Hi,
I am not that familiar with Access db,I think you can create a view or Stored Proc in Access and then change the date parameter in them.Or else
Create a Prompt in Crystal Which accepts the Date as parameter and generate different reports .
I am still not clear with this para in your post
So far, the only thing I've been able to come up with is to create a report with my driving query, then open it and do a Save As to create the other queries I need. That really seems like the long way around the barn because then I'll need to change the date in each individual report.
cheers
Rahul
