Linking parent and subtask so certain custom fields updated on the parent will update the subtask.

[Linda H]

We are moving to Jira 7.6.  I want to create subtasks with custom fields that are linked to the parent so that if I change data in the parent it changes data in the subtask.

Is there a post function that does this?  I have looked at a couple but cannot get them to work, so I'm guessing I am trying the wrong one or missing something. 

I'm using the post function on the create transition for the subtask when creating a specific subtask issue type, so I know that the post function has to come after "Creates the issue originally".  I thought Linked Transition (JSU) would be the logical choice, but it is not working.   Yes, the fields I want to link do have data in the parent task, but are not flowing to the subtask.

Hi,

If you change things in the parent task, and use post-function, it will only update the subtask if you're doing a transition. However, when you're updating a ticket by simply editing it, no transition, and thus no post-function, will execute.

You have a few choices:

*Automation plugins (or Jira Service Desk) that listen for updated issues.

*Scripting plugins (such as scriptrunner) that use script listeners to listen for "issue updated" and then updating sub-tasks through scripts, or use script fields which can automatically update other fields in other issues

Hi Sana, 

Thank you!!  Once I read it, it all made sense. I think I was just thinking to much about it.
