BW/4 HANA - Overview

BW/4 HANA  -Next generation

BW/4 HANA

* Introduced in 2016
* Deeper integration with Big Data
* it requires BW 7.5 SP4
* Logical continuation
* not a part of NetWeaver
* Run on only SAP HANA
* Certain netWeaver is part(like transport..etc)

* Simplicity

* reducing modelling objects
* will have only 4 objects (earlier it was 10 objects)
* 2 objects for persistence (i.e ADSO & Infocube)
       * 2 objects persistence (ODS & Composite provider)
* leverage with 4 objects only

* Architecture
* less persistent layers
       * Reduced development efforts because less layers
       * every layer can be used for query
* combined layers from various layers

* Operations
* integration is tighter
* cloud deployments
   -->HEC
   -->AMAZON Webservices
   -->Microsoft

* Exposing data for SQL Consumption
* Automated generated views
* calculated views
* Automatic push down from BW to HANA

* Sources
*ECC,ASSE,SAP HANA
* Hive
* Face BOOK
* Excell
* Twitter
* SOAP
* Files
* 3rd RDBMS
* HADOOP
* TEXT
* Structured
* Social Media
* Email  to EIM--> (Smart Data Integration)-->SAP HANA Source system
        * SAP Source system
   SAP Sources -->ODQ (Extractor logic) --> oDP Source system

BusinessObjets for Business Users
* SAP BO Cloud (newly released)
* SAP BO Design studio
* SAP BO Analysis

Modern UI For modelling and Administration

Performance
push down in hana db
OLAP functionalities are push down
leveraging performance inside BW
Bring libraries and Algorithm

Advantages
* newly released
* not legal successor for existing BW
* focus on hana only
* enable flexible data warehouse Architecture (less layer,persistence, more virtualization,          combination..etc)
* Simplifies Data warehouse modelling and Administration

Functional overview
Data flow modelling
* Graphical data flow which looks like whiteboard
* BW objects with drag and drop (like
* Central modelling point for modelling point
* modell new and existing data flow, transformations,executed DTP...etc
* extend node for scale out architecture

SAP BW/4 HANA comes with new data flow modelling environment
simplifies management of large data volumes with flexible dynamic tiering concepts

Migration to SAP BW/4HANA

SAPBW on XDB--> SAP BW Powered by hana--> SAP BW 7.5 Powered by SAP HANA +SAP BW/4HANA start addon --> SAP BW/4HANA

Prerequisites for moving to SAP BW/4HANA 
* only use HANA -Optimized objects
* Only use ODP, HANA, and File source system
* NO 3.X dataflows
* No Bex front end tools/Bex query
* Planning not supported till further notice

Dataflow Transfer tool
* copy complete dataflows
* Automatic generations of SAP HANA-Optimized SAP BW Objects

Old flow --> Datasource ->DSO(STD)-->CUBE--> MP
New(after copy--> Datasource --> ADSO-->ADSP-->Composite provider
captures only dataflow metadata(no data)


Development Roadmap for SAP BW/4HANA
Q3-2016
Cloud deployment (Microsoft,amazon,SAP hec)
Dataflow modeler is easy and intuitive, replacement of DW Workbench modelling perspective
        pushdown all olap to hana (e.g loading master data)


Q1-2017
BW/4HANA Optimized BI Content


Q2-FP 2017
Automated Data life cycle management
based on partition and temperature definition
automatic data placement to extension nodes or NLS(SAP IQ,HADOOP)
parallel loads for master data (based on ADSO like data structures)

2017
Automation of complex Big Dataflows with SAP BW/4 HANA
Tight Coupling between Hadoop & BW/4 HANA Processes
further OLAP Push down
