SAP BW/4HANA: Next-Generation Data Warehousing Built on SAP HANA

As SAP BW 7.5 approaches the end of mainstream maintenance in 2027, organizations are migrating to SAP BW/4HANA, a next-generation data warehouse solution built on SAP HANA that offers enhanced performance, reduced complexity and cloud deployment options. SAP BW/4HANA serves as the primary migration target for SAP BW 7.5 users, providing a streamlined, HANA-native architecture that supports both SAP and non-SAP data integration. SAPinsider analysis of BW modernization shows that organizations migrating to SAP BW/4HANA gain significant performance improvements through the revamped Layered Scalable Architecture (LSA++), while extending mainstream support until 2030 for those who need additional time to plan cloud transitions.

What Is SAP BW/4HANA?

SAP BW/4HANA is SAP’s next-generation packaged data warehouse solution built natively on SAP HANA, designed to replace the traditional SAP Business Warehouse platform with a simplified, HANA-optimized architecture. SAP provides migration tools including the BW/4HANA Transfer Cockpit and Conversion Cockpit to support in-place upgrades, remote conversions and shell conversions from existing BW 7.5 systems.

What Use Cases Are Referenced?

In-Place Migration Upgrades Existing BW to BW/4HANA

The in-place migration strategy upgrades an existing SAP BW 7.5 system directly to SAP BW/4HANA on the same server, maintaining the same system ID while redesigning data models and cleaning up obsolete objects.

Remote Conversion Enables Zero-Downtime Migration

The remote conversion approach creates a new SAP BW/4HANA system in a separate landscape, allowing organizations to migrate data and content with almost zero production downtime before phasing out the legacy BW system.

HANA-Native Architecture Delivers In-Memory Performance

SAP BW/4HANA leverages HANA’s in-memory database to deliver superior query performance and simplified data modeling compared to traditional BW, while supporting large-scale analytics including IoT and Big Data workloads.

LSA++ Framework Simplifies Data Warehouse Architecture

The revamped Layered Scalable Architecture (LSA++) in BW/4HANA reduces unnecessary data redundancy and accelerates query response times by optimizing data flows within the warehouse layers.

Cloud Deployment Supports Hybrid Data Warehousing Strategies

SAP BW/4HANA cloud deployment enables organizations to run their data warehouse on cloud infrastructure, supporting hybrid architectures that combine on-premise SAP systems with cloud-based analytics.
