Report templates are saved as .rpt files. The report template is the "shell" of the report. It contains the report format and shows the list of possible parameters.
Report parameters specify what data to include in the report, and are user-defined. Report parameters are saved .rpx files. Any number of parameter files can be saved for a report template.
Crystal Reports is required to edit or create report templates.

When the template opens, the Properties box for the template is displayed. Parameters must be defined before the report can be run.
