In this paper we present a conception for an integration of ERP- and CSCW-Systems. Several benefits will be shown, like a complete GUI integration, a flexible web access and even possibilities for reduced license fees. The coupling of the former semantic disjointed worlds of ERP- and CSCW-Systems can be done on different levels of abstraction. Although it is possible to exchange data between applications via conservative technologies like electronic data exchange (EDI), file transfer or direct database access, a common pool of business transactions and objects leads to more effective applications. Interoperability technologies like CORBA can be used to integrate applications from an perspective on the object level. The authors summarise their experiences with typical applications of standalone CSCW- and ERP-Systems and therefore intend to guide the reader towards the benefits of the integration of both worlds.
