Business Processes: Integrated Business processes are linked: The R/3 System integrates all activities related to a process in workflows, replacing conventional work structures with a cross-functional approach. The SAP Reference Model is the basis for the simple and efficient representation of business processes with R/3. The Reference Model applies the methods of Event-Controlled Process Chains (EPCs) to clearly represent the functionality and scope of the software. The SAP Business Navigator contains complete descriptions of the data and process models offered by SAP. In the initial stage, you can use the R/3 reference processes to compare your business areas with the solutions offered by SAP on a general level. Data and process models allow you to look at different views of business flows in the R/3 System, and the models make it easier for you to get an overview of the variants and possible combinations of the more than 850 predefined business processes. The integration of the reference models in the R/3 Repository gives customers the security of knowing that the models offered can all be processed with the R/3 System. The support of the easy-to-use Business Navigator lets you immediately analyze your own business processes, get to know the design variants offered by the R/3 System, and to make an informed decision for your company.
