Hello Rajendran,
You can set up a template as a default template. A subscription administrator will need to make sure that the Rich Text Template sharing option is enabled globally. This is located under the Labs tab. Each user will also need to ensure that they have this enabled as well. For your reference I have included the following section from the help page that explains how to set a template as a default.
New Editable Detail Pages | CA Agile Central Help
Templates help you save time when you need to create multiple sets of similar content. For example, Acceptance Criteria wording can be added as a template on a user story's description field, so that you can quickly enter the criteria in your team's standard format.
Templates are available from rich-text fields on user stories, tasks, defects, portfolio items, and discussions.
To set a template as default:
- Click the Templates button.
- Select the checkbox, located to the right of the template name, to set a template as default.
If you select the Set as Default checkbox, the template you have selected will automatically populate in a rich-text field for that work item type and field. For example, if you created the template in the discussions rich-text field on a user story editable detail page, the template will automatically populate when you create a discussion post on another story’s editable detail page. The template you created will be available in the list for other rich-text fields, such as the Discussion field on a task, but it will not be the default for that work item type and field.
Please let us know if you have any questions.
Thank you,
Christian
