Thank you so much for your responses to my question.
I am sorry I think I was not very clear with my question.
I was wondering if It was possible to design reports just the way it is possible with Crystal and Access. I can define my header, my footer, and my detail sections for all my groupings if any, and choose present my details information in any position on my report. That way, I could have a complete control over my data presentation for my reports. Another example, maybe I want to create a text field that would for instance display the number of records ( using the Sum function ). I can even make it visible or invisible. These are the kind abilities I wish to be able to have with Cognos. Is it possible???
From a programmer point of view, it would be nice to have that much flexibility.
