Filters Issue - urgent please!!

Question

Hello Experts,
After checking the DBA guide, I did not find a limit for the number of filter rows that can be inside one filter nor the number of filters a group can have assigned to it (assuming more than one database).
For instance, I have several filters on one database based off a large dimension with approximately 75 "read @IDESC("member")" and I wanted to know what the actual limit on filter rows are since 75 might be approaching that number (we normally have one or two rows).
Also, in a related question, what is the maximum total number of filters (e.g., databases) that a group can have assigned to it? That is, if I have one filter like the above for N databases, and I assign them all to one group for filter access, what's the maximum number than N can represent?
Please suggest.
Thank You,
Sonu

I just went digging through the API and I don't see anything specific about limiting how many filters you can have. I would guess that the limit isn't strictly defined, however, the more you have the more processing has to be done on them. If there is some sort of limit I'd think maybe it's a power of 2 (like 128 or 256). If you want to check, maybe you can setup a quick filter-granting script that creates a hundred or two hundred filters and sees if the system takes it. Of course, hopefully there'd be a better way to dole out permissions than this -- like using a UDA or the DESCENDANTS of some member or something.
