Automatic copy of custom fields from an Epic to "issues" in the epic

[jamila.augustine]

Hi,

What would be best approach to get an automatic update (copy) of custom fields from an epic to issues in the epic?

Currently, we have almost 10 Tasks per Epic and a lot of fields are common between these issuetypes.

Once an epic has been created, any time someone creates a Tasks and links it to an Epic, I would like to have all the custom fields from that Epic copied into the newly created Task.

Appreciate your inputs. Thanks

Post function Copy Value from other Fields with Issue Relation: Epic to Issue in Transition does the trick.  I created the post function at create transition and made Epic link "required".

You could use Automation for Jira, we currently rely on to similar things. When we create a task that is associated with an Epic it will automatically copy components and labels.

Thanks @Mikael Sandberg : Automation Plug-in would have to be purchased, right? I was hoping to find solutions which are built-in..or maybe with ScriptRunner which we have.

There is no built-in option, but yes you can do it with Scriptrunner, take a look at this thread, it has an example of how to do it, https://community.atlassian.com/t5/Jira-Core-questions/ScriptRunner-copy-Epic-custom-field-to-every-Epic-child/qaq-p/1042331

Hi @jamila.augustine - Yes it is possible through post function itself. Use Write field on linked issues or subtasks postfunction in your epic transition, and it will update the fields in child tickets.

Hi @simarpreet singh : Yes, thanks. i had in meantime also figured it out..Post function Copy Vlaue from other Fields with Issue Relation: Epic to Issue in Transition does the trick.  I created the post function at create transition and made Epic link "required".

Hi, where to find this option in Post Function? On my jira instance there is not such a thing like Write field on linked issues or subtasks

Hi, I also do not find anything as "Write field on linked issues or subtasks" in my instance. Can anyone help in locating it?
