Abstract: The present invention relates in a broad aspect to a method for conducting electronic transactions based on business processes, also known as e-Business, by the use of software. By providing a central configuration tool, the invention enables an automatic generation of a central transaction kernel used to integrate all business processes and further integrate to external systems. Thereby, a routing on business process level is obtained. The present invention is particularly useful for e-Business, but it is relevant for all areas of electronic transaction based processes. Also, a synchronous to asynchronous mechanism is introduced that allows plug-in of different communication and formatting components.
