What BW does

BW consolidates data from many sources into a data warehouse structured for analysis, extracting and transforming data, storing it in layered models, and serving it to reporting and analytics tools. It provides consistent, historical, cross-system reporting beyond what transactional systems offer.

Key capabilities

Extraction (ETL): loading from SAP/non-SAP sources.
Data modelling: layered architecture (LSA++), ADSOs, composite providers.
Reporting: queries consumed by SAC/BEx.
BW/4HANA: the streamlined, HANA-native successor.

How it fits

BW integrates with source systems for data and with analytics tools (SAP Analytics Cloud, Analysis for Office) for consumption. In the modern data landscape it sits alongside SAP Datasphere and embedded S/4HANA analytics, and remains important for enterprise data warehousing.

Learning it

Learn BW through its core processes, its master data and configuration, and its integration with the rest of the SAP landscape. Hands-on practice cements it.

Common pitfalls
