I re-did my work, see new version below.
This is an edit of my original question
This time i have screen shot my connections in studio. Same order as above.
I can see the two ways of accessing the SYSTEMDB via the multi-tenant yields the same results, however, as you can see with the old way, it still gives different results. The older way does not have the 5 "SYS_..." Schemas. How comes as we are still using SYSTEM user and there is only one system therefore one SYSTEMDB (as this is a HANA 2.0 install). I was expecting the older connection to still be able to see everything including the 5 "SYS_..." Schemas.
Am I making myself clear? Do you see what I mean ?
