Filtering allows you augment the output of your report tasks and templates. There are several ways to filter, including directly within templates and within report tasks or filter cycles.

Note that filters are additive, and may occur at different levels. Because of this, there is a concept of effective filters. For example, if there are filters at the page level and template component level, the effective filters are the union of the page level and component level filters, with the page level filters taking precedence.

Before working with filters, you should take a moment to understand the order of precedence for filters.
