I accidentally discovered that a jql query : parent=PID-34 is valid. This means there exists a field “parent” in JIRA. I am not aware of any JIRA screens that explicitly show this field. Is it a native field? How is it used? How is it meant to be used? Can I use it for the purposes of my plugin as well?
It’s worth mentioning that there also exists a similar parentEpic field, which can be used to get all issues in an epic, transitively taking subtasks into account.
