Deciding factors for BW/4HANA, EDW on HANA and S/4HANA Embedded Analytics

[former_member193715]

I am sure most of us have been asked to choose one or combinations of the following tools to build an Enterprise Data Warehouse.

(1) BW on HANA or BW/4HANA

(2) EDW on HANA

(3) HANA Live or S/4HANA Embedded Analytics

It's an interesting topic and I have discussed this with various folks. There are number of factors that we need to consider before we finalize these tools. It varies based on customer, eco systems(source, ETL and reporting tools) in the landscape, support team...etc. I have listed some of the key factors and compared with these 3 tools.

Criteria	BW on HANA or BW/4HANA	EDW on HANA	HANA Live or S/4HANA Embedded Analytics
Significant current BW investment	Yes
Significant SAP sources	Yes
Significant non-SAP sources		Yes
Zero data latency and operational reporting from SAP systems			Yes
Business content delivery	Yes		Yes
Data cleansing & Data harmonization	Yes	Yes
Time dependent master data	More	Limited	Limited
Reuse features(e.g.:Hierarchy) from SAP business suite	Yes
Integration with big data	Limited	More
Planning capabilities	More	Less
Predictive analystics	Limited	More
Maturity of tool	More	Less	Less
Availabitly of competent resources	More	Less	Less

Here is the summary if we need to do this in 1 line.

• May go with BW on HANA / BW/4HANA and HANA live / S/4HANA Embedded Analytics if BW has been in the landscpae for a while


• May go with EDW on HANA + HANA live / S/4HANA Embedded Analytics if BW is currently not in the landscape


• May go with BW on HANA / BW/4HANA + EDW on HANA + HANA live / S/4HANA Embedded Analytics if BW has been in the landscpae and leverage features of enterprise HANA
