I have classified the null values for the s.campaign variable with "Direct Traffic" in one of my classification fields. This works flawlessly in Analysis Workspace as well as data feeds, but it does not seem to work with Data Warehouse exports. All unclassified and direct traffic gets grouped together in exports if I try to use the classification to breakdown some other variable. My "Direct Traffic" classification doesn't show up.
Is this expected, does Data Warehouse somehow read this classification on a null campaign variable differently than other Adobe products?
