Authorized administrators can delete roles. When a role is no longer used, deleting it will keep other administrators from accidentally assigning it to a user.
When you delete a role, it is automatically removed from the accounts of users to which it has been assigned. The user account search feature allows you to locate accounts that have no roles assigned.
To delete a role
In the main menu, click Setup and then click Roles. The Roles List opens.
Locate the role and click its delete link. The system asks you to confirm the deletion.
Click OK.
