I am now trying to setup authentication through AD and I am not having much luck. Also, now that I have changed the USER variable to be associated with the LDAP init block I created I am seeing the other init blocks were created by the bi apps implementation failing. Any help would be greatly appreciated. David Dylan,

[nQSError: 59001] Binary logical operation is not permitted on Double operand(s) (S1000) Basically this comes from my drill down report. I have 2 hierarchies on one report, 3 columns --- months, state, measures.. If I drill down from STate ---- lowest, then drill month, things work fine; but if I start with month---week, then drill state down, I will get this error.. I checked the column data types from DB, month is char, week is date, state is char, measure is int SO let me know what you think? appreciate it hello dylan

The year divides evenly into 4 quarters of 13 weeks, or 13 months of 4 weeks, or 2 halves of 26 weeks. If you measure your year in 52 weeks, then it becomes a more eloquent means of counting the days. Can you imagine if bi-weekly and monthly events (like bills & rent & paycheques) all synchronised with one another? It would make accounting so easy that we would require far fewer hours working on our budgets. simple, no? you are perpetuating a common misconception.

I am currently involved in setting up security in OBIEE, and my needs are close to what you describe. Still, I get stuck on the following problem: I wand to be able to filter on one or more brand, depending on the user (or on a group he'd belong to). But if I use a single session variable, I'll be able to store only one brand in it. So it means I should have to set up a session variable for each brand I want to grant the user. I don't think this is very clean, as it would limit the number of brands a user can be granted. Do you have any advice ? thanks. Cedric. Hi Dylan !
