Thanks Surya.
The SQL version is 2012 and i am not certain on the client tools version. Since am using Information Steward via launchpad. Need to check with BASIS team as what version they have installed on the server system.
But the issue appears to be fixed. The BASIS team has restarted the Information Steward services and now am able to view the data in the tables.
Still I dont have an educated opinion for this issue. If you can give me some of the fixes to address this issue then that would be great.
