SAP is the backbone. But it was not built to be flexible.
SAP runs the core business processes of most large enterprises — procurement, finance, HR, manufacturing, sales. But SAP was designed as a self-contained system. Connecting it to mobile applications, web portals, partner APIs and real-time dashboards requires specialized knowledge of RFC, BAPI, IDoc, OData and increasingly, SAP BTP. Most integration vendors treat SAP as a black box and build fragile point-to-point connections that break with every upgrade.
Deka engineers understand SAP from the inside. We build integrations that are robust, maintainable and aligned with the SAP integration architecture — so they survive upgrades, support bidirectional data flow and perform at enterprise scale.
Assess & Design
We analyze your SAP landscape, identify integration points and design the optimal connectivity pattern — OData for standard, RFC/BAPI for custom, BTP for cloud-native, IDoc for batch.
Build & Connect
We implement the integration layer with proper error handling, retry logic, data mapping and transformation. Bidirectional sync with conflict resolution for offline and mobile scenarios.
Test & Harden
End-to-end testing across SAP transport landscapes (DEV → QAS → PRD). Performance testing under load, failover testing and monitoring setup for production operation.
What we deliver
Direct function-call integration with SAP using Remote Function Calls and Business Application Programming Interfaces. The most reliable method for custom business logic and transactional operations.
Standard OData services from SAP Gateway for CRUD operations and queries. We also build custom OData services when standard ones do not cover the use case.
Cloud-native integration using SAP Business Technology Platform — Integration Suite, Event Mesh and API Management. The future-proof approach for S/4HANA and cloud-first architectures.
Integration layer preparation for ECC to S/4HANA migration. We ensure all external integrations continue to work after the migration and leverage new S/4HANA APIs where beneficial.
Offline-capable mobile applications with bidirectional SAP synchronization. Incremental sync, conflict resolution and guaranteed delivery for field-sales and service scenarios.

Anadolu Efes
Anadolu Efes needed a mobile field-sales platform integrated bidirectionally with SAP across 5 countries — supporting offline operation, real-time pricing and 70+ data domains.
We built a multi-layer integration architecture: RFC/BAPI for transactional operations, OData for master data queries, custom sync engine for offline/online reconciliation. The API layer handles 200K+ daily SAP transactions.
Field teams operate fully offline with SAP data. Orders, visits and conditions sync reliably. 5 countries on a single platform with country-specific SAP configurations.
Where we apply it
- Give field sales real-time SAP pricing on their mobile devices
- Let distributors order online with live SAP stock and pricing
- Empower employees with self-service HR connected to SAP
- Automate partner EDI exchange without manual file handling
- Visualize SAP BW/HANA data in real-time dashboards
