Hi,
As long as the planning session is active, you can do a
SELECT * FROM YOUR_SCHEMA_NAME."_SYS_PLE:20150909090339_0652820:DATA"
from hana studio to see the data in the active view of the planning session.
There are methods in ABAP where you can set the active view.
It would relally be interesting to find out if there are any statement to view e.g. a non-active view.
