S/4HANA is SAP's latest ERP product that runs on the HANA database. There are two editions, on-premise and cloud, with the cloud edition receiving quarterly updates and on-premise getting annual upgrades. S/4HANA versions are numbered based on the year and month of release. The on-premise edition also receives feature pack and support pack updates throughout its lifecycle. HANA and ECC also have regular version release cycles with varying levels of support. NetWeaver and FIORI also progress through different version releases.
