I’ll take a shot: Assuming this is a Notes or browser interface, put this @Formula in the Translation event of the field with the alternate name.
DateCompleteFieldName should be the name of the date field on the document that the new document is created from.
ActionItemFieldName should be the name of the action item on the document that the new document is created from.
ActionItemFieldNameAlternate should be the name of the alternate form on the new document.
@if(@isnewdoc & DateCompleteFieldName = “” & ActionItemFieldNameAlternate != “”; ActionItemFieldName; “”)
The form should have inheritance set.
