Cascading Dynamic Parameters Do Not Work In Crystal Viewer 2008?

82 Views

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?
