Modeling Message Flows
Message flows are used for communication between participants of a process.
A collaboration with at least two participants exists.
Message flows can only be modeled between various participants of a collaboration and/or flow nodes in various participants. The following elements can be a message flow's source and/or target element:
- Participant
- Activity
- Event
The message flow icon is then only shown for these elements in the carousel and only within a collaboration.
Message flows can only be modeled in a collaboration if a participant's process is only shown as a referencing view and if the collaboration itself is shown as a defining view.
A message can be assigned to a message flow.
- Use the carousel to create a message flow.
The message flow is created. If a message flow starts or ends at a message event, send task or receive task and if a message is already assigned to this element, the same message is then automatically assigned to the message flow.
- To explicitly assign a message to a message flow, drag the message from the Model Content or another tool window and drop it on the message flow.
It is also possible to make the assignment in the Properties window.The message is assigned and shown next to the message flow.
