Can I automatically set the due date of a parent issue to the maximum due date among all sub tasks?

Andreas Knecht Community Leader Nov 24, 2016

Whenever a sub-task's due date is edited, I'd like to update the parent's due date if the sub-task's due date is later then the current due date of the parent (and all other sub-tasks).

So this automation rule is a bit crazy, but it is *actually* possible to do this.  Here's a screenshot of the rule in action:
Let me break this down:
  • First we have an issue updated trigger
  • Next we have a condition to check that the issue's duedate was updated by checking that {{#changelog.duedate}}{{toString}}{{/changelog.duedate}} is not empty
  • Next we run a JQL condition to check it was a sub-task we edited
  • And then we have a related issues condition that checks all other sub-tasks and parent (excluding the current issue) to see if they all have due dates before the current issue.  So first we lookup siblings and parent using: parent = {{issue.parent.key}} and key != {{issue.key}} OR key = {{issue.parent.key}}
    Then we check that all of them match: duedate is empty OR duedate < '{{#issue.fields.duedate}}format="jqlDate"{{/issue.fields.duedate}}'
  • If that's true, then we edit the parent issue and set its duedate to the due date of the issue that triggered the rule chain using this advanced JSON:

       "fields": {


Here's a screenshot of just the related issues condition as well:
This is a pretty advanced use-case for Automation for JIRA and not quite as simple as we'd like it to be yet! Oct 02, 2018

Does it work also for epics when one of its stories has the due date changed?


Like this:

This is an epic that has its due date set to 10/24


BUT inside of it there is a story whose the due date is 10/25.dueDate_dynamic01.PNG


Can you confirm? Thanks in advance
