I guess the more questions there are on topics I know zilch about the sooner I will get around to learning something about SSAS. So I definitely welcome questions like this one, although it took me a lot of burrowing through MSDN and trying to understand new things to discover the answer. So a really good question.

One thing I noticed was that MSDN is a terrible source for information on this - I couldn't find anything that directly answerd the question. I was quite hard to stitch the varions clues together and come up with teh correct result. I hate it when software has documentation which doesn't provide a decent conceptual model which woul include things like this. So thanks for the reference in the explanation to the Kejser and Lee document - that will help fill the gap for me (and probably ensure that I continue to have more to do than I have time for, as I suspect it will be a long read).
