Understanding SAP R3 A Tutorial for Computer Scientists Florian Matthes Stephan Ziemer Technical University Hamburg-Harburg, Germany http:www.sts.tu-harburg.de f.matthes March 1998 R 1.0 Abstract SAP is the market leader for integrated business administration systems, and its SAP R3 product is a comprehensive enterprise resource planning software system which integrates modules for nance, material management, sales and distribution, etc. Despite its interna- tional commercial success, the models, languages and architecture of this system are to a large degree unknown to computer scientists. The goal of this tutorial is to present the distributed system architecture, the data model, the database programming language, the transaction and process model and the system evo- lution concepts of SAP R3 from a computer science perspective and to relate them to estab- lished database and distributed system concepts. The presentation will help attendees under- stand how SAP R3 relates to their own research and development work and will provide a well-structured foundation for a further study of SAP R3s innovative system concepts.
