I am using a cascading filter for a 3 level hierarchy. The rationale for a cascading is that my hierarchy has a grand total of 5M row, with just a few hundred per level. My hope was that a search could run per level instead of across the 5M rows, thus speeding it up (well, it speeds up but it’s really not fast. At least now it completes).
My issue is that I have to fill up all 3 levels of hierarchy. I apparently cannot just select the top level.
I notice that because the query sent to my DB only uses the default data (defined in the data cube - the filter is bound to a bridge parameter) if I do not select something in all 3 levels.
I could not find a way to allow none
for the second and third level. Is it at all possible? Or am I stuck with the non-cascading filter?
