Understanding the Value of Parameters

By using parameter fields that enable business users to select from a list of one or more parameter field values (such as district, country, or account type), you can make reports more valuable for the business users while limiting the volume of data that the report retrieves. For example, a sales report is likely to be more valuable for a sales professional if it allows him to select his specific territory or district, while the report runs more efficiently because it retrieves only the desired data and not an unnecessarily large data set. Parameter fields can prompt users for a variety of information that can be used in a number of flexible ways within reports—good examples include controlling the sort order, grouping order, record selection (filter), report title and descriptions, report language, alerting thresholds, formula inputs, and so on.

Parameter fields prompt report users to enter information by presenting a question that the user must answer before the report is executed. The information that the user enters determines what appears in the resulting report and also how that report is formatted and presented.
