Hi Ajay Raman,
Before I explain further my thoughts, could you please confirm that you want to display the count of "tickets" not approved?
Tickets - count & the filter on "No" not approved may have confused me.
Thanks for your time.
I believe you are trying to use Measure names as an action filter and that is not supported. You could however create each column as it's own measure. Worse case, you could try using a multi-axis crosstab to create a view with each measure on it's own: multiple axis crosstab | Drawing with Numbers
