Linking Start and Due Date of Child Issues to Parent

[Daniel Welch]

Hi there, 

Trying to automatically set the start and due date of a parent based on the earliest and latest date of child issues. Can you point me in the direction of an answer please?

Hi @Daniel Welch -- Welcome to the Atlassian Community!

If you search this community, you will find several posts for this same question and different solution approaches.

One way to do this is with automation rules; the specifics depend upon when / how accurately you want the parent updated.

For example, let's assume you want a parent Epic updated when the Start Date or Due Date changes in a child issue.  The rule could trigger on a change to the date field(s), use the Lookup Issues action to gather the other children, and then find the correct values to update the Epic:

{{lookupIssues.Start date.min}} and {{lookupIssues.duedate.max}}

Additional rules could trigger on adding / removing issues to the Epic, manual tampering with the Epic fields, etc.

To get you started on creating your rule(s), please refer to these documentation and example sources:
