Sites TabYou use the Sites tab to add sites within an organization and to specify associated information. Sites are defined at the organization level. You can add as many sites to the same organization as needed.
Site names must be unique across the system. You cannot use the same name for different sites in different organizations.
After you add a new site, you cannot delete it, but you can make it inactive. If a site is inactive, users cannot access site-level records for that site.
For information on adding sites, see Add a Site.
