Can we restrict creation of sub-task based on their parent issue

[Deleted user]

I want to restrict creation of sub-tasks once their parent tasks are closed. How can we achieve this?

^ The above will work - it removes the ability to add sub-tasks, along with a suite of other edit functions. To add this to your workflow:

1. Locate the workflow for the issue type in question (Jira Administration > Issues > Workflows)
2. Click to edit the workflow
3. Press on the Status (not the transition) and press Properties
4. In the Property Key, place "jira.issue.editable"
5. In Property Value, place "false"
6. Press Add, then publish the new workflow

If this is too restrictive for you as it prevents editing also - you'll need to consider doing this via scripting using an add-on. This answer details how to restrict sub-task creation using ScriptRunner.

You can try adding jira.issue.editable = false property to your closed step in the workflow.
