I have DESKI report and certain date column is getting inserted as a default date 1/1/753 12:01:00 AM. I would like to show as null whever the value is above. This i tried using with alerters, but i applied with decode statement in universe. Some reason, even though i decoded in universe, still showing the value as 1/1/1753 12;01:00 AM. Please advice how to make it null.
