SAP BW on HANA - Overview

SAP Business Warehouse (SAP BW) powered by SAP HANA supports you to promote data review by destroying data via a Data Warehouse (DW) thorough analytical reporting and statistical analysis. Also, achieve key occasions like real-time data synthesis and data modeling, and hence real-time SAP Business Intelligence (SAP BI) listing on a large amount of data in the database.

SAP BW proceeds to act as a powerful data warehouse tool to combine master data and give extensible reporting options. With SAP BW on HANA system as a database, you can use a combination of DW capabilities with the fast in-memory database to achieve performance enhancements and extraordinary modeling abilities.

HANA in-memory database is much faster as compared to other common databases like Oracle, SQL Server, and hence DW performs much faster when powered by HANA as database beneath it. It combines the power of both the tools - BW Modeling and HANA in-memory computing engine to process huge amounts of data.


SAP BW on HANA supports various exceptional databases and reporting capabilities that are not possible using other databases - like transformations and DSOs are moved to HANA database to provide much faster processing of data, data load performance, query processing and optimization, exceptional HANA modeling capabilities, etc.

SAP BW is an enterprise data warehouse product by SAP which can integrate and transform business information from any possible source system. SAP BW using SAP HANA was the first application by SAP to run entirely on SAP HANA, and SAP BW 7.5 is the latest update in SAP BW. The SAP is known for Data Warehousing worldwide and clients will gain immensely from the planning functions, query runtime, and improvements in data load seen in this product. This has highly simplified data modeling and reduced Info Provider. Also, all data modeling is done within a new user interface which is distinct across all modeling tools.

SAP BW powered by SAP HANA refers to using BW software suite on top of HANA database. This functionality explores all the key features of HANA database technologies and uses BW as a modeling tool for data modeling and analytical reporting. BW software supports various databases like Oracle, Microsoft, IBM DB2, Teradata, and many more. BW on HANA suggests that you are using HANA as a database for BW data modeling capabilities and no other database is required.

Drawbacks of Using SAP BW on HANA with Other Databases

Following are the drawbacks when you use SAP BW with other databases such as Oracle, SQL Server, and IBM DB2.

Real-time Reporting

Using BW with other databases, you can’t perform real-time reporting as real-time data is not available in the data warehouse. Data is moved to Business Warehouse in batches and hence is not available for real-time reporting.

Implementing Structural Changes

To implement any structure changes, it is very time-consuming and a tough task as compatibility is not available with other DB vendors. To implement any structural changes in Business Warehouse, it takes 2-12 months’ time.

Report Performance

You have to perform report performance optimization and tuning for each application.


Data in Business Warehouse is aggregated and materialized and you can’t get the data at different granularity level. HANA supports aggregations on the fly when the report is executed.

Using SAP BW powered by SAP HANA, you can find the following benefits –

·         Best achievement in analytical reporting and data storing using HANA in-memory database skills. All BW roles performed in SAP HANA profits from the in-memory database and calculation engines for faster data processing.
·         With HANA optimized objectives, you can implement complicated queries, detailed analysis, high data volume, and aggregations efficiently.
·         All existing BI tools such as BEx, Business Objects BI reporting tools, and Microsoft Excel are directly supported by SAP BW on HANA.
·         SAP HANA provides the high level of data compression. Standard storage of tables requires less storage type and hence provides lower Total Cost of Ownership (TCO).
·         Business Warehouse Accelerator (BWA) is not required while using HANA underneath BW.
·         You don’t need aggregated tables and HANA supports on-the-fly aggregations.
·         It has simplified data modeling by using in-memory-optimized objects. There is no need to load BWA index.
·         When you use SAP BW on HANA, the following processes are not required −

Ø  Rolling Up Filled Aggregates
Ø  Filling of New Aggregates
Ø  Adjust Time-Dependent Aggregates
Ø  Construct Database Statistics
Ø  Build Index
Ø  Delete Index
