With S/4HANA, SAP has taken major steps in the direction of digitization. In addition to improving performance through the new online database HANA, the eponymous ERP system S/4HANA is now also available in the cloud or, as before, on-premise. In addition, the functional scope of the core system has been expanded. FIORI complements the familiar SAP interface in the browser. This simplifies operation, increases user approval and enables platform-independent access via mobile devices.
