Do we still need BW with Suite on Hana?

So, we are a small company, 500 users, with a single ECC 6.0 instance and SAP BW, Enterprise Portal 7.3.1 for several years and recently BI 4.1,

We are planning to start project for Suite on Hana.  And the question, like many, is will we still need BW?  Our ECC system is 1.3TB with data back to 2007 and BW is about 500GB.

If we were directed to report directly on ECC, what would be the trade offs?  We currently use bex web, some webi, dashboards(excelcius) and starting to work with Design Studio 1.3.  We don't have BPC and have considered BW Integrated Planning to allow for better what if scenarios in analytics.

How do others plan to answer this question? I know... it depends, but I am looking for others that can provide their experience and thoughts on how to answer this question to our executives.

Sincere Thanks!

Hi Lee,

the point is what you're using BW for.

If your primary use of BW was just as a operational report repository for your SAP applications  (ERP, CRM, SRM, APO etc.), then you're right, BW is not needed anymore, since with native HANA Live delivering real time operation reports on top of the transactional data, that's a much better design.

However, if you're really talking about your enterprise-wide data warehouse strategy, where you might have data coming from several sources and where you're going to maintain your corporate historic data for legal & financial reports for longs period of time, then yes, BW (even more, HANA BW) is the way to go.
