S/4 HANA System offers new features and the transition from SAP ECC to S/4 is for many companies still in progress or under planning. Question is: What is S/4 and what makes this system so special? What kind of set up( cloud private edition or on Premise) would be better for my company? Is this only a new System with old transaction in web based Fiori or is there something more? What are benefits for my company with S/4? Further aspects you can find in my blog.
