XRechnung Background

Create SAP XRechnung – The XRechnung was developed for electronic data exchange with public administrations. It will be mandatory for all contractors in Germany from the end of November 2020. Machine processing offers the federal government, as the recipient of invoices, billions of dollars in savings potential. But the suppliers of public clients face a challenge: How do they create and transfer XRechnungen? Manually via a portal? About an external service provider? Or do you create the XRechnungen directly in your SAP system and transfer them by e-mail?


With the MailCenter platform for digital communication, SAP customers generate XRechnungen directly in the system and transfer them directly to the responsible authority. Simply install our add-on into your SAP system. After a short configuration, the application is ready for use. For ZUGFeRD, you also need a form for the invoice in ADOBE Forms. You simply want to realize your e-calculation in SAP? With MailCenter, we have the right software for you! Do you have any questions? Then contact us. We look forward to seeing you.

Initial situation – Why SAP XRechnung?

The XInvoice specifies a digital format for electronic invoicing. It was determined by the IT Planning Council for the Federal and State Governments. In this way, Germany is creating a uniform format for electronic invoicing. This is in line with the requirements at European level under EU Directive 2014/55/EU. As an electronic invoice, only XRechnung is accepted by all contracting authorities in the public sector. Conventional invoicing by paper or simple PDF is no longer possible. Each country has its own peculiarities and formats.

E-BILL. Gv. AT is the procedure for the transfer of data transmission for the transfer of electronic structured invoices (e-invoices) to public administrations or companies in Austria.

Motivation – electronic invoices directly from SAP

Due to the obligation to use XRechnung, we have developed an extension for XRechnungen and ZUGFeRD for our MailCenter customers. Our goal is the optimal exchange of electronic invoices between business partners and authorities. This solution is fully integrated with SAP ERP. This allows you to create, validate and send invoices according to the German XInvoice format. The creation takes place directly in the course of invoicing with SAP. If you send XIns directly from SAP to your customers, this has the decisive advantages:

  • All data is processed in SAP. This means that you do not have duplicate data storage, media breaks or cumbersome communication channels.
  • Due to the simple configuration, you can make adjustments yourself in case of changes to the standard. As a result, you don’t need programming adjustments or expensive consultants.
  • Little configuration is required. This means that you are fully operational after a short time to send invoices.

What is Peppol?

The Pan-European Public Procurement OnLine (PEPPOL) is an international project. It is used to standardise cross-border, electronically supported public procurement procedures within the European Union.

The aim is to speed up the electronically supported public tendering and procurement process and thus save costs.
PEPPOL supports E-invoicing Directive 2014/55/EU. HOWEVER, PEPPOL is not limited to the exchange of invoices (E-Invoicing) such as ZUGFeRD. It covers the entire electronic procurement process. PEPPOL allows the exchange with all registered partners in the network via a connection. Access is via so-called access points.

How does Peppol work?

The exchange is done via different message types and defined standards. For example, a message type is the invoice. These standards include the Universal Business Language (UBL Standard ISO/IEC) format. The PEPPOL network is used to exchange The UBL documents.

What are the advantages of Peppol?

The maximum size of the XInvoice including the invoice-accompanying systems is 15 megabytes with Peppol and 10 megabytes by e-mail. It is a secure transmission through encrypted communication via AS4, SSL and TLS. No phishing possible. You will receive a shipping confirmation. If you successfully transfer to the Peppol network, you will receive a technical confirmation.

SAP Peppol

As a certified access point provider, we offer the basis for electronic invoicing to authorities according to the secure PEPPOL standard. Since October 2020, munich enterprise software has been a member of the openPeppol community. Thanks to direct authorized Peppol connection and as a certified access point provider, we also offer the transmission of e-invoices via this transmission route.
