You use conditions to determine whether:
Agents deliver their content and execute their actions
Actions links (which when clicked run actions) are displayed in dashboard pages
Sections and their content are displayed in dashboard pages
For example, a sales manager wants to deliver a Monthly Sales Report to his direct reports only when sales drop below $2 million. You might create a condition that is based on an analysis that shows sales that are below $2 million and add it to an agent whose delivery content is the Monthly Sales Report. When the condition evaluates to true (that is, the analysis contains rows where sales are below $2 million), the agent is triggered to deliver the Monthly Sales Report.
You can also use a different kind of condition to determine whether action links are enabled in analyses. For information, see "About Conditionally Enabling Actions Added to Analyses".
