Hi I have a universe which is converted to . Unx and it's working fine when u want to create webi reports on it . But when I am trying to make modifications to the universe in IDT, and do the integrity check, it says all the tables which are currently in data foundation are missing in the database... But I have checked the database .. The tables are there .. I checked the same universe in its unv form in udt and it still gives the same error upon integrity check .. Any ideas??
