Hi Arun,
Looking at the error message it appears that you are using CRforE.
This because you do not have a 64 bit DSN
Go to the following location on your BO server box:
C:\Windows\SysWOW64 folder on the 64bit Windows platform.
Run odbcad32.exe and create a DSN with same name using same drivers on your server box
Now try to create a report
