What is the relation between Epic and subtasks ?

[Pierre Allard]

Hello all,

I'd like to sum up in an Epic the time logged in tasks in this Epic, but it seems it's not possible, is that right ?

However it seems that time logged in subtasks can be summed in Epic:

But I'm not able to find how to add a subtask to an EPIC, even though I know it is possible:

Any idea please ?

Thanks in advance for your help !

Hi Pierre,

It seems this is a bug for Epics. You can vote for and follow the request here:

Ok I just found out an answer here : https://community.atlassian.com/t5/Jira-Software-questions/How-To-Display-Subtasks-on-Epic/qaq-p/1500467

So TS-964 was a task converted into an EPIC, that's why subtask section is still displayed.

But I still don't understand what this "Include subtasks" option is for...

Here is what I see in a new EPIC.

And in this Epic I've a task with this time tracking section:

Seems normal since I've also created a subtask in which I logged 5days.

But the question is why Epic time tracking section remains empty even though "Include subtasks" option is selected ?

Is this option a bug or a leftover of the time when subtasks could be linked to epics ?

And also why don't we have the "Include tasks" option available in Epic time loggin section ?  It would be so useful to me !

Thanks in advance for your help ! :)

This is all probably a bug from when you moved the task to an Epic. Sub-tasks don't directly roll up under Epics, so I wouldn't expect Epics to include time directly from Sub-tasks. 

However, are the Sub-tasks not linked to a Task? Is that option selected to roll the time for the Sub-tasks up to the Task? And is that working? Or are the Sub-tasks just orphans now?
