[Throw message] intermediate event

The [Throw message] intermediate event (Fig. 1) is used to broadcast messages within a current business process. The generated message will activate a [Wait for message] element or a [Message] start element within the same process.

For example, the “Invoice is paid” message is thrown by the [Throw message] intermediate event within a business process for checking invoice payments. This message triggers all “Invoice is paid” [Wait for message] events in this process (Fig. 2).

The same [Throw message] event can initiate event sub-processes within the current business process (Fig. 3)

The message generated by the [Throw message] event cannot be sent to a different process.

[Throw message] intermediate event operation

Activation

When the element incoming flow is activated, the [Throw message] event generates a specific message that triggers all [Wait for message] elements within the process that are configured accordingly to catch this specified message.

Execution

After broadcasting the message, the [Throw message] element activates its outgoing flows.
