SAP BW/4HANA Migration & Redesign of a Global BW Landscape

From classic SAP BW to a high-performance, future-proof BW/4HANA architecture – with a reduced footprint, improved maintainability, and faster reporting.

Initial Situation

The client operated a historically grown SAP BW landscape with many redundant objects, complex loading chains, and performance bottlenecks in reporting. At the same time, new business requirements arose that were difficult to implement with the existing architecture.

Objectives

Migration to SAP BW/4HANA with a modern architecture design
Reduction of data and object redundancies
Performance optimization for loading processes and reporting
Improved maintainability and clearer responsibilities

Approach & Implementation

The first step included an analysis of the existing architecture and the most important reporting scenarios. Based on this, a target architecture following the LSA++ approach was designed, including layer definitions, naming conventions, and governance rules.

In several iterations, data models were consolidated, loading processes optimized, and BW objects migrated step by step to BW/4HANA. In parallel, SAP HANA Views were integrated and SAC was connected for self-service reporting.

Results & Added Value

Significantly faster loading and reporting times
Substantially reduced object footprint
Transparent, documented architecture with clear responsibilities
Foundation established for future analytics use cases

In this engagement, I worked as a SAP BW/4HANA Consultant, responsible for designing and implementing modern enterprise data warehouse architectures.

As a SAP BW/4HANA Expert and SAP BW/4HANA Freelancer, I covered data modeling, data flows, and performance tuning.
