Extend S/4HANA without unnecessary core modifications.
We design and build the extension layer around S/4HANA — integrations, custom applications and APIs on SAP BTP — using clean-core patterns that keep the core upgradable and the extensions maintainable.
Integration Suite and API/event-driven integration
We build and operate integration flows on SAP Integration Suite for both synchronous API integration and asynchronous, event-driven scenarios. The goal is a maintainable integration landscape, not a growing pile of point-to-point interfaces.
- iFlow design and development for API-based and message-based integration
- Event-driven integration using SAP Event Mesh where decoupling and reactive processing matter
- API management: exposure, versioning and monitoring of integration content
- Migration of legacy PI/PO interfaces to Integration Suite where in scope
Cloud Foundry and Kyma runtimes
SAP BTP offers two application runtimes with different strengths. Cloud Foundry suits managed, buildpack-based application deployment with less operational overhead. Kyma, built on Kubernetes, suits containerised workloads that need more control over runtime configuration. We pick the runtime based on the workload, not by default.
CAP and RAP for custom development
For custom development, we use the SAP Cloud Application Programming Model (CAP) for BTP-native services and the ABAP RESTful Application Programming Model (RAP) for extensions built inside the S/4HANA ABAP stack — choosing the model based on where the logic and data actually belong.
- CAP services for side-by-side extensions, new business applications and cross-system logic
- RAP-based custom business objects and APIs for in-app extensions on S/4HANA
- CDS view modelling as the shared data foundation across both models
- OData V2/V4 API design exposed consistently to Fiori, external systems and integration flows
Fiori and UI5 application development
We develop Fiori elements and freestyle UI5 applications on top of CDS views and OData services — covering both new custom applications and extensions to standard Fiori apps through SAPUI5 flexibility and key user extensibility.
Clean-core extension patterns
Every extension is placed deliberately as side-by-side (on BTP, outside the S/4HANA system) or in-app (inside S/4HANA, using released extension points and the RAP developer extensibility model). This decision is driven by upgrade stability, not convenience: side-by-side extensions keep the S/4HANA core untouched, while in-app extensions are scoped to supported extension points so they survive upgrades.
- Extension placement decisions documented against upgrade and lifecycle impact
- Use of released APIs and extension points instead of core modification
- Identity and authorization design (SAP Identity Authentication/Provisioning, role and scope modelling) scoped per engagement
