Automation rule to populate tasks and sub-tasks of epic children when Epic changes

[Ann Rumenapp]

Looking for some automation rule help - I have a rule for when an Epic change 2 custom fields (Project & Work Type) then populate that value on all the Epic children.  My rule won't populate the sub-tasks though.  Suggestions on how to make the rule work for all Epic child cards & Sub-tasks?

Here is the rule that partially works:

Hi @Ann Rumenapp ,

As it seems your branch searches only for stories, try using JQL branch and using JQL "parentEpic = {{issue}}". The parentEpic function looks for all the tasks in the epic and their subtasks.

THANK YOU so much!  That worked.  I'm just learning/testing out how to write automation rules.

Do you have a link to Atlassian documentation on branch search function options?  I have another rule to update a card and it's sub-tasks that there is probably a function for

Good luck! Automation is fun. 

The whole documentation for JQL is here https://support.atlassian.com/jira-service-management-cloud/docs/use-advanced-search-with-jira-query-language-jql/ . If you want to see the exact options, check out functions and fields section.

I'm not enjoying this assignment for automation rules at all!  I get one rule to work and then other rules conflict.

Hi @Adam Rypel _MoroSystems_,

Today when running the automation rule, the audit log gives me this error on subtask cards: No fields or field values to edit for issues (could be due to some field values not existing in a given project)

I've checked the screen and field configurations which have the work type and project fields.  Where else should I look to figure out this error?
