Adding parameters and filters to the report

Parameters and filters work hand in hand. Adding parameters and creating a filter in a report enables you to create a single report that can be modified whenever your needs change.

To add a parameter to the report

1. In the Field Explorer view, right-click Parameters and click New.

MyParameter is created under the Parameters node.

2. Right-click MyParameter and click Properties.
3. In the Properties pane, enter the following values to their corresponding property name:
• Name: Country
• Type: String
• Prompt Text: Enter country
• Value Range Kind: Discrete

To add a filter to the report

1. In the Crystal Reports editor, switch to the Formulas view.
2. Below Record Filter, type {CUSTOMER.COUNTRY} = {?Country}.

This filter lets you view only the report for the specified country.

To view the report, switch to Preview view in the Crystal Reports editor. When you view the report, a Parameter prompt will ask which country’s report you wish to view.
