I have been checking on the 'Ad Hoc Dataset Row Limit' and it seems to be that the limit applies however the report is run (i.e. run manually or scheduled). There is an argument that maybe the limit should not be applied if the report is scheduled, as this could be run out-of-hours and therefore less of a problem. However, if the limit is applied across the board, that is fine but could someone just confirm for me that this is what is meant to happen? Many thanks
