When you edit a site category, you cannot edit the site category ID, which is provided by the system. If you change the name of the site category to a name that is already in use, an error is displayed indicating that the site category cannot be saved. You must provide a unique name before the edits that you have made can be saved.
To edit a site category, perform the following from the Business Control Center:
Log into the Business Control Center and select Site Administration.
Click the Site Categories link.
Right-click the site category, and click Edit. Begin editing the site category.
Save the changes you made to the site category by clicking Save. Click Review Changes for a preview of you changes. Click Cancel to erase your changes and keep the site category in its previous version.
