The SAP NetWeaver integration platform offers components for integrating SAP systems and systems from other manufacturers in the area of Process Integration. Integration includes not only the exchange of data, but also the integration of processes that can run locally within a system but can also be defined for multiple systems. SAP is providing the Business Workflow for controlling local processes in a system. Business Workflow is based on clearly defined business objects and enables the inclusion of employees when business processes are processed. Since release SAP R/3 4.6, Business Workflow has been able to work with the Internet as the communication structure and Web-based applications for transferring information. The workflows that already exist can, of course, continue to run and be modified.
