While not answering your question, I just wanted to share my point of view on what you say.

It's true that there are many open questions and the community is tiny, not because answers aren't given but mainly because a large number of users just come to get an immediate and direct answer to a question, or even worse somebody doing their job for free. Without really caring about learning how and why the tool works and with absolute no plan of being part of a community. This is why a large number of thread are never closed and abandoned by users: there are many taking without giving.

A community is only as good as the members composing it, all we can do is to try to play the "community" game at the best (and if you look at the community spaces you will see that's a ongoing topic for years), and build a community.

Going back to your thread, I will be honest: I opened it, read it, closed it. Why? Because there were too many blanks to fill, with not enough info provided.

As I look at the forum while doing various other things, if a thread requires me to spend time to just figure out what the OP is trying to ask because there are only 2 sentences and nothing else, I just don't feel like doing the double job: first decode the question and fill all the blanks and picturing what the use case / example is, and after guessing an answer. I'm not saying that's the case for everybody, but that's how I deal with this community: more than happy to help when I can, but it works in both directions. When somebody make an effort to write a complete thread, I will try to help if I can. If the thread just leave me with more questions about what is asked than answers, I move to something else.

With all that: welcome to the Oracle Analytics community, and hopefully your journey with OBIEE will go well.
