Content Federation is a feature that allows SAP Build Work Zone to integrate content from remote content providers, such as SAP S/4HANA and SAP Business Suite. A remote content provider is a solution that exposes content that can be integrated in SAP Build Work Zone, such as apps, groups, catalogs, and roles. The integration of the exposed content is done at the role level. All content items related to these roles are also integrated and are visible in the runtime. For example, if an administrator of an SAP S/4HANA system exposes a business role with its assigned catalogs, groups, and applications, then SAP Build Work Zone can import this role and its related content and display it in a site. The end users who have access to this site can then launch the federated apps and groups from the site. References:
