Using the trackId Field
The trackId envelope field can be set by a publishing client application to a unique identifier that will allow the event to be tracked. The use of this envelope field allows an event that is received and then re-published to still be tracked. This envelope field also allows you to track several events that may be associated with a single logical transaction.
Note:
If trackId envelope field is not set, any of the webMethods Broker functions for delivering reply events will automatically set it to the value contained the pubId envelope field.
