On August 31st , a new BW Avatar is born:
This is not BW on HANA….rather, this is BW especially and exclusively 4 HANA.
A great deal of ink has already been spilled enumerating its might and bright..but I still feel that there are lot of questions people are asking which warrants for a perusal over multiple sets of documents to kind of have an overall picture and although there are umpteen resources available in terms of great documents such as SCN FAQs, SAP Guides etc, a one-stop-shop kind of a document might help provide a consolidated reference point.
All I have tried to do, in my humble effort here, is to go through the myriad sites and documents (BIG DATA..for me) related to BW/4HANA, and have given a consolidated picture…similar to what a Datawarehousing tool, such as BW/4HANA, intends to do..
So, here we go…
|Discussion Points||Insights | Comments|

Datawarehouse Workbench will be used for the following activities
Note: Web-based administration & monitoring is already work-in-progress and will soon be delivered in next few quarters.
|What happens to BW on HANA versions (7.x on HANA)||
SAP BW 7.5 powered by and edition for SAP HANA will still be supported release options and will move into maintenance, receiving little development or new functionality moving forward.

To move to BW/4HANA, first BW has to be upgraded to
BW 7.5, edition for SAP HANA (7.50 SP04 or higher) –
Then you need to use the “Transfer tool” to convert all your old object types to new objects types (aDSO, Composite Provider etc.)
Then you move to BW/4HANA using SUM –

|What’s the Licensing framework for BW/4HANA||
Licensing will be driven by the factor that how is BW/4HANA deployed.
We have 2 options:
1. Cloud-based: Licensing will be based on subscription and Instance type selected (AWS/CAL)
2. On-premise: Licensing will remain as the existing stnd process for SAP Applications.

|Does it have Early Adopter Pgm to help transition to this brand new product?||
SAP provides an Early Adopter Pgm. Salient features of this pgm:
How to register:
How is Big Data &
IoT is supported in BW/4HANA via Smart Data Streaming (part of EIM)
Big data is supported in BW/4HANA via Smart Data Integration (part of EIM)
|Certification for BW/4HANA||Not yet available|
|How does it fit together with S4HANA||
Firstly, SAP BW/4HANA is completely independent of and not a prerequisite for SAP S/4HANA and vice versa.
S4HANA – Primary use case is operational reporting on current data from single SAP system.
BW/4HANA – Primary use case is Datawarehousing which provides consolidation (SAP + non-SAP + Big Data) and historical analysis
|What about Stnd extractors from S/4HANA flowing into BW/4HANA||
The following will apply :
It would be a good idea to follow the BW/4HANA SCN Space for all the future updates and Information:
Happy Learning !
