First of all, the entire process to be monitored by PPM is modeled as an EPC in the application system using the real activity flow. When creating the process, ensure that all system events occurring are modeled in the EPC as events of a preceding function. Organizational units should be specified at the functions.
For each overall process, create a separate group with a sub-group for the process fragment definitions. Model an EPC for the overall process and a further EPC for each fragment in the sub-group.
Modeling guidelines for the overall process
