Hour 12. Implementing Parameters for Dynamic Reporting

A common goal of report design is to provide a single report that can service very specific reporting requirements, yet also accommodate a large audience of business users. Parameter fields allow you to satisfy this requirement and provide three primary benefits:

• Additional level of interactivity for business users when viewing reports a sales report can prompt the business user for her specific district or territory.

• Ability to segment reports in many different ways to reduce the number of reports necessary to service the demands of the business users a sales report can be segmented by district to service the needs all district-level business users with one report.

• Greater control over the report query for administrators by filtering the report results to include only the selected parameter value(s) a sales report can be filtered to include only data for the appropriate district. This also includes the ability to constraint the report query to avoid including excess or sensitive data.

In this hour, we will take a closer look at the value of using parameters in your reports, as well as how parameter fields can be created and implemented. Like many of the Crystal Reports application features, working with report parameters is very logical but requires some working knowledge of the mechanics necessary to apply these items to create effective reports.

In this hour, we will cover the following topics:

• Understanding the value of parameters

• Creating and implementing parameter fields

• Using parameters with Record Selections
