I am using the Jira automation to sum the logged hours (worklog).
Trigger is an issue worklog update. Now once the worklog is updated (worklog update trigger) for an issue, I want to sum up the worklog of all the issues under the parent epic and add it to a custom field in epic.
Or maybe from an epic only I will use the trigger and I want to sum up all the worklog from the child issues (stories/bugs/tasks)
Or how can I capture worklog "changed from" for defining smart value
Is it possible?
