Can someone please give me the example syntax in a Deluge function for the following? I am able to create a Workflow rule on EDIT which populates a field on a record based on some logic. But I cannot figure out how to do the same thing on CREATE. I suppose the reason for it not working on CREATE is at the time of the new record being added, that record does not yet have an ID. Therefore, there is no way to populate values in a map and do an Update, because that new record does not exist yet. Am I correct?

Is there a way to reference the "about to be created record" in Deluge and map values to fields on CREATE?
