=Count([??DP1.DO3f??]) is a variable that I can view in an old report, is this some syntax that I am unfamiliar with, or is this possibly an error due to a variable that has been removed.
You’re correct, an object which was used in the earlier might’ve been removed the Result objects in the query, that’s why you see the error.
it seems the object is missing from the universe or from the query. You have to check the universe or just create the variable again. Then its working as before…
