When report parameters are used how data is filtered?

This includes filtering after the source query has come back – on a data region (like the Tablix), or a data grouping.

What is a parameter in a report?

Parameters are one of the built-in collections that you can include in an expression in a report. Because expressions are used to define values throughout a report definition, you can use parameters to control report appearance or to pass values to related subreports or reports that also use parameters.

Queries retrieve rows and columns from tables. After you run a query, you can further limit the number of items shown in the datasheet by applying filters. Filters are a good choice when you want to temporarily limit the query results without going into Design View to edit your query.
