I am not sure if this is the right forum but i thought i could start here. Which is the best tool within cognos for what if analysis. I have 2 variables, A & B. i want to see how B would change when i change A. Thanks
I'm not going to pretend to be independent, since I've worked with the tool for 15 years, but I would suggest using TM1. Most Cognos tools are readonly, which is kind of a showstopper for doing whatif modelling. TM1 is readwrite (though not via BI), so you can use Perspectives or TM1 Web to input your whatif changes and any of the the delivery tools to view the effect. If you have a large and/or complex model the recalculation will take some time.
