When a Data Warehouse report fails we are not notified. We have to check the Request Manager at random times to try to see if it is still processing or if it failed. And when it did fail, we are not told why. A better error message in the UI (and sent in an email) would be useful. Also an automatic resubmit of the report if the error was not due to something on my end would be good. I obviously want the report, so I should not have to resubmit it myself.
