Source: SAP SAP BW/4HANA THE NEXT GENERATION DATA WAREHOUSE
CORE BENEFITS OF BW/4HANA Simplicity Get up and running sooner and keep running at lower cost Reduce development efforts Openness Work with HANA in BW mode, or in native SQL mode, or both Easier access to all information Modern Interface Simplify access for everyone, not just database experts New UI for all users High Performance Leverage huge amounts of data in real time for competitive advantage 10-100x faster query performance
BW/4HANA: SIMPLIFIED DATA STRUCTURES Number of modelling object types reduced from 10 to 4 No complex data structures (extended star schema) Field or InfoObject based modelling Greater control of data persistency and virtualization Support for external, structured and unstructured data Composite Provider Open ODS View Advanced DSO InfoObject
BW MODELING TOOLS IN ECLIPSE Delivered and planned Eclipse Editors in SAP BW/4HANA and SAP BW
BW/4HANA: SIMPLIFIED DATA FLOWS From Layered Scalable Architecture (LSA) to LSA++ Report at any layer of the Data Warehouse with speed and flexibility Virtually combine data across layers Business and service level driven Combining bottom-up and topdown modelling approaches allows for agile and flexible development Source: SAP
SIMPLE DATA INTEGRATION Leverages SAP HANA EIM to provide new data provisioning opportunities Replicate data in realtime (EIM-replication or SLT) Access data virtually Load data using optimized processing Or automatically switch between the different methods Source: SAP
DATA TIERING CONCEPT
SIMPLIFIED SOURCE SYSTEMS DB Connect UD Connect SAP Data Services BAPI/Partner HANA Source System ODP Extractors BW Source System Types reduced from 10 to 4: HANA source system ODP source system File source system Big Data source system
OPERATIONAL DATA PROVISIONING (ODP) Operational Data Provisioning provides a technical infrastructure that supports Data extraction and replication scenarios between various sources (ODP Providers) and target application (ODP Consumers). It supports delta mechanisms and queueing of data in the so called Operational Delta Queue (ODQ). The ODP Framework is installed on the respective source system independently from SAP BW or SAP BW/4HANA (eg. in PI_BASIS) With the ODP Source System in SAP BW or SAP BW/4HANA data can get directly processed from the ODQ to data targets (Advanced DataStore Objects / InfoObjects) without using the Persistent Staging Area (obsolete in SAP BW/4HANA)
THE THREE APPROACH-STRATEGY FOR SAP HANA DATA WAREHOUSING

BUSINESS VALUE DRIVERS FOR BW/4HANA Easy Integration of Big Data Scenarios IT Cost Reduction, Development Productivity Development Productivity, Faster Time to Value for the Business New Capabilities, Reduction of TCO
STRATEGY TO MOVE TO BW/4HANA Preparing your system Options for migration
HOW TO PREPARE YOUR CURRENT SYSTEM Check Your BW System Before /After Migrating to SAP HANA Size via Automated Sizing Tool Lower TCO by Leveraging Non-active Data Concept and Off-loading Data to Near-line Storage Perform Housekeeping Task Regularly Leverage Automated Task Lists Validate SAP HANA Configuration, Check Table Consistency and Monitor Delta Merge Convert Data Flows and InfoProviders Check Best Practices for ABAP on HANA Check SAP Note 1909597

GREENFIELD IMPLEMENTATION Also referred to as greenfield approach, this path start by installing a brand new SAP BW/4HANA system. There is a new automated task list available to simplify the basic system setup tasks, like creating and configuring the SAP BW/4HANA background user, setting the SAP BW/4HANA client and installing the essential technical content. There are two basic options for configuring your new SAP BW/4HANA system. Either it can begin from scratch, connect any data sources that could be a legacy data warehouse Or any other data source available in your enterprise and start modeling the data warehouse. It is highly recommend following our layer scalable architecture framework (LSA++). To start from an existing SAP Business Warehouse (BW) system, certain configuration and data models can be transported from your existing landscape to SAP BW/4HANA.
CONSOLIDATE AND SIMPLIFY
LANDSCAPE SIMPLIFICATION This is to optimize more complex data warehousing landscapes resulting in a single, global SAP BW/4HANA system. One reason could be that there are multiple legacy or SAP BW systems which is required to consolidate on the mighty SAP HANA platform. Another could be to carve out selected data models or flows into an existing SAP BW/4HANA system. One of the innovative tools is the System Comparison Workbench which can show the differences between several regional SAP BW systems and help define a strategy to integrate these into a global data model.
LESSONS LEARNT A clear governance and guidance needs to be defined EDW Layer should be either in BW or HANA Usage of BWonHana Objects and SQL-Programming needs some experience Data streaming requires new skills and has some complexity Performance is not always a "Quick Win"
KEY TAKEAWAYS BW/4HANA is an open DWH and combines the functionality of a relational DWH and a BW Reduction of BW objects leads to faster implementation SQL based transformations are stabile and fast Data Streaming and Flow Graphs offer new use cases With BWonHANA we can reload our entire data into the DWH within 1 weekend
