The Message start event (Fig. 1) is used to activate event sub-processes within a parent business process. Such event sub-processes are run through the Throw message intermediate event in the corresponding parent business process.
For example, your sales process can include an event sub-process during which the list of ordered products is modified. The customer can modify the list of ordered products at any time, any number of times. Each case of modifying the order must be followed with a Throw message event, which would activate the Message start event of the order modification event sub-process.
[Message] start event operation

Activation |
The element is triggered by a Throw message event on the same business process diagram. |

Execution |
When activated, the Message start event initiates the event sub-process. The Message start event activates its outgoing flows and enables execution of the other actions in the event sub-process. Same Message start event can be triggered multiple times within a process instance. |

Select this checkbox, if you want any “User action” elements activated with the outgoing flows of the current element to run “in the background”.
