Parameter Validation in Crystal Reports
Posted on 2004-09-16
Is there a way we could validate the parameter values in Crystal report. For example one of the reports I have takes the start date and end date as parameters. After the user enters the start date and end date and before runnign the query is there way I could check if the end date is less than the start date.
I would like to do this
Take user parametrs
if end_date < start_date
prompt the user to enter valid parameters
go ahead and execute the query.
