Filters

Many actions allow you to create a filter to more narrowly define the conditions by which the action is executed or to control the data resulting from the action.

• A pre-process filter allows you to limit the data affected by an action. For example, the Filter in the Adjustment transform can be used to limit the rows affected by the adjustment to those rows that have particular characteristics.
• A post-process filter allows you to narrow the results of an action to specific outputs. For example, the Post Aggregation Filter in the Aggregation transform can be used to limit your results to rows with a total aggregate that exceeds a defined value.

Filters are defined by building Expressions in the action’s configuration.
