Extend SAP Without Limits —SAP BTP Extensions
Build powerful SAP extensions using CAP, RAP, SAPUI5, and SAP Build on SAP BTP — without touching your SAP core. Side-by-side and in-app extensions that are upgrade-safe, cloud-native, and built to last. Delivered by SAVIC, SAP Platinum Partner.
Extend Any SAP Process — Without Modifying the Core
SAP BTP Extensions are custom applications, workflows, and enhancements built on SAP Business Technology Platform that extend SAP S/4HANA and other SAP solutions without modifying the SAP core. Using technologies like CAP, RAP, SAPUI5, and SAP Build — connected to SAP backends via standard OData and REST APIs — BTP extensions deliver powerful customisation that survives every upgrade, every patch, and every cloud migration. SAVIC Technologies, an SAP Platinum Partner with 407+ BTP projects, designs and builds production-grade extensions that align to SAP's clean core vision.
Four Approaches to SAP BTP Extensions
The right extension approach depends on your use case, team skills, and clean core requirements. SAVIC helps you choose and implement the right pattern.
Side-by-Side Extensions
RecommendedBuild entirely new applications and processes on SAP BTP that connect to SAP S/4HANA via standard APIs — without touching the SAP core. The most future-proof extension approach.
- Built on SAP BTP using CAP (Node.js / Java)
- Connects to S/4HANA via OData & REST APIs
- Zero impact on SAP upgrades or patches
- Independently deployable and scalable
ABAP Cloud (RAP) Extensions
ABAP-NativeExtend SAP S/4HANA using the ABAP RESTful Application Programming Model (RAP) within the ABAP Cloud environment — clean, API-first ABAP development that stays upgrade-safe.
- ABAP RESTful Application Programming Model (RAP)
- OData V4 services published automatically
- Runs inside ABAP environment on BTP
- Full ABAP language with clean core guardrails
Key User Extensibility
No-CodeConfigure SAP standard applications without coding — add custom fields, logic, and business rules directly in the system using SAP's built-in extensibility framework.
- Custom fields & custom logic (no ABAP needed)
- Business rules & workflow configuration
- UI adaptation via SAP UI Adaptation Editor
- Fully supported by SAP — upgrade-safe
In-App Classic Extensions
Legacy-SafeFor scenarios requiring direct S/4HANA customisation — BAdIs, enhancement spots, and user exits implemented using controlled, documented patterns aligned to clean core principles.
- SAP BAdI & enhancement framework
- Controlled, documented customisations
- Clean core assessment before development
- Migration path to side-by-side on BTP
Why Clean Core Matters for SAP BTP Extensions
SAP's Clean Core principle means keeping the SAP S/4HANA system free of direct modifications — all customisations live on SAP BTP as extensions, connected via standard APIs. This approach ensures your SAP landscape is always upgrade-ready, cloud-migration-safe, and easier to maintain.
SAVIC starts every extension engagement with a Clean Core Assessment — reviewing existing Z-code, modifications, and customisations to define the right path to BTP-based extensions.
Request a Clean Core AssessmentNo Core Modifications
All BTP extensions are built outside the SAP core — ensuring every SAP upgrade, patch, and release goes through without breaking your customisations.
Upgrade-Safe by Design
Side-by-side and ABAP Cloud extensions are enforced upgrade-safe by SAP's ATC checks and ABAP Cloud whitelist — custom code that lasts.
Cloud-Native Architecture
Extensions run on SAP BTP's cloud infrastructure — independently scalable, containerised, and deployable without dependency on SAP backend releases.
Standard API Consumption
All extensions consume SAP standard OData and REST APIs — using only released, stable interfaces that SAP commits to maintaining across versions.

Frequently Asked Questions
Common questions about SAP BTP Extensions and how SAVIC builds them.
What are SAP BTP Extensions?
SAP BTP Extensions are custom applications, processes, or enhancements built on SAP Business Technology Platform (BTP) that extend SAP S/4HANA and other SAP solutions without modifying the SAP core. They use standard APIs to connect to SAP backends and are built using technologies like CAP, RAP, SAPUI5, and SAP Build.
What is the Clean Core concept in SAP BTP Extensions?
Clean Core is SAP's guiding principle that SAP S/4HANA should not be modified directly — all customisations should be built outside the core using BTP extensions. This ensures that SAP upgrades, patches, and cloud migrations are not impacted by custom code, making the system easier to maintain and evolve.
What is the difference between Side-by-Side and In-App extensions?
Side-by-side extensions are built entirely on SAP BTP (using CAP or SAPUI5) and connect to SAP via standard APIs — they run independently of the SAP backend. In-app extensions (like ABAP RAP or Key User Extensibility) run inside the SAP system itself but follow clean core rules to remain upgrade-safe.
What technologies does SAVIC use to build BTP Extensions?
SAVIC builds SAP BTP Extensions using the full BTP development stack — SAP CAP (Node.js/Java) for side-by-side apps, ABAP RAP for ABAP Cloud extensions, SAPUI5/Fiori Elements for UIs, SAP Build for low-code scenarios, SAP Integration Suite for connectivity, and SAP AI Core for intelligent extensions.
Can SAVIC migrate existing SAP custom code (Z-code) to BTP Extensions?
Yes. SAVIC performs clean core assessments to classify existing Z-code and custom modifications, then develops a migration plan to move relevant customisations to BTP side-by-side extensions or ABAP Cloud — reducing technical debt and making your S/4HANA landscape upgrade-ready.
