On Exception

BPMN Intermediate Event with Exception

The Intermediate Event with Exception represents the type of event that interrupts a process flow when an exception occurs. It is denoted by the symbol for electric current (indicating hazard) superimposed on the Intermediate Event symbol, that is the circle with the double outline.

Mapping of Visio BPMN Event to the AVEVA Work Tasks Activity

The Intermediate Event with the Exception trigger is mapped to the On Exception Activity, which is represented by the standard notation for Intermediate Events, that is a circle with a double outline filled with orange, with the symbol for electric current superimposed on it to denote the exception.

The following mapping will be used during the conversion:

• Intermediate Event with Exception trigger will be mapped to the On Exception Activity.

• If the Target attribute is specified then the activity should not be mapped to the Wait for Exception activity; instead, it should be converted to an On Exception as the Trigger for the Link.

Validation

On Exception activity may be allowed to have no inlinks; in such a case it will be immediately executed after the Start Activity before the Start Activity proceeds to the next logical link.
