I need a quick filter for a user that has subtasks assigned & stories they have subtasks

[Natasha Cronen]

I need a quick filter for a user that has subtasks assigned to them AND stories they have subtasks assigned to them but are not the assignee of the parent story.

Background: I believe I have the correct JQL, and we have recently installed the ScriptRunner add-on, but I am still unable to use 'IssueFunction' 

Here is a sample of the JQL I want to use, that I think will get me what I need:
assignee = ncronen OR issuefunction in parentsOf("assignee = ncronen")

I am getting the error: "Field 'issuefunction' does not exist or you do not have permission to view it."

How do I resolve? Is this the correct JQL to provide the results I'm looking for?

As per this post

https://community.atlassian.com/t5/Jira-Software-questions/Do-we-have-any-substitute-for-issuefunction-in-JIRA-Cloud/qaq-p/1539971

...you can use "issuefunction" only in the Enhanced Search Page. The post includes a workaround.

Hi @Natasha Cronen ,

Standard JQL doesn't easily allow it but the results can be quickly found using our professional indexing service. If you are still looking for a solution you can check out:

• JQL Search Extensions

After you install the app you can simply search:

assignee = ncronen OR issue in parentsOfSubtasksInQuery("assignee = ncronen")

You may want to check out the docs as well.

I hope this helps!
