Why can't I create a subtask?

[Greg Harabedian]

I seem to be unable to create a subtask in a project where I can in other projects.  The documentation states:

To create sub-tasks, you need to have the Create Issue permission in the parent issue's project.

It seems that the default permission scheme is assigned to this project and has the "users" group  assigned to this permission.  I am in the "users" group.  I'm wondering why I can't create a sub-task?

[Kari Ringo]

I am running into the same problem and it isn't effecting everyone.  Just random users....  Has a bug or fix been identified?

[Dave Slavens]

We started seeing it too (today).

[Kari Ringo]

I confirmed all of my effected users are listed as developers.  There is nothing that differentiates them from other users who still have the ability. 

[Dave Slavens]

I just noticed that some of my user have been switched to the new UI. I'm having them switch back to the old view since the new view doesn't support the Multi-Select Drop Down List.

[Kari Ringo]

I advised those effected to do the same.

[Inga]

We had the same issue today, but it was caused by revoking access from the project lead that was a default assignee. I saw a proper error message in the old view, i think the one above is like general error for quite a few reasons. It was neither permissions, neither required fields in my case

[Kari Ringo]

This is the new sub-task button.   JIRA will all be going to this as the new view continues to roll out.  It's weird that it doesn't effect all of my users yet. Just a select few.  Most still have the option available under the ellipses.

Getting this when trying to create sub task. Not having issues on any of the other 7 project boards. Just one. And it was working until about a week ago. BA and Scum Master dead in the water on sub task creation.

Same here - exact same issue and only on some projects

Is this a bug in Jira? Any suggestions/ideas welcome. We are on JIRA Cloud.

I do have permission to create issues in the JIRA Project and I can create issues, just not sub-tasks.

Can you try this : Jira Admin access needed 

Go to Field configuration under project settings > Fields > Field configurations

Scroll down to Assigned PO and make it Optional (required should be visible on your jira screen) and then try creating subtasks.

Refer screen shot

[bfrost]

I don't have an "Assigned PO" field. Is there another way to get this to work, please? We are stuck not being able to create subtasks. Thanks much!

[Deleted user]

I to do not have an "Assigned PO" 

[Kristina Radeva]

The problem I had with this got solved by removing the Default Assignee in the project itself, because the employee was already gone and every ticket auto-assigned new issues to them, which is new issues couldn't be created. 

[Uday Joshi]

Thanks Kristina. We had the same problem. Jira should have given a proper error message to avoid all this confusion.

[Kristina Radeva]

I know! Thankfully it took me only a few hours to figure it out :)

[Leonard_Gray]

One of our Boards just randomly lost ability to add sub-tasks. No permission changes have been made and we have several other projects where this is not occurring.

Get an error ! triangle that says, "check your network connection".

Pretty bad...stuck with adding task breakdown in Description area. Help from JIRA would be great.

We were facing the same issue and we don't have the "Assigned PO" too. 

 This fix is to set the "Default Assignee" for the project to "unassigned" via project setting -> details, as the original default account seems not available any more.

Hope this helps

I do not have an Assigned PO field. I checked all our required fields, and they all make sense and have spot checked several items to make sure all the required fields are indeed filled in.

We have not had a default assignee who has left.

I also checked permissions. I can create any other issue type, just not subtasks.

The subtask type is enabled (I can see the button and click it); it just does not work.

Any other suggestions/ideas would be appreciated!

[Aleksander Kulesza-Milewski]

my resolution:

check 

permission scheme -> "Create Issues"

and:

Project settings -> People 

You need the same role for user from project as is granted in permission scheme for 'create issues'.

[Kristina Radeva]

I have both of these set up correctly and I'm still getting the error message. 

[bfrost]

Me, too! and I do not have an Assigned PO field.

[Aleksander Kulesza-Milewski]

I had the same problem but solved it. You can find answer above.

The point is to check: permission scheme (create issues) and role in the project for user.

[HarryH]

Check your permission, I think you need a developer role for this project.

[Greg Harabedian]

Yes, sub-tasks were enabled for the project and sub-tasks are added to the issue type scheme.

[Maro Hamamjyan]

I have the same problem, what was the solution?

[Tim Freestone]

Me too. Any solution would be great. Is it a problem with the new Jira version?

[Dave F]

Has anyone had any luck resolving this issue? Please share the fix for others.  Thanks

[Joe Pitt]

Sub-tasks can only be created if your JIRA administrator has enabled sub-tasks and added the sub-task issue type to the project's issue type scheme.
