scenario

Australia-based systems integrator and SAP partner, Innogence set up

an SAP HANA instance at its premises, running under SAP NetWeaver

BW to run various test scenarios using large volumes of test data loaded

into SAP HANA and BW

Performance

and benefits

Customer

Feedback

The validation of BW on SAP HANA is particularly promising, as this

solution will drive a lot of SAP HANA adoption within SAP‟s installed

base. What is more is that partners developing on the SAP HANA

platform will enable new business scenarios and reach customers and

industries that SAP may have otherwise never been able to access

Query runtime roughly consists of four parts:.

1. DB Database reading time: depends on amounts of records to be

2. OLAP calculation time and large data transfer,

Non-cumulative KF, exception aggregation etc.

3. BEX Presentation, depends mainly on the size of the result set.

4. Network Network load.

SAP HANA-Optimized Obects Benefits / Recommendation / Performance Improvements

The main benefits of converting to HANA-optimized DSO

Significantly faster activation

Faster reporting on DataStore object data

Broader adoption of DataStore object

Reporting on granular DataStore object data

The main benefits of converting to HANA-optimized InfoCube

Reporting Aspects

• Reporting directly on

DataStore objects

• No replication to

InfoCubes / BWA

• Significant reduction of

TCO/TCD and load

time improvements


SAP HANA-optimized DataStore object Do we still need InfoCube?

Reporting directly on DataStore Objects

Query performance is similar to InfoCube (with same granularity)

“SID-flag on” -> optimized HANA Calculation Engine access

InfoCube still required

Transformations (not only data aggregation) or multiple DSO feeds into a

cube

NCUM key figures

Integrated planning only on transactional InfoCube

external write-interface (RSDRI) only works for InfoCubes

DataStore Object still limited to 16 keys
