Rule actions allow you to specify what JIRA data you want to insert into your report and where. If you want your rule actions to only be executed if certain conditions are met, you will also need to specify rule conditions.
You can follow these steps to add new actions to an existing rule in your report template.
Navigate to the Templates page.
Click on the Edit template icon next to the template containing the rule you want to add a rule condition to.
You should now be able to see the Edit Template page. Click the row for the rule you want to edit in the Rules section.
Hover over an existing action and click either the Clone or Add new button to add a new action to the rule.
You can click here to find out more about the different types of actions that you can specify in your rules.
Once you have finished, test your report and when you are happy, publish the changes. If there are rule conditions specified, the actions you have specified will only be executed if those conditions are met. If you want your actions to always be executed, or executed if different conditions are satisfied, you will need to create a new rule and specify those actions in that rule.
