I have created new work type called feature.

[Thanuja Gunasekara]

I have created a new work type called “Feature.” I would like to add child work items to the existing tasks in my backlog. Additionally, I need to maintain the following work‑type hierarchy:

1. Epic

2. Feature

3. Task

4. Sub task

5. Bug

Hi @Thanuja Gunasekara , you can only add subtasks as a child to a work item that is equivalent to a task level. 

jira standard provides: Epic > Story/Task/Feature (if created) > subtask

jira premium provides: Program > Initiative > Epic > Story/Task > subtask

HI @Thanuja Gunasekara 

Welcome to the community.

Then you should rename the Epic to Feature and rename Feature to Epic and then adjust the hierarchy.

This will mean that you can't add child feature to an Epic as this is no called Feature.

Thank you for your response.

I need to maintain hierarchy levels in the project as follows:

• Epic – Features are child tasks under Epics
• Feature – Tasks are child tasks under Features
• Task – Sub-tasks are child tasks under Tasks
• Bug – Bugs can be created under Features, Tasks, or Sub-tasks

Hi @Thanuja Gunasekara 

This can be done, see my previous comment.

Rename the Epic issue to Feature, then you can use the options from Epic on the Feature level.

Create a new issue type or re-name the Feature Issue type to Epic and adjust the work item hierarchy, add a level above Feature and add the Epic issue type to this level.

Thank you for your response.

 I can only create sub tasks under features; I’m not able to create child tasks. Please refer the screenshot.

Also, the feature task doesn’t have a parent field to set the parent task details.

Hi @Thanuja Gunasekara 

1. Delete the current type Feature.
2. Rename the Epic type to Feature.
3. Create a new Type called Epic
4. Adjust the hierarchy (https://support.atlassian.com/jira-cloud-administration/docs/configure-the-issue-type-hierarchy/) to place the new Epic type above Feature
