Is SAP Correct that Customers Should Use BW4HANA Instead of Other BI Tools for Integration to HANA?

Executive Summary

  • SAP has told customers that they must use BW as a BI solution for HANA.
  • How accurate is SAP on this topic?


SAP has been communicating to customers that they should buy BW4HANA for BI under the premise that SAP is not designed to integrate well with 3rd party solutions.

Our Analysis

  • Using BW means very serious productivity issues long term.
  • BW is not effective where it is implemented.
  • The idea that an RDBMS can’t connect effectively to anything but a specific BI tool is very odd. This brings up the question of what is an RDBMS. Overall, this topic needs to be analyzed. This is not to say it is not more difficult, but adapters can be written to any database.

This is pointed out in the following quote.

“HANA is widely SQL92 compliant, CDS views are an extension of SQL92. It may be an issue that third party BI vendors do not yet invest in HANA extensions and optimizations. Anyway, there is no CDS view that can only exist in S/4 or BW/4HANA. In the end it are native database artifacts that can be created via DDL statement.– Dr. Rolf Paulsen


SAP’s arguments are based upon integration and the logic that customers must use what they provide. That says nothing about what is actually effective or good.

In this book, you will review the strategies commonly used by most companies for mitigating software project risk–and learn why these plans don’t work–and then acquire practical and realistic strategies that will help you to maximize success on your software implementation.
