Restrict sub-task creation until the Parent is in a specific status

Summary

Limit the creation of sub-tasks in a project until the parent task is in a designated status.

Environment

Jira cloud

Solution

To implement restrictions on the creation of subtasks within a project, depending upon the status of the parent issue:

1. Add a distinct workflow for the sub-task issue type within the specified project.

   

2. Configure a validator in the create issue transition workflow

   

3. The validator suitable for use in this scenario is the Parent Status Validator.

   

4. Add the validator and publish changes made to the workflow

5. This will prevent the user from creating a subtask until the parent task is not in that particular status.
