SAP Business Technology Platform (BTP) enables the extension of SAP systems with new functionalities without interfering with the system’s source code. One of the key extension models is Side-by-Side Extensibility — an approach that allows the creation of independent cloud applications that integrate with SAP S/4HANA (on-premise, Public Cloud, and Private Cloud) via APIs.
This is a solution for companies that want to accelerate innovation without the risk of destabilizing the core system or losing vendor support.
