SAP BW/4HANA Modernization

Modernize Your SAP Data Warehouse for the Future

SAP BW/4HANA is the next-generation data warehouse optimized for SAP HANA, offering superior performance, simplified data models, and reduced TCO. We help you transition from legacy BW to BW/4HANA or build new BW/4HANA implementations from scratch.

Frequently Asked Questions

Q: Should we migrate to BW/4HANA or Datasphere?
A: Depends on your strategy. BW/4HANA if you have complex BW investments and prefer on-premise/hybrid. Datasphere if you’re cloud-first with simpler requirements. We provide assessment to help decide.

Q: Can we migrate without downtime?
A: Not for production system. However, we minimize downtime through thorough preparation, parallel development, and efficient cutover planning (typical downtime: 24-48 hours).

Q: Will our existing BEx queries work after migration?
A: Most BEx queries work with minimal changes. Some obsolete features may require redesign. We identify and address these during assessment.

Q: How much performance improvement can we expect?
A: Varies by use case. Typical improvements: 50-90% faster queries, 60-85% faster loads. We provide estimates after performance analysis.

Q: What about custom ABAP code?
A: We analyze custom code for BW/4HANA compatibility, remediate issues, and optimize for HANA (e.g., convert to AMDP where beneficial).
