Enabling and Configuring Sub-tasks
| 
PDF |
Sub-task issues are generally used to split up a parent issue into a number of tasks which can be assigned and tracked separately.
Sub-tasks have all the same fields as standard issues, although note that their 'issue type' must be one of the
sub-task issue types (see below) rather than one of the standard issue types.
Once you have enabled sub-tasks and defined at least one sub-task issue type, users will be able to:
Note
Sub-tasks are only supported in the Professional and Enterprise editions of JIRA.
Enabling sub-tasks
Sub-tasks are disabled by default. To enable sub-tasks:
- Log in as a user with the 'JIRA Administrators' global permission.
-
Bring up the administration page by clicking either the 'Administration' link on the top bar or the title of the
Administration box on the dashboard:


- Locate the 'Global Settings' sub-menu on the left hand side of the screen, and choose Sub-Tasks from the list.
- The 'Sub-Tasks' administration screen will be displayed. Click the 'Enable' link.
- The page will reload and inform you that the sub-tasks are now enabled. A default sub-task issue type has also been automatically created. You can edit it by selecting the Edit link in the Operations column.
Defining sub-task issue types
Sub-tasks must be assigned one of the sub-task issue types, which are different to standard issue types. Please note that you must define at least one
sub-task issue type before users can create sub-tasks.
Sub-task issue types can be customised on the 'Sub-Tasks' administration screen (which is described above).
The 'Sub-Tasks' administration screen allows you to create, delete, edit, translate and choose icons for your sub-task issue types. For
details, please see 'Defining Issue Types'.
Configuring sub-tasks and workflow
It is possible to restrict the progression of an issue through workflow depending on the state of the issue's
sub-tasks. For example, you might need to restrict an issue from being resolved until all of its
sub-tasks are resolved. To achieve this, you would create a custom workflow and use
the Sub-Task Blocking Condition on the workflow transitions that are to be restricted by the sub-tasks' state.

Disabling sub-tasks
Sub-tasks are disabled from the sub-task administration screen. To disable sub-tasks please follow the following steps:
- Log in as a user with the 'JIRA Administrators' global permission.
-
Bring up the administration page by clicking either the 'Administration' link on the top bar or the title of the
Administration box on the dashboard:


- Open the Global Settings sub-menu on the left hand side if it is not open already, and choose Sub-Tasks from the list.
- After the Sub-Tasks administration screen loads please click the "Disable" link. The page should reload and inform you that the sub-tasks are now disabled.
Note
Sub-tasks cannot be disabled if one or more sub-tasks exist in the system. You will need to remove the existing sub-tasks
(or
convert them to standard issues) before disabling this feature.
