How to update parent story's original estimate with sum of subtasks in team-managed project?

[Anna Laptyuhova]

Hi community,

I'm trying to roll up subtask original estimates to the parent story automatically in a team-managed Jira project.

What I've already tried:

1. Edit work item → Additional fields JSON

json

{ "fields": { "timeoriginalestimate": ... } }

Result: field ignored — timeoriginalestimate not available in team-managed

2. Edit work item → timetracking JSON

json

{ "fields": { "timetracking": { "originalEstimate": "..." } } }

Result: edits the subtask itself, not the parent — no "Parent of trigger work item" option in team-managed dropdown

3. Send web request PUT to REST API

https://mysite.atlassian.net/rest/api/3/issue/{{triggerIssue.parent.key}}

Result: 404 — smart value doesn't resolve in URL field

What I need:
When a subtask's original estimate is updated → calculate sum of all sibling subtasks' original estimates → write total to parent story's original estimate field → visible in backlog without entering each story.

Questions:

• What is the correct smart value for parent issue key in Send web request URL?
• Is there any other approach (branch, lookup, etc.) that works in team-managed?
• Does triggerIssue.parent.subtasks.originalEstimateSeconds.sum work in team-managed at all?

Thanks!

Hi @Anna Laptyuhova 

Welcome to the community.

Whenever you ask for help with an Automation Rule it will help us to help you if you provide:

1. what type of project is this (e.g., company-managed, team-managed, etc.), 

2. images that show your complete rule.

3. images showing the details of any relevant actions/conditions/branches.

4. images showing the Audit Log details for the rule execution.

5. Explain where the issue is.

These questions are not for not willing to help, but to have community members understand on how automation works.

NOTE, you will need a branch to the parent, as you trigger the rule on the sub-taks it needs to branch out to the parent.

{{issue.timeOriginalEstimate}} is the smart value for the field Original Estimate

Hi @Marc -Devoteam- 

FYI -- that linked question you provided is for Jira Data Center automation, not for Cloud (which this question appears to be).

And for Cloud, I do not believe the {{issue.subtasks}} smart value contains all of the fields due to just-in-time read access, timing problems, etc.  Thus, a Lookup Work Items action must be used with JQL to gather the subtasks' data for the parent, and then sum with:

{{lookupIssues.timetracking.originalEstimateSeconds.sum|0}}

Then add the units of measure for seconds when updating the parent.

Kind regards,
Bill
