Professional Authoring vs. Express Authoring in Report Studio

[que5921]

I am new to Cognos and am trying to learn Report Studio without a technical background.  Would you recommend using Express then easing into Professional?  Or should I just jump right in?

I have learned RS before it have the express mode. As I can tell, everytime i have to help someone in express mode, i have real difficulty to achieve everything because i cannot fully access the query of the list or crosstab. If you need to enter particular function like tuple, aggregation, descendants and so on, you will need the professionnal mode to do what you want.

RS express is like analysis studio with more customization to the esthetic at my point of view.

Hope this help..
