Parameter Prompts

[susanna123]

I set up for example: 4 parameter prompts that prompts the user to enter values to filter the return of data.

All my parameters are static parameters and when I hit refresh, i would need to fill in the 4 fields.

Field 1
Field 2
Field 3
Field 4

Is there a case where it's okay to just fill in some but not all the fields.

For example fill in field 1 and 2 but leave 3 and 4 blank and the report still runs fine?

Also, what if the 4 fields are required to be mandatory, is there a way to prompt an error message?

Is this something that needs to be coded or can it be done by setting some true/false values when you edit parameter fields

Feedback is much appreciated. Thks

It depends on your Crystal version - 8, 8.5, 9, 10, 11 or whatever. But basically you get prompted for a value if there is no default value, or if the report is not set to pick them up. (Crystal 11 initially ignored the defaults I had set in Crystal 10 and I had to reset.)

I don't think error messages as such are possible. You can have a section that is normally suppressed and only shows if the parameters don't add up.

Hi,

How do you set it to show the default value or null?

To set a default value for a parameter right click the parameter to get to parameter edit. Under value options, default value:
