Here's a question that has stumped everyone I've asked so far. I'll create a simplified example here. For every calculated measure in my cube, I witness this phenomenon. It looks like some kind of crazy rounding error, but I can't figure out why that would be. I'm working with straightforward financial data, so every number has just two decimal places. I'm only summing, not doing division, so the number of decimal places should not change. Nevertheless, this is what I see:
January February March ALL
Revenue: $10.00 $10.00 $10.00 $30.0173519
What on Earth could cause this and how can I fix it? When I'm looking at tens of millions of dollars, I could be over or under by as much as +/-$30. I have financial reports where certain columns are supposed to tie out to zero and they never do. We've lived with it for a while, but it's starting to raise a few eyebrows.
