Hi Vibhav,
- Is there any windows update that ran ?Did you reboot the server?
- Are you able to test 64 bit ODBC DSN successfully ? Check SQL Anywhere 12 driver as well.
- If yes then update data source in SIA properties again and now check if cms.exe is started from windows task manager.
- Open Windows Services and Make sure SQL Anywhere for SAP Business Intelligence' service is started .
Hope this will help you.
Regards,
Rukaiya
