Inter-organizational cooperation has become increasingly important in firms` strategies. This book provides a brief introduction to the theory of cooperation and the foundations of logistics, service management, and supply chain management. The main focus of the book, however, is to examine the use of SAP systems for supporting inter-organizational cooperation (in particular supply chain coordination). The authors present both well-known logistics solutions, e. g. EDI, and the implementations of state-of-the-art supply chain solutions using SAP systems such as mySAP.com, SAP APO, SAP LES, SAP BBP, SAP Business Information Warehouse, and Internet Applications. In particular, the book contains a number of case studies which show the application of the systems in practice.
