Prompts for parameterized groups

Got a report that gives the user a Group by parameter with two possible values - Customer and Country. 开发者_运维问答If user selects Customers then the report groups on Customers else on Country if that is the user selection. I want to create two parameters Customer and Country for filtering reports. I want to structure the report in a way that Customer parameter shows up only when Group by is Customers, similarly for Country - prompt only when group by is country. Both the parameters should not show up at the same time as that will confuse the user. Thanks in advance

I don't think you can have optionally available parameters in Crystal, unless this is a new feature in XI onwards.

An alternative approach would be (in addition to your group by parameter) to create a second parameter with a relatively generic name - something like "group selection values" - and select customer values by this second parameter where Customers is the selected grouping option, otherwise select country values by this second parameter.
