Is Subtask and Child Issue same?

[Vineela AK]

Is Subtask and Child issue same in Jira? I am trying to create a subtask and i don't see a subtask. Can we create a sub task for To Do, In Progress?

Hi @Vineela AK ,

welcome to the Atlassian community!

Please verify that sub-task issue type has been defined in your project Issue Type scheme. Moreover subtask creation is status indipendent so it could be created in each status.

Hi Vineela - Welcome to the Atlassian Community!

It depends somewhat on the context, but yes a sub-task is considered to be the child of it's parent issue. 

Now having said that, you might need to enable the ability to create Sub-tasks. Follow the guidance here to be sure it is enabled.

Heya @Vineela AK

In terms of the differences between the subtask and the child issue, there perhaps is a miss-conception here. So the issue type "Sub-Task" is seen to be the lowest issue in the issue hierarchy, so in terms of creating another child sub-task this is not possible! In jira, we use the following hierarchy to work on issues (generically for most projects):

Epic -> Story -> Task -> Sub-Task

I'd advise that you create a task and link the relevant sub-task (child tickets) to the task ticket! 

Kind Regards,

I'm afraid that's wrong.  You can't do that in Jira. 

The Jira hierarchy is Issue -> Sub-task.

If you have Jira Software, then you get  Epic -> Issue -> Sub-task.

To get a bigger hierarchy, you need to add an app to do it - Atlassian's own Advanced Roadmaps, Tempo's Structure, my own Adaptavist's Hierarchy, JXL, Links Hierarchy and so on.  A lot of these work off issue links - Jira doesn't itself understand the hierarchy that the apps show, but it does understand the linking.
