Activities

When the modeler places an activity symbol, the software sets the corresponding value of the ARIS attribute type Activity type (AT_BPMN_ACTIVITY_TYPE). This activity type controls the correct behavior of the symbol. E. g: A subprocess may have embedded flow elements, a task must not; a call activity may reference another task or process, tasks and subprocesses must not.
