Validation occurs whenever a site is added into a sharing group using Site Administration. This validation reviews the sharing group and ensures that the site does not belong to another sharing group that shares the same ShareableTypes. This validation will not check multi-component ShareableTypes, or ShareableTypes that contain more than one component, for example a Shopping Cart and a Product List.
Data sharing validation methods can be configured in the SiteGroupManager component. However, these rules will be available only in the Site Administration application. Refer to the ATG Platform Programming Guide for additional information on the SiteGroupManager component.
