SAP S-4HANA - Simply Explained

SAP S/4HANA sounds intimidating, yet most companies running SAP ECC have to decide where it lives and how to migrate before the 2027 deadline. This plain-language episode is for IT and business people who need to understand what S/4HANA is, how it connects to Microsoft tools, and where projects usually go wrong.

In this episode

• 00:00 – What SAP S/4HANA actually is
• 01:42 – Why the in-memory database changed everything
• 03:57 – Fiori, the Universal Journal and end-to-end flows
• 06:56 – On premise, private cloud, public cloud or hybrid
• 08:28 – Migration paths and the 2027 deadline
• 10:04 – Keeping the core clean
• 11:00 – Where S/4HANA meets Microsoft
• 12:56 – Honest limits and common mistakes

Key takeaways

• SAP S/4HANA is an ERP system rebuilt on the in-memory, column-based HANA database, which lets analytics and transactions run on one shared copy of the data.
• Every company on SAP ECC must choose a deployment model and a migration path (greenfield, brownfield or bluefield) before mainstream maintenance ends in 2027.
• Keeping a clean core and integrating through Microsoft Fabric, Entra ID and Power Platform connectors pays off in upgrades, while data cleanup and process change are the real cost of migration.

Worth quoting

“S four Hana isn't one product so much as a shared set of processes built on one shared source of data, and the value comes from how tightly those pieces fit together.” – Mirko Peters (06:52)

“Public cloud gives you fewer upgrade headaches and less control, while private cloud and on premise give you more control and more work to carry.” – Mirko Peters (08:08)
