This book is about running modern industrial enterprises with the help of information systems. Enterprise resource planning (ERP) is the core of business informa­tion processing. An ERP system is the backbone of most companies' information systems landscape. All major business pro­cesses are han­dled with the help of this system. Supply chain management (SCM) looks beyond the individual company, taking into account that enterprises are increasingly concen­trating on their core com­petencies, leaving other activities to suppliers. With the growing dependency on the partners, effective supply chains have become as important for a com­pany's suc­cess as efficient in-house processes. This book covers typical business processes and shows how these processes are implemented. Examples are presented using the leading systems on the market – SAP ERP and SAP SCM. In this way, the reader can understand how business processes are actually carried out "in the real world".
