NetWeaver BW Running on Classical DBTypical Challenges

Challenges

Business User Dissatisfaction Long wait times, slow reporting, not optimal to meet needs of business users

Real-Time Data Access Traditional latency issues in getting timely information

Planning Performance Planning speed slow due to bottleneck of reading & writing data to/from a classical database

Loading Performance Challenging loading windows; loading and consolidation of data not optimal

Remodeling Effort Complex and difficult to apply structural changes quickly enough to meet business user requests

Performance Optimization Requires management of database like indexes, aggregates and DBA operations as well as management of BWA

IT Responsiveness High IT workloads, restricted self-service capabilities, complex modeling; IT becomes the bottleneck

Third level text Second level text

• First level text

SAP contentSource - SAP BW on HANA Overview by Christian Tauber –March, 2013

14

Leaner data models – avoid layers modelled for performance boosting Plan and Report at a level of granularity not possible before – like SKU level

instead of Store level Being more agile to business processes changes – quickly remodel your data

flow according to your business needs BW Workspaces – Combine spreadsheets with BW data on the fly, without

IT help Use sophisticated analytics using BI 4.x that was not possible before BW

worked on HANA – like Lumira, Predictive Analytics, Design Studio

Use BPC on HANA and PAK for real time planning on Hana Use Hana as an analytics platform – across business suite (SHAF), BW on

HANA and Data marts on HANA – to combine strategic data with operational data

What Is The Value Proposition Of SAP NetWeaver BW Powered by SAP HANA (Beyond Speed)?

15

Customer Value of BW powered by SAP HANA

1. Supercharged BW with Dramatically Improved Performance Business: Improved decision making, faster reporting, and the most up-to-date

information IT: Faster data loading and decreased data latency

2. Simplified Administration and Streamlined Landscape Business: Reporting requests executed faster and minimal IT involvement IT: Reduced administration and lower TCO

• Unlock The Power of Your Data Across The Enterprise Business: Self-service access to all information at the most granular level IT: Simplified IT workload with easy access to operational data marts

1. Preserve Your BW Investment without Disruption Business: Minimal training impact to business users and administrators IT: Migration without disruption of your BW application

Myth Busters on BW on HANA Costs and ValueWhat We’ll Cover

• We already have SAP BWA ?• Suite on HANA will make BW redundant • BW on HANA is very expensive

25

• BWA is redundant if BW on Hana is used• Query acceleration in BW on Hana is comparable or better than BWA• Unlike BWA, there is no need in BW on Hana to build index after a data

load. All data is immediately available for reporting after load and DSO activation

• BWA accelerates reports only on pre-selected infoproviders , where as BW on Hana accelerates all reports on BW

• BW on Hana has significantly better performance on load performance, which BWA does not help with

• Please check with your HW partner and SAP Account executive to see how you can protect some of the BWA investments in HW and Licenses

Why Move To SAP NetWeaver BW Powered by SAP HANA If We Have the SAP BW Accelerator?

26

Do We Need BW Powered by SAP HANA If We Also Have Business Suite On SAP HANA ?

SAP HANA Analytics Foundation

Upgrade,…

46

ROI driven migration approach: Illustrative Scenarios Scale of Business -> Small Medium Large

Sidecar

a. Old installation that needs significant clean upb. Need for process/data re-design and infra revampc. Poor BW adoption

Big Bang

a. Need fast ROI b. Need coverage of all scenarios instead of piecemeal/selected scenariosc. Willing to bear downtime instead of spending for a parallel installation

Parallel Deployment

a. Old, large , mature installationb. High user base, minimal tolerance for prod downtimec. BW adoption is high

47

• Before Migration, We suggest that some data clean up should be done• See recommendations in cook book

https://cookbook.experiencesaphana.com/bw/deploying-bw-on-hana/preparation/system-housekeeping/

• Make use of multi-temperature storage concept for BW• Hot data, frequently used for read/write, in RAM• Warm data, infrequently used, in Disk• Cold data, sporadically used, in NLS

• SAP delivered Sybase IQ NLS solution is now available for BW 7.3 SP09. This solutions does not need any third party solution or middleware

What Should We Do About Old Data In SAP NetWeaver BW?
