BW on HANA at ODAG (Introduction)

� HANA for BW introduced in Q1-Q2/2013 (one of the first swiss customer)

� Application migration: only conversion of traditional Info Cubes to HANA

optimized and activation of IP PAK and BPC on HANA has been performed

� Upgrade to BW 7.4 SP 10 in Jan 2015 the new HANA optimized BW InfoProvider

based on Eclipse in the HANA studio (BWMT) could be used for the first global BI

project

� April 2015: LSA++ architecture approach for the Global Inventory reporting

application was established at ODAG as a new standard!

Latest BW on HANA features in action (Introduction GIR)

Major functionalities:

Global Inventory Risk Report shows:

- Actual stock status per month end in LC/CHF

per reporting unit and location,

per brand and line

per material type

- Slow movers and potential obsolete materials and

financial risks

Motivation/Objectives:

Enhance transparency and effectiveness of inventory management and

reporting (e.g. optimization of stock level per location)

Optimize Net Working Capital (NWC)

LSA++ Architecture of the GIR Application (overview)

SQL Joins- and Unions via ABAP CDS- Views

Important changes with SAP BW on HANA

� Less diversity in BW objects

� Reduction only to InfoObject-Types: ADSO, Open ODS Views and Composite Provider

� Less objects of data persistence

� LSA++ allows reporting on entry layer data or remotely persisted data (e.g. SDA)

� Data persistence only when necessary, not by default (small Memory size!)

� Less ABAP and more SQL knowledge needed (e.g. CDS-Views)

� SAP GUI BW functionality still is indispensable

� Batch job scheduling / monitoring (Process Chains)

� Roles & authorizations

� Special functionality (BW-IP, APD, special transactions, etc)

� Transformations / very complex transformation logic

� Historisation scenarios (Snapshots for Trend-analysis)

Mixed scenarios (combine BW and HANA native sources)

Benefits of Mixed Scenarios, combination of BW and HANA:

� Increase the agility of the Enterprise Data Warehouse

� Combine the strengths of the SQL oriented approach with an integrated EDW

application

o Flexible, agile modeling through Open ODS

Views (on field based level)

o Capability to enrich data from S/4HANA

Analytics views with BW managed master data

(e.g. hierarchies, Navigation attributes)

o Takes full advantage of BEx reporting

capabilities (e.g. restr. & calc. key figures,

currency conversion, Exceptions, etc.)

o Security handled by BW authorization

S/4 HANA embedded Analytics ( Operational reporting )

• Predefined out of the box analytical content from SAP based on ABAP CDS views

(Virtual data model)

• Content has to be verified (like existing BW content) if it can be used for upcoming

business requirements (matching)

• If an existing delivered CDS view definition will not match, possiblity to enhance the

logic with the help of the HANA studio tools (like ABAP- and modelling view) =>

Knowledge required!

• Non-BW-managed persistence (no ETL processes, InfoProvider are connected to

HANA CDS-views) => like virtual Providers

• User Interface based on FIORI design

CDS

� Challenge - Price list generation � Different SAP price lists as basis

� Material for certain base product only once in

generated price list

� Dependence on existence of TPD2 (Tobacco

Products Directive) information

� Dependence on existence of country specific

pricing

� Solution – ABAP CDS Views� Generation of entries for price list at query

execution time

� No data persistence from Propagation Layer

upwards

� Generation of price lists for any point in time

(historic / present / future)

� No persistence of all possible combinations or

implementation of complex flagging or selection

logic

� Replacement of present tedious and error prone

manual price list variant maintenance

Alternative: CDS Views based on ABAP Managed DB Procedures (NW 7.5)
