    Posted: 14 May 2008 at 9:17am

Hello everyone. I have to create a series of reports that have pivot table functionality (the user can select and update the various fields the table shows).

At first I thought a Cross-Tab would be a good way to go, but I've realized that a cross tab is very different from a pivot table, and I don't think it can be used for what I'm trying to do.
 
I know I probably have to use Parameters, but is that the best way? And if so, how would I be able to allow the user to enter a new set of parameters once they've already generated a report?
 
Thanks for the help.

This is going to be a challenge.  It's possible, but not easy, and will likely be tedious to create.

A cross-tab is likely to be key to your solution in some way.  It's just the easiest way to break data down in that fashion.

Your best option is likely to be creating multiple detail sections, each with a cross-tab in a different configuration (assuming you have a relatively small number of possible configurations).  Then, use parameters to suppress all the sections that you don't want to see.

As for changing the parameters, the only way to do that is to refresh the report.  At that point, the user will be prompted as to whether or not they want to change the parameters.

Yes, the Excel interactive pivot tables and charts are nice. I'm trying to do something similar. Keep in mind that I'm relatively new to Crystal and that I'm using CR 2008.
 
My example is displaying computer utilizations for many computers for every hour of every day last month. There are too many computers and too many times to display it all at once, so give the user control to zoom into time periods and computers of interest.
 
I was thinking to get all the data for last month then use parameters to filter the saved data (datetimes and computers) before it is put into a cross-tab and charted.  So users pick and enter parameters, refresh the report, and see new charts and tables.
 
I've prototyped this, but I was using the parameter values to filter the records retrieved into the report; i.e., changing the parameters caused new data to be reselected. Can I use parameters to filter the 'saved data' and not have to be connected to the data source?
I'd like to have users be able to view and interact with the report without having to be connected to the data source and without needing to have Crystal Reports.  Can this be done say with the Report Viewer?
 
I also had the parameters (datetime and computers) dropdowns fixed; I'd like to have the initialized from the retrieved data. How to do this?
 
Hope this helps.
