Appreciate for your quick reply. I agree with the power brought by SSAS but just wondering the low marketshare by SSAS. Maybe it is because its dashboard tool, Excel and SSRS, do not provide funcy features, like others. But I think you are right, Excel could provide a dynamic report by its user (users can manipulate what they want to see). I am pretty interested in your story on improving sales using cubes. Maybe you can share your story of how the factor was detected from cubes some day. Thanks again for your inputs, GSquared.
