A parameter value is a way of limiting the report data retrieved when you run a report. For example, in a report that displays customer information, you can use parameter values to display sales history for a specific customer, or view the details of specific orders. If a report requires you to enter parameter values, you are prompted to type the value when you generate the report. Specifying parameter values enables you to navigate a report more effectively, and display only the information you need.

If the report requires you to enter parameter values to determine what data to display, you can modify these values to view other data, by choosing Parameters from the main menu. If you choose this option, and parameter values are not needed, a message appears informing you that the report contains no parameters. You learn more about using parameters later in this document.
