SAP BTP Side-by-Side Extensibility

— flexibility for your processes

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.

What is SAP BTP Side-by-Side Extensibility?

This approach enables the development of extensions on the SAP Business Technology Platform, without interfering with the SAP S/4HANA core code. The solutions run in the cloud, and communication with the ERP system takes place via secure API interfaces. Integration with SAP S/4HANA is handled through REST APIs, OData services, or dedicated integration services.

Extensions built in this way can be made available within the Fiori Launchpad or SAP Work Zone, providing easy access for end users.

As a result, the system landscape can be expanded in a flexible manner, in line with the Clean Core principle, which emphasizes keeping the SAP core system clean and unmodified — in accordance with the latest best practices and recommendations.
