Single Sign-On Between SAP BTP and SAP SuccessFactors

The concept name was not provided, but based on the sources, the most prominent concept is Principal Propagation. Principal Propagation is the mechanism for exchanging user ID information between systems or environments in SAP BTP. Developers use it to forward the identity of an authenticated user from one system to another — for example, from an SAP BTP application to an on-premise system — so that access controls and audit trails remain tied to the original user rather than a technical service account. It can also be applied across SAP BTP environments, such as propagating a principal from the Neo environment to the Multi-Cloud Foundation.
