If you are responsible for the administration of an SAP R/3 system, or would like to know more about it, this book will show you how to exploit the potential of the R/3 system to maximum effect. SAP R/3 Administration provides a detailed explanation of the technological basis and the development environment of the R/3 system and practical guidance on performance tuning. This book provides detailed coverage of the organization and operation of the R/3 system and the transport system that monitors, coordinates and logs access to system data. It explains the fundamentals of ABAP/4, the programming language at the heart of the SAP R/3 system, and shows how to program simple reports and understand ABAP/4 programs. With this book you will learn how to: * monitor and maintain a live R/3 system * understand different types of R/3 systems, exchange objects between these systems and control modifications to the user * use the CCMS (computer center management system) to observe R/3 operation and evaluate and avoid potential problems early on. The authors have drawn on their own considerable experience in customer support to provide this comprehensive, practical guide to the administration and performance tuning of the SAP R/3 system. While you do not have to have any prior knowledge of the R/3 system to read this book, it is assumed that you will have some previous experience of relational database management systems and SQL. An accompanying disk contains R/3 transport data for the examples featured in the book and is described in Appendix G.
