How can I retrieve both parent issues and their subtasks in Jira using JQL?

[testcase1062]

I want to fetch the parent issues along with subtasks without using any plugins.

Hi @testcase1062 

If I understand what you're asking for, I don't think you can accomplish that without ScriptRunner or another plugin that extends JQL.

You might be able to work something out using the Parent function, which will find sub-tasks of a specific issue, but I think that's more limited than what you want.

Hi @testcase1062

By using basic filter option choose parent custom field and later parent = 'choose your parent issues by using multiple choice'.
In result, it will provide all the child issues of chosen parent issues.
