Thanks for the quick reply.
Before posting here, I had already seen that SAP note, however, I was not shure if I was in the right place and if the options were doable. That confirms it 
Some forums also indicate that one way to do it is to load into SAP HANA different tables with different sizes to see how much memory they occupy and then calculate the racio. Is this correct?
