My users have asked me for a report that would display grouped data in two different formats: by month or by week. The catch is that they want to be able to choose between the two options at runtime. I currently have the data grouped by date, then by project number, with the detail records hidden and available in a drill-down. They would want the top-level data to look something like the example below.
July 2008 $100,000
Week 29 $45,000
My first approach was going to be to create a parameter the users could set, then change the group display option to print either by week or by month depending on that value. But I can't find anywhere to put the formula!
Am I missing something obvious? Is there a better way to approach the problem? I really don't want to create two separate versions of the same report over a formatting difference.
