Abstract: The invention relates to a method that produce a map of a network of supply elements in a production process for a device for planning and/or for monitoring this production process. These supply elements supply a system provider or other supply elements with raw materials, semi-finished products, components and/or services. According to the inventive method, the system suppliers to the system provider first of all provide the required information, in particular obtaining the information for each system supplier about which previous suppliers supply that system supplier. The information which is required from these previous suppliers is then obtained, and after that the information from the suppliers previous to the previous suppliers. This information is used to compose the map of the network. One advantageous refinement defines how the network is traversed in order to set up the map in steps.
