Hi Swathi,

Option 1) Hana as Secondary Data base-  SAP ECC is still on say DB6 (HANA is OLAP and ECC is OLTP )

 

Load Information using either SLT or BODS into Hana Data Base  and Build Models using replicated data and consume models in BI Client Tools

 

Yes, this is a standard way of using ECC data for Data warehouse reporting in using HANA DB. Another option is also to use HANA RDS. You can also refer to the Solutions section here to get more insight on different possibilities on HANA with ECC.

 

Option 2)Is there a way to migrate your SAP ECC DB6 (or any ECC Database) to HANA Database  and use SAP ECC as both your OLAP and OLTP Systems  

 

In this case you don't need SLT or BODS

 

Is the second option available for customers ? If yes, why clients go for first where you have maintain data at 2 places and addition replication process

    

 

 

On the second option please check the following documents / link. FAQ, Roadmap and release Info.

 

3)Say we already have BW system in Place  what happens in that case

 

1)SAP ECC(DATA)--->BW(Cubes)--> HANA(Migrate your existing cubes to Views(Analytic or calculation Views)   if this right-  when we want to create  a new View -Do we have to create Cube in BW and Migrate to View in Hana Studio)

 

In this case it depends on how you wish to use your BW system. You can continue to use the existing BW application by migrating the underlying database to HANA (BW on HANA) or can choose to publish the BW on HANA In-memory InfoCubes and DSOs to HANA information models (Analytic views and Calc views) and can use them for reporting.

 

You can create additional InfoCubes / DSOs in BW on HANA and publish them to HANA information models. So depending on the use case, there are multiple architecture options available.

 

I would be providing the link to this thread on another forum as you asked the same question on BW powered by SAP HANA forum, http://scn.sap.com/thread/3330553

 

Regards,

 

Ravi
