BPMN Training Part 13: Event-based Gateway
Chapter Overview
In this training chapter you get familiar with the BPMN event-based gateway.
An event-based gateway is a special kind of exclusive gateway. Like for an exclusive gateway only one of the conditional flow is processed directly after the corresponding event was catched.
Sample BPMN Process Model
Tutorial Model: Automation/Business Process/Tutorial/BPM/EventBasedGateway/UserRegistration
Process Explanation:
-
The process starts with a user task "Request Registration".
-
After the gateway "Is canceled?" the default flow "NO" triggers a message intermediate throw event "Start Moderation" which sends a "Start Moderation" message to the process "Registration Moderation"
-
Then the sequence flow triggers the event-based gateway "Timeout or Registration?"
-
The process is now in a wait state at two events
-
The intermediate timer event, which is configured for a waiting intervall of "3 min"
-
The intermediate message catch event "Receive Notification", which is wating for a message from the process "Registration Moderation"
-
The first event that fires triggers the user task "View Registration Result"
-
The process will then be repeated, if the gateway "Has Retry?" is true, otherwise the process is completed.
