I have been developing a new universe for users on a SQL Server box for the past month and a half. At close of business yesterday when I came to export the universe. I got a message stating "Could Not Export Universe" there was no error code. The suggestion here has been that the Repository has been damaged somehow. I have therefore run a scan and repair from Supervisor. Almost every item on the list displayed stated "Invalid Last Action Datetime" - I must confess I am travelling very quickly towards those big words - YOU ARE OUT OF YOUR DEPTH!!! Can anybody provide any advice????
