Cascading Dynamic Parameters Do Not Work In Crystal Viewer 2008?

Question

I have generated a report with Crystal Reports 2008 that uses a dynamic cascading parameter. I work in waste management and the report I create in Crystal is used as a "template" with the tonnages collected from all of our customers. Our less technically minded employees can then open this report with Crystal Reports Viewer 2008, use the drop down menus to select only the customer they need a report for and then export this to PDF for delivery.
The report as designed works perfectly in Crystal Reports, but the parameter does not work in Crystal Viewer.
Some of our customers have more than one physical location that we service. The cascading dynamic parameter in my report allows you to select the customer name, and then it only shows the locations linked to that customer, so the end user can select only the relevant location(s) for the report. The cascading parameter is dynamic and allows multiple selections, and is linked to a Saved Data formula. The report is saved with the data.
When the report is opened in Viewer, one of two things happens. If the report is saved in Crystal Reports and a specific customer/location is selected, then ONLY those selected customer/locations are available in the Viewer. If ALL the customers/locations are selected in Crystal Reports and saved, then in the Viewer they are all available, but selecting one customer does NOT narrow down the locations (i.e. it does not "cascade") and instead ALL of the locations are available even if they do not apply to the customer.
If I use a single dynamic parameter and select ALL of the customers (for example), then when this is opened in Crystal Viewer all of the customers are available from the parameters drop down and the report works fine. As soon as this is tried with a cascading parameter however, Crystal Viewer falls down.
Does anyone know of a workaround to this or if there is something I am doing wrong?

Answer 1

I am using the free Crystal Report 2008 Viewer along with designing reports with Crytal Reports ver 12.3. With a test file from SAP called "Interactive Parameters", the parameter feature works to refresh the report. The parameters that are supplied in the sample report work with Viewer. They show up under the parameter list in the parameter side panel in Viewer and are available to make record selections. When I add a parameter to the sample report in Crystal 2008 and then view the report in Viewer, my parameters are unavalable for record selection while the original parameters remain available. Futher, my parameters are displayed under a section called "Current Data Set" in the Parameter side panel, while the selectable parameters are displayed under the "Parameter" section in the parameter side panel. There must be a setting that is treating the parameters I create differently form the parameters created in the original sample report. Any help would be appreciated.
