| # Introduction How to set up the Master Data to build an enterprise model. This chapter identifies and explains the mandatory and optional sessions in the Master Data. The place and function of Master Data The Master Data is mainly used to set up an operational environment. You can create and maintain the enterprise modeler building blocks, such as business processes, employee groups, and business control diagrams. In the Master Data you can define versions, components, and parameters. The Master Data contains sessions that deal with version authorizations, parameter maintenance, and responsibility codes. You can add master data while modeling, but some of the data used in the models must first be defined in the Master Data. This does not mean each time a business model is created new master data must be defined; the master data already defined can be used in an unlimited number of business models. |
