Having been at TechED Las Vegas and Barcelona I really must say that the interest into S/4HANA is overwhelming. I had good discussion with customers and partners and it can be clearly seen that knowledge and understanding of S/4HANA is increasing. The focus of the inquiries is increasingly pointing towards adoption. Consequently the booths were well frequented and S/4HANA sessions were often sold out and even overbooked. Therefore it is good that many have been recorded and are available online. Enjoy in case you did not get a chance on site.
There were some great other sessions from Stefan Elfner, Wieland Schreiner, Sven Denecken on S/4HANA which together with mine will give you a good overview on S/4HANA
