As far as I know there are 1511.2 and 1503 versions available today and 1605 coming in October - I heard.
I have a few discussions with my peers and SAP folks about how to pick the right version.
There are some say go with the latest version (1511), and as usual some say go with an earlier version because it's stable (this part is not that important for me). For reporting purposes I prefer 1511 with embedded analytics/CDS views etc.
But we also discussed about the customer environment; they are focused on Finance, so some said we should go with 1503, because 1511 has logistic focus and some restrictions on Finance. I was under impression that 1511 has everything that 1503 has + more + better(or am i thinking 1605?). If you know the difference well could you please elaborate on this?
