Summary

Rollup story points to Epic level, if story points on a subtask of a child story is updated

Environment

Can be used in both cloud and server environment.

Solution

Basically, this rule will help you in summing up the story points from Sub-task(child) to Story(Parent) to Epic(Top level issue-hierarchy). In simple terms, whenever you update the story points in the sub-task, they get updated in their Story(Parent) and the Epic level too.

Note: In the rule details page, make sure you tick mark the checkbox for Check to allow other rule actions to trigger this rule. Only enable this if you need this rule to execute in response to another rule.
