Our product includes several reports written in CR XI.  Several of them have date parameters.  For example, a Daily Production report asks the user to enter the date he wants the report for.  The customer, not surprisingly, wants the default value to be whatever yesterday's date was.  The only way I've seen to do that is to have the parameter default to some ridiculous date like '1/1/1900', and the have the select formula check to see if the parameter matches the strange date, and then calculate yesterday's date if it does. 
 
CR lets us write formulas for everything else.  Can't we have a "parameter default formula"?  We'd just enter a default formula of "DateValue(DateAdd("d", -1, CurrentDateTime)), and voila!  Every time the user opens the report, the parameter screen shows yesterday's date!
 
By any wild chance (he says with no hope whatsoever), does CR 2008 offer that feature?

I agree that the ability to default report Parameter Fields (static or dynamic) to an initial value other than blank or a hard coded value would be a most excellent addition to crystal reports.
 
I have a report that I would like to default the prompt to the current date.  That could be done with the use of the CurrentDate function in the Parameter wizard's Default Value field.
 
I also want to defaut a username prompt to the current login user.
 
My ultimate objective is having a user press a button and generate today's report without the user having to think about dates or who they are.
 
Thanks for listening,
Rich
