16.3 - Sending Message Events to Process Models

The release notes for Appian 16.3 contains the following (

Sending Message Events to Process Models
We've deprecated the ability to send messages to process models from the Setup tab in the Send Message Event smart service. Sending message events to process models this way has negative performance impacts.
Use the Start Process Smart Service instead.
The last part implies this is only for start message events, but the body implies it applies to all message events, including intermediate message events. Would someone be able to clarify exactly what is being deprecated? Removing the ability to message process models (and therefore in-flight instances) altogether would be a serious loss of functionality and would place Appian behind its competitors as fa...

@Phil: as you mentioned, rather than targeting a process model, if the process ID is not known, then you can use a process report to find it based on the business data.
Thanks for the feedback - I have passed it on to the Product team.

As mentioned above, there is no loss in functionality because you can either
1. Select one or more Receive Message Events within the process model, or
2. Specify one or more process ids in the DestinationProcessIds field in the data tab, or
3. Use the Start Process smart service to start a process instead of using the Send Message event node.
Existing process models configured to send a message to process models continue to work as before, but we encourage everyone to start moving towards using one of the above options.

Ok - so to be clear, this is a deprecation of messaging a model rather than an intermediate message event in a model?

To pick this up again, what about starting a process as result of an escalation in a user input task? From my understanding of what Annelise said, this is not possible anymore.

@stefan: I'm unclear how it wouldn't be sufficient to just use the Start Process smart service following the escalation, though?

I am talking about an escalation, not an exception. In an escalalation there is no alternative process flow and no way to use this smart service. But for handling escalations we can build very nice solutions IF we can start a process by sending a message to the start node. And exactly this is what my question is about. Anneliese said that we can still send a message to a receive message event. But does this include the start node?

I think the answer is the same - you can send a message to a specific receive message event within a process model, but you won't be able to message the process model itself.
