Water Fall Chart drill-through is not enabled on Break Down Field

Hi all,

We've got the feednack from PG, that it's by design.

"Yes this is by design. This is because the identity of the breakdown fields is more complicated than ‘column = value’ which drillthrough supported at the time (not sure if that limitation is lifted now or not). The identity of the breakdown field is ‘category in [value1, value2] and breakdown = value’. So in the example below if I click on ‘Buena Vista’, then identity is ‘Content rating is PG-13 or R and Studio is Buena Vista’."
