We use Jira premium, company-managed projects with a jira hierarchy as follows:
Level 4 = OKR (custom issue type)
Level 3 = Change Initiative (Custom issue type)
Level 2 = Epic or Change Event (custom issue type)
Level 1 = Feature or CCR (both are custom issue types)
Level 0 = All other standard issue types
All Sub-task Issue types
I need to write an automation rule to populate a field on issue create for issues that are children of the Change Event issue type and excludes children of the Epic issue type. What automation rule trigger would you recommend for this?
