BPMN Activities Reference

Home > BPMN Diagrams Procedures and Reference > BPMN Activities Reference

Activity Flow Objects indicate where work is performed, and an Activity can be a regular task or a subprocess. iGrafx supports all of the indicators specified by the BPMN standard that can be displayed in a BPMN activity shape.

Activity flow objects of type Task or Subprocess may have various advanced behaviors associated with them, including Repeat (Loop) behavior, Multi-Instance, Ad-hoc, and Business Transaction. In addition, boundary events (exception flow) are also permitted on Activities. To set activity options and behavior, see Properties dialog box - BPMN Guide page

The activities with indicators for advanced behaviors are shown below:.

A loop is a sequential repetition of a task within an activity shape.

A multi-instance parallel task is a simultaneous repetition of a task within an activity shape.

A multi-instance sequential task is a sequential repetition of a task within an activity shape.

Ad-hoc specifies that activities in a subprocess are not controlled or sequenced in a particular order.

A business transaction is a special type of subprocess that can use cancel events if needed.

In addition to the standard activity behavior such as duration or cost, you can specify an activity to be a subprocess represented by a separate diagram, or an embedded subprocess that shows subprocess steps in its parent diagram. You may also define a ‘Call Activity,’ which is a ‘Global’ task or process, and is shown with a thick border line. Finally, you may also create Event Subprocesses for event handling. For procedures on how to create subprocesses and exception flows, please see BPMN Flows, Processes, and Behaviors.
