Managing Directory Entries
The ability to add/edit and delete an entry is provided by the relevant permissions that can be set up by your Jira Administrator. You will be able to perform only the available actions.
Note that you will not be able to delete an entry if it is linked to issues.
The entry template is set up by Jira Administrator. If you need extra parameters, just ask your admin to add them to the required directory template. The order or mandatoriness of a particular attribute can also be changed by the admin.
