Event unknown (Message: CWWBE0037E)

An attempt to send an event to a process instance or to start a new process instance results in a "CWWBE0037E: Event unknown." exception.

Reason

A common reason for this error is that a message is sent to a process but the receive or pick activity has already been navigated, so the message cannot be consumed by this process instance again.

Resolution

To correct this problem:
  • If the event is supposed to be consumed by an existing process instance, you must pass correlation set values that match an existing process instance which has not yet navigated the corresponding receive or pick activity.
  • If the event is supposed to start a new process instance, the correlation set values must not match an existing process instance.

For more information about using correlation sets in business processes, see technote 1171649.
