SAP S/4HANA represents the latest SAP product line and will sooner or later replace the Business Suite. However, the current core product SAP ERP is to be further developed and maintained until at least 2025. SAP does not see S/4HANA as a mere further development of SAP ERP, but as a completely new product line that was developed as a strategic response to the challenges of digital change.
All current and future SAP customers are thus faced with the challenge of migrating to S/4 HANA in the coming years.
