How to set Due Date once All child tickets have a status of "Done"

[Pete Jaworski]

I want to create an automation rule where:

User Story

1. When subtask = "Done" move parent (User Story) to "Done"
2. When ALL subtasks move to "Done", then Update User Story "Due Date" to current date.

Epic:

1. When user story = "Done" move parent (Epic) to "Done"
2. When ALL user stories move to "Done", then update Epic "Due Date" to current date.

Hi Pete,

Take a look at this sample rule and give yours a try. Let us know how we can help.

This is great! Thanks @John Funk . What about the Due Date? This is what I am most interested in.

Once ALL the child tickets move to "Done", then I want the Epic's Due date to update as the "end date (current date)"

Sure, if you share your rule, then we can discuss what to add - that will be easier.

Thanks @John Funk - Here is a screenshot. I basically want to capture the due date on the parent, when all the subtask/child tickets are moved to "DONE".

Questions.

1. How do I ensure that the DUE DATE doesn't keep updating each time a subtask/child task moves into the "DONE' status. They could be moving to the "DONE" status at different times. I want the DUE DATE when ALL the subtasks/child tickets are moved to DONE.
2. Do I add the DUE DATE rule as a separate branch, or do I incorporate it to the Transition Status rule above?

Hey Pete - so sorry for the delay, I have been very busy lately. 

I would add a Condition to check if the Issue Type = Sub-task (before the Edit Issue)

Then add a branch after the condition for Parent

Add Condition to check that all of the children are Done

Then move the Edit issue under the branch. 

See the example here:
