Thanks Harshal for this knowledge,
From what i have gathered HANA is an in-memory database application meaning i can opt to install SAP B1 on Hana or MS sql but the former is very expensive especially if i opt for on-premise, could it be less costly if i opt to install B1 on the cloud , which versions of B1 are supported on the cloud(HANA), am aware of the long term cost benefit of cloud hosted apps and i have ready that SAP are driving all their applications to Hana i better prepare earlier.
With Regard to R3 what is the main difference between R3 and B1
