What configuration affects if a story can have child tasks?

[Martin Honek]

We have several next-gen projects in our Jira. I can create child issues in some of them, but not in one particular project. The button is just not there:

At first I thought I lack privileges to do so... but I am a member (and even an admin!) in that project, so this is clearly not an issue.

I tried to work around this - to create a task and "add a parent" to it. Sadly, that option offers me only epic parents. I would like to have the usual hierarchy of epic-story-task-(subtask) instead.

What other configuration did I miss? Or is the issue, possibly, elsewhere?

Hi @Martin Honek

One thing worth checking is if the sub-task issue type is activated in that project:

• Select Project Settings from the side-bar
• Select Issue Types
• Ensure sub-tasks have been added from the left-hand menu. If not, add it to activate child issues

^ This does hide the button if sub-tasks are not added. If this isn't the issue, let us know :)

I can see sub-tasks in that project's settings: https://i.imgur.com/EOeiqqV.png

Is there something else we need to do with them?

Hi @Martin Honek

Are you sure that's not a custom issue type? Sub-task for Next-Gen is "Subtask" rather than "SubTask"

If you press the "+ Add Issue Type" button - is there another Sub-task issue type to add?

Nice catch! It was a custom type left over from past. The interesting part is: when I tried to add another type (like you suggested), I couldn't: https://i.imgur.com/8wOfGUj.png

I had to remove the old one, before I could add the new one. Having a custom "SubTask" type prevented adding the built-in "Subtask" type. I am not sure if that is the intended behaviour, or an obscure bug in case sensitivity... but thanks for the solution!
