Deleting a role in Resource Management
Take care when deleting roles. You cannot delete a role that has users assigned to it. If you need to delete a role and are not sure if users are assigned, you can use the View People Resources option to find out.
If no users are assigned to a role, select the Delete option. At the dialog box, select Edit and then select Delete. You should see a "Delete successful" message in the bottom-left corner of the dialog box.
