Setting a Default Template
You can set a Default Template that will be automatically added whenever a work item or request of the indicated type is created. Default Templates are defined per project and work type / request type, allowing you to set different default templates for each type within each project.
Templates can also be added to issues from the via automation or the REST API.
A Default Template is not applied when the work/ request type is changed later in “work item update” operation.
You must have project administrator permission to set default templates.
To set a default template:
Navigate to the templates page either by selecting Checklist from the More menu on the project nav bar or by selecting Manage templates from the … menu for the Checklist.
Click Set default for the appropriate template.
Select the work types and/or request types you want the template to be applied to.
Note that a cloned checklist takes precedence over a default checklist. If a work item with a checklist is cloned, the default template will not applied.
Every Jira workflow contains an Issue Created post-function by default. This is required for default templates to work and should not be removed.
