Hi - cds newbie here.
I was trying to create an extended view, and this works. However, I then found that when I query it, it appears as if the underlying view is being queried:

Then, I tried to create a new cds view to use the extended view in the FROM clause, but that also appears to be disallowed.

So my question is: how can we use an extended view? The fact that you cannot use and extended view itself in another cds view's from clause seems like a pretty hard reason not to even bother - or is there?
thanks in advance,
