This document provides an overview of SAP Business Warehouse (BW) and how to generate reports from BW. It explains that BW allows flexible analysis of large amounts of business data and creation of dynamic reports. Data is transferred from SAP servers to the BW server, where it is stored in high-performance databases called infocubes. Users can then generate reports on various business functions like logistics, sales, finance, and more by logging into BW and using the Business Explorer tool within Microsoft Excel. The training covers logging into BW, selecting variables to filter reports, and generating sample customer master reports.
