HANA Live with S/4

[Private_Member_9643]

How does HANA live is going to work with S/4? We are currently using HANA live on sidecar with ECC system on DB2 but we will be upgrading to S/4 in future so is SAP going to change the existing HANA live content with new table structure of S/4 HANA?

Thanks,
Kamaljeet

Hi Kamaljeet,

Please see a similar discussion in scn here:

In a nutshell:

1) HANA Live is proven concept and technology. It was perfectly demonstrated with Suite on HANA and in side-car scenarios with HANA as a datamart.

2) It is possible to use the HANA Live concepts and create HANA views on top of S/4HANA, however, there is no pre-defined HANA views available from SAP currently on SAP S/4HANA table structure.

3) With SAP S/4HANA, there are CDS views available which are similar in concept as virtual data models in HANA Live. However CDS views are created in ABAP layer of SAP S/4HANA.

My question is that, Is SAP going to update existing predefined HANA live views which is on ECC to point to new tables which comes with S/4? There should be some migration path for it with S/4?

Hi Kamaljeet,

There is no plan to update the existing HANA Live views from ECC to S/4HANA.

As mentioned above with S/4HANA, there is a new concept of CDS views available which are based on top of S/4HANA tables.

Hi Kamaljeet,

• SAP has introduced exciting improvements with S/4HANA Analytics (formerly HANA Live) in 2013.
• HANA Live delivers real-time, in-place operational reporting without the need for classic ETL process chains.
• To date, the HANA Live virtual data models were defined in the HANA database layer itself as HANA calculation views.
• This led to a duplication of security roles between the Business Suite for transactional processing and the HANA database for operational reporting. 
• In addition the virtual database models did not support hierarchies well.

With S/4HANA, SAP renamed HANA Live as S/4HANA Analytics. The new name comes with a number of new changes:

• Instead of HANA calculation views, S/4HANA Analytics uses Core Data Services (CDS) to define views that are still created in the HANA database but defined and accessed through the ABAP layer.
• This change allows for a unified set of security roles for transaction processing and analytics. The data model for S/4HANA has been drastically simplified. S/4HANA supports the new data model by providing a ready-to-use content using CDS view. The CDS-based content will be released together with the new S/4HANA innovations.
• Hierarchies as defined in the SAP Business Suite are also supported in S/4HANA Analytics.

So what for the Users?

• For current users of HANA Live nothing changes.
• The existing virtual data models will continue to be supported by SAP.
• Once customers migrate to S/4HANA, the new CDS-based views can be used against the simplified data model in S/4HANA.
• While the toolset for defining views changed from the HANA Studio (for HANA Live) to CDS (for S/4HANA Analytics), the skillset for defining data models is the same. 
• SAP has also announced a tool-supported migration path from HANA Live to S/4HANA Analytics.

Hi Adlin,

you wrote

SAP has also announced a tool-supported migration path from HANA Live to S/4HANA Analytics.

Is this tool already released? How's it named? Is it available for download in SAP Software Downloads?

Many thanks

That's unfortunatelly not true. There is no Migration tool and there will be None.

I just asked SAP in Walldorf.

Hi Klaus,

bad news, but many thanks for sharing it!

Do you know if there's a tool available to map HANA Live views to the new S/4HANA database structures?

Best regards

Hi there,

I found this resource. It doesnt answer your query but nevertheless an useful one on S/4.
