Extend SAP on BTP without disrupting the core
Every SAP landscape has processes that standard S/4HANA cannot cover and business logic too specific for off-the-shelf configuration. BCS builds these extensions on SAP Business Technology Platform, keeping the S/4HANA core clean while delivering the exact process the business requires, at the speed agile development allows.

Pro-code, low-code, or AI services: BCS designs the right architecture
The choice between pro-code and low-code is not a preference, it is an architecture decision driven by complexity, data model requirements, integration depth, and who will own the application after delivery. Getting it wrong costs more to fix than it would have cost to design correctly.
BCS evaluates every extension requirement against SAP's clean-core boundaries before any build decision is made. Complex business logic with custom data models runs on CAP. Business-owned approvals and process extensions run on SAP Build. AI-driven capabilities are embedded via BTP AI Services. The architecture governs the choice, not the preference of the development team.
The failure modes that turn BTP extensions into liabilities
BTP custom development projects that fail do so predictably, and almost always for the same set of architectural and governance reasons. Clean core violated at the start, APIs selected without performance validation, no DevOps discipline, no performance testing at scale. BCS is structured to prevent each one before it occurs.
What well-built BTP extensions deliver to the business
BTP extensions close the gap between what standard SAP delivers and what the business actually needs, without touching the core. A platform that stays upgradeable, a differentiating capability owned by the business, and architecture that does not accumulate modification debt over time.
Process differentiation without technical debt
Genuine business process differentiators can be built on BTP without touching the S/4HANA core. Competitive advantage is delivered through the extension layer, not through customisations that lock the upgrade path.
Faster process execution
Manual approval chains, paper-based inspections, and Excel-driven workflows replaced with purpose-built BTP applications that execute in seconds and route automatically.
S/4HANA stays upgrade-safe
Every BCS BTP extension uses stable, versioned S/4HANA APIs and clean-core integration patterns. SAP quarterly innovations are adopted without breaking extension integrations.
Consistent user experience
BTP applications built on SAP Fiori design principles deliver the same look, feel, and interaction model as standard SAP applications, reducing training overhead and adoption friction.
Applications that scale with the business
BCS BTP applications are designed for production volumes and multi-tenant operation from the architecture phase. Scale is a design input, not a production discovery.
Business ownership of low-code applications
SAP Build applications delivered with citizen developer enablement and governance, so the business owns and evolves the process extension without raising a development ticket.
How does BCS deliver a BTP custom application?
BCS BTP development follows a five-phase approach that enforces clean-core compliance, CAP or RAP architecture quality, and DevOps discipline from the first sprint. Every extension is designed against the SAP upgrade path before it reaches production.
Discover and Scope
Requirements workshops, process mapping, and clean-core compliance assessment define what the BTP application must do and how it integrates with S/4HANA. The pro-code (CAP or RAP) versus low-code (SAP Build) decision is made on complexity, ownership, and lifecycle requirements.
Architecture and Design
The CAP or RAP data model, API surface, integration architecture, Fiori UX, and CI/CD pipeline are designed before development begins. Architecture review is a gate, not a checkpoint that can be skipped under time pressure.
Build, Sprint 1 to MVP
Iterative sprint delivery uses the BCS reusable component library and SAP Build accelerators. Business users see a working application by sprint three, not at programme end.
Test and Harden
Functional, integration, and performance testing run at production volumes. Security review against BTP security guidelines and SAP Cloud Identity Services configuration is completed before deployment.
Deploy and Enable
Production deployment runs through the CI/CD pipeline with multi-environment promotion. End-user training, citizen-developer enablement, and transition to a BCS-managed or client-operated support model complete the handover.
BTP development depth across the full platform
BCS BTP practice covers every development surface of the platform, from CAP enterprise applications and SAP Build low-code solutions to BTP AI services and API management. Each capability is delivered within the clean-core boundary, with DevOps governance and upgrade-safe API patterns built in from the first sprint.

What other SAP BTP partners cannot offer
BCS embeds three proprietary platforms into every BTP application programme. Symphony makes applications autonomous. deKorvai adds predictive intelligence to application data. Anugal embeds compliance into application workflows. These are not add-ons, they are part of the architecture from the first design sprint.
Agentic Operations Platform
Symphony
Symphony agents are embedded into BTP application workflows at go-live, autonomously handling approval routing, exception escalation, and background process execution within the application architecture.
- Agentic workflow integration inside BTP applications
- Autonomous approval routing and exception handling
- Symphony agents callable from CAP and SAP Build workflows
- Background process automation layered on BTP apps at go-live
AI Decision Intelligence
deKorvai
BTP applications built on clean S/4HANA data are the ideal surface for embedded intelligence. deKorvai connects to BTP application data layers and pushes predictive signals, recommendations, and anomaly alerts directly into the UI, so the application does not just display data, it acts on it.

What makes BCS different for SAP BTP development?
12 years of SAP delivery and 40+ enterprise programmes have shaped a BTP practice where architecture quality is enforced before the first sprint, not reviewed after the first production incident. Most BTP projects succeed in the build and fail in operations and upgrade cycles. Here is what BCS does differently.
Architecture before code
Every BCS BTP programme starts with an architecture design phase. Data model, API surface, integration patterns, and clean-core compliance rules are defined before the first sprint begins.
Clean core enforced as a delivery standard
BCS BTP extensions use only stable, versioned S/4HANA OData and REST APIs. No direct BAPI calls, no RFC dependencies, no modification namespace violations. Upgrade safety is non-negotiable.
Component library compresses delivery time
BCS maintains a reusable CAP component library, authentication patterns, S/4HANA integration adapters, Fiori layout templates, and error handling frameworks. The first sprint starts from a tested baseline.
DevOps from sprint one
CI/CD pipeline, transport management, automated testing, and multi-environment promotion are set up before the first line of application code. Quality gates do not appear at go-live.
Pro-code and low-code in one programme
BCS designs hybrid architectures where complex logic runs in CAP and business-owned processes run in SAP Build, giving the business ownership of what it should own without sacrificing architecture integrity.
Post-delivery ownership transfer
BCS BTP deliveries include citizen developer enablement for low-code applications and developer documentation for pro-code applications, so the client owns the asset after go-live.
