Creating an Execution Model

The content of the execution canvas pane depends on the selected object on the BPMN canvas - three different views are possible:BPMN element. For some elements the execution model must be created manually when you want to add execution, for others a default execution diagram is created automatically. Some BPMN elements allow for no execution at all.
