I need to automatically transitions a subtask to a status, when its parent task transitions

[Heba Rezk]

I have two workflows, one for parent level tasks and stories, and the second is for development sub-tasks

I need a sub-task to transitions automatically to a specific status, when its parent level issue moves.

i could not do it with post functions, and i don't need any Add-on for it

Hi Heba,

Welcome to Atlassian Community!
For a ticket to automatically change status, it will be necessary to use an add-on for that, since Jira Software doesn't have built-in automation and Jira Service Desk, even having built-in automation, there are no triggers to change sub-tasks status.

I was able to make this work by using the add-on Automation for Jira. There is a free version that you can use to test and check if it works for your environment.
- Automation for Jira - Cloud Lite
- Automation for Jira

Here is an example that worked, in this case when the parent transitioned to any status, the sub-tasks were transitioned to "Done":

Hope this helps!

Angélica
