This book is a how-to guide. It uses step-by-step procedures with captured screen shots to illustrate SAP BW’s functionalities. Although the book focuses on the core SAP BW technology, it also discusses other SAP technologies, such as Basis, ABAP (Advanced Business Application Programming), and ALE (Application Link Enabling) when necessary. It does not, however, discuss third-party reporting tools and BAPI (Business Application Programming Interface). Intended Audience This book is written for BW implementation teams and other individuals who need a product to understand the data warehousing concept. Prerequisites BW is built on the Basis 3-tier architecture and coded in the ABAP language. ALE and BAPI are used to link BW with SAP systems (R/3 or BW) and non-SAP systems. This book, however, does not require readers have knowledge in these areas. Instead, BW has made the development of a data warehouse so easy that people with minimal experience in database design and computer programming can use it. Book Structure This book is organized into two parts: Part I contains guided tours. We start from a simplified business scenario, then illustrate how to create an InfoCube, load data into the InfoCube, check the accuracy of the loaded data, create queries to generate reports, and manage user authorization. Part II focuses on advanced topics, such as InfoCube design techniques, aggregates, multi-cubes, operational data store (ODS), Business Content, generic R/3 data extraction, data maintenance, performance tuning, and object transport. The appendices introduce ASAP (Accelerated SAP) for BW, one of the derivatives of the ASAP implementation methodology developed by SAP, and give an overview of the Basis 3-tier architecture.
