Your report is only as good as your requirements.
When I first worked with reports and reporting services, I was excited and giddy. Beside my plain old text and T-SQL, I now get to work with some shapes and colors! And look ma, no hands, err, it’s drag and drop!
But the fascination with colors, drilldowns, drillthroughs, what-have-yous fade away as quickly as that drag and drop. You realize fast that – although managers typically like the pie charts, the drill downs, the colored legends – if any number, or any minor thing for that matter, is not “right”, the whole report is not right, and all your work really goes down the drain.
Sometimes, it’s not because the report is “completely wrong”.
