What is SAP BW/4HANA?

SAP BW/4HANA stands for Business Warehouse for SAP HANA and represents the latest generation of SAP’s data warehouse solutions. It is a state-of-the-art data management and analytics platform designed speci­fi­cally for the HANA database. This platform enables companies to integrate, process and analyze large amounts of data from various sources, with a parti­cular focus on real-time data analysis and flexi­bility. The core features of SAP BW/4HANA include advanced data modeling, efficient data management and storage, and powerful analytics tools. By using the SAP HANA database, SAP BW/4HANA benefits from signi­fi­cantly improved perfor­mance. This perfor­mance increase comes from SAP HANA’s in-memory technology, which enables quick access to large amounts of data and accele­rated data processing.

Real-time data analysis with SAP BW/4HANA

SAP BW/4HANA is an advanced data warehouse solution speci­fi­cally designed for real-time data analysis. It enables companies to gain instant access to relevant business data and thus make faster and more informed decisions. Real-time data analysis in SAP BW/4HANA is made possible by its tight integration with the SAP HANA database. This integration provides powerful in-memory technology that enables large volumes of data to be processed in real time. In addition, SAP BW/4HANA is able to seamlessly integrate data from various sources, both from other SAP appli­ca­tions and from non-SAP systems. This is achieved through advanced data management and integration tools that enable efficient and flexible data collection and processing. The platform supports the integration of various data types, including struc­tured and unstruc­tured data, which expands data diversity and analysis options.

Advan­tages of real-time data analysis

Real-time data analytics, as enabled by SAP BW/4HANA, offers a number of business benefits that span across different business areas. One of the main benefits is the ability to make faster and more informed decisions. This is parti­cu­larly useful in dynamic business environ­ments where delays in decision making can be costly. Real-time data analytics also enables conti­nuous monitoring and optimization of production processes, insights into customer behavior, and opera­tional efficiency. These benefits span across different indus­tries and help increase compe­ti­ti­veness.

Archi­tec­tural aspects of SAP BW/4HANA

The archi­tecture of SAP BW/4HANA is speci­fi­cally designed to support and optimize real-time data processing. This modern data warehouse solution is based on SAP HANA database technology, which enables high-speed data processing and analysis. The in-memory technology of the SAP HANA database makes it possible to hold large amounts of data directly in memory, which signi­fi­cantly reduces access times to the data. In addition, SAP BW/4HANA supports simplified data modeling and expanded possi­bi­lities for integrating data from various sources, both SAP and non-SAP systems. This is crucial for obtaining a compre­hensive picture of business activities in real time.

Imple­men­tation and best practices

When imple­menting SAP BW/4HANA, there are some key conside­ra­tions and best practices to follow to maximize efficiency and perfor­mance. These include needs analysis and goal setting, technical prepa­ration, data migration and integration, training and change management, agile imple­men­tation methods, perfor­mance optimization, and regular maintenance and updates. These measures help ensure the successful imple­men­tation and use of SAP BW/4HANA.

Case studies and appli­cation scenarios

The successful imple­men­tation of real-time data analytics with SAP BW/4HANA is demons­trated through concrete case studies and appli­cation scenarios. These examples illus­trate how companies have improved their data processing and analysis capabi­lities by imple­menting SAP BW/4HANA to make faster and more informed business decisions. Adapt­ation to specific business needs, integration into existing system landscapes and focus on data quality are important aspects of successful imple­men­ta­tions.


In summary, SAP BW/4HANA is a powerful platform for real-time data warehousing that helps companies to be data-driven and agile. Real-time data analytics will play an incre­asingly important role in the future, and SAP BW/4HANA is well positioned to meet these needs and be conti­nuously developed to keep pace with the changing requi­re­ments of the digital economy.

Frequently asked questions and answers

What are the advan­tages of modeling with SAP BW/4HANA compared to previous versions?

Modeling with SAP BW/4HANA offers several advan­tages compared to previous versions. The number of development objects has been reduced from ten to just four, which simplifies modeling. In addition, the optional field-based modeling enables faster and needs-based development, as the semantics no longer have to be defined top-down in advance. The input aDSO can be generated, which enables initial reporting in a few minutes/hours. This signi­fi­cantly speeds up development processes. Furthermore, the dynamic star schema has been intro­duced, which signi­fi­cantly increases the flexi­bility in the development of data models. The semantics have been separated from persis­tence, and the composite provider associates fields or InfoOb­jects in InfoPro­viders with persistent or virtually modeled master data. These impro­ve­ments make modeling with SAP BW/4HANA more efficient and flexible.

What migration options does SAP offer for existing customers of BW systems?

With SAP BW/4HANA, development will continue under BW 7.5. The modeling of the data warehouse is incre­asingly taking place in Eclipse. Although this can be a change for experi­enced SAP BW developers, the BW/4 HANA Cockpit offers an easy-to-under­stand web-based interface that bundles all functions for the adminis­tration and monitoring of the BW system. It contains processes that are fully optimized for SAP HANA and in which enormous amounts of data can be processed in real time.

How does SAP BW/4HANA support development under BW 7.5?

SAP offers three migration options for existing customers of BW systems to facilitate the transition to BW/4HANA. These options make it possible to migrate existing BW systems while retaining previous invest­ments. The migration options are designed to prepare the existing BW systems for future requi­re­ments and to overcome the problems that have arisen due to systems that have grown over time. The right archi­tecture and development metho­dology are essential success factors for a successful migration to BW/4HANA.
