e.g. a separate email).
