EPC to BPMN transformation rules

The following section describes the rules according to which a business process model of type EPC is transformed to a diagram of type Enterprise BPMN collaboration diagram or BPMN collaboration diagram (BPMN 2.0) depending on the option selected.

If the transformation generates an Enterprise BPMN collaboration diagram, all service tasks are generated in a lane of the application system tpye. All manual tasks are generated in a lane of the type of the relevant organizational element.

If the transformation generates a BPMN collaboration diagram (2.0), all Application system type objects are placed in the default (system) lane.
