The documentation goes on to cover this case as well, just a bit further down:

Apologies as I haven't dealt with this stuff myself in a while, so I don't have any live examples (that i know of) in my environment to provide you with any additional clarification.

Edit to add: i whipped up a single-model tester for this and verified it myself.

Step 1: set a new mapping on the Send event (here named "target", it can be whatever name and type you want)

Step 2: on the Setup tab of the Receive node, create a Condition or Expression (or import the condition from "Import Custom Properties", although all this does is give you the message mapping names pre-staged, which you can do yourself eventually), and set the node condition to execute when the target is the correct value:

Thanks ,

I already managed to send a message to a specific process, but now I have the need to send a message to a specific process and at the same time to a specific receive message event. Try this configuration and what happens is that the message arrives to all active instances and to all receive message events.

Any ideas ?

AFAIK the process instance ID is set in the "DestinationProcessID" parameter.

Unfortunately the node's configuration labels are a little vague on this aspect, but the official appian documentation is a little more clear:

So whilst you have to configure a "listener" (receive message) in the process model (so that all instances can receive a message) you can send a message to a specific instance. You do this by determining the target ProcessId. In order to get the instance ProcessId you need to create a process Report, and your process that sends the message needs to have a value that is unique to your target process instance that is visible to the process report - e.g. a unique business value.

You can directly target a specific instance.
