Summary:

Clearing the Communicated Window properties

Content (please ensure you mask any confidential information):

When an activity isn't completed the original day that a Communicated Window is established, we need to clear the values so a new window can be defined the next day the activity is routed to a resource. I've tried multiple placeholders, but, so far, they've all failed with "wrong configuration: unknown label".

Is it possible to clear the Communicated Window properties via Message Scenarios? If so, what is the activity placeholder that should be used in the message subject?
