Hi Oleg,
I performed this exercise successfully 1 year ago and need to state that SAP HANA prepares the stage for any next step in regards to Supply Chain Planning. Be it either a tranisition to IBP or "just" a creation of a solid foundation.
You can get an high level insight in some of those topics if you browse through the blog I have crafted.
SAP HANA, S/4 HANA, IBP, cloud, IoT, DevOps, … BINGO!
e.g. the performance figures are the ones we measured before and after the migration. The bandwidth varies between 20 to 80% improvement dependent on the area / functionality.
cheers, Peter
