Unable to create subtasks for all issue types (Epic/Story/Task)

Unable to create subtasks for all issue types (Epic/Story/Task)

I tried the Field Configurations and Screen Configurations but didn't find a place to configure it.

How can I enable or restore this feature back?

The cloud version has this function by default without configuration.

Hi @Fengjie ,

It could mean that the issue type scheme for the project does not include subtasks. You should add a sub task to the issue type scheme.

Hi @Ollie Guan 

Thanks for reply.

I checked Project settings .The subtask issue type exists in the issue type scheme associated with the project (as shown in the screenshot below)

And Sub-tasks are enabled in the Sub-Tasks administration page

Hi @Fengjie ,

看上去你并没有使用系统默认的Sub-task，而是自己创建了一个新的IssueType，可以做一些尝试：

1.Issue Type Scheme里把原来的Sub-task加入，是否可以创建？

2.Workflow里哪一类工作流关联到了你的Subtask？

3.其它Project也无法创建子任务吗？还是仅仅这一个特定的Project？

Hi @Ollie Guan 

可以直接用中文哦. 因为一些原因,云版和 server 都有用. 

最后发现是插件被人禁用了的原因,把相关插件启用就出来了. 操作方法如下:

管理>插件>插件管理>选"系统">问题操作插件>查看问题 Ops 栏创建的子任务链接 (create-subtask)
选择启用

[Ollie Guan]

这的确是个很隐秘的配置，之前我们也遇到过类似情况，移动端访问Confluence H5页面无法进行关键字搜索，后来发现也是类似的插件被禁用导致。

Florin and Ollie already got the first two things to check.  Third is:

Has your right to create issues in this project been removed?  Can you click "create" and check that you can select this project?

[Fengjie]

Thanks,Yes, I am logged in as a JIRA administrator and have all permissions.

Ok, it was worth a look, as it's one possibility here, but I see Ollie's answer turned out to be the one!

Something that might catch you out in the future though.  Administrator rights do not mean "can do anything", they only give you administrator access.  Project permissions are separate.  It is possible to have an admin who has no access to do anything in any project!  (But admin rights means they can give themselves project permissions if they want)

Hello, 

It could also mean that an global administrator has globally disable subtask

Hope this help

Hi @Florian PEREZ [Valiantys Administrator] 

Thanks for detail page for enable sub-task.

I checked  Sub-tasks are enabled in the Sub-Tasks administration page(screenshot below))
