Hello Satya,
Sorry I am not so familiar with SSIS..
Where can I set "Protection level for the Package"???
Thanks and Regards,

Check your package property called "ProtectionLevel". What is it set to?
And save the package to sql server with protection level setting to be relying on sql server roles.

Hi Satya,
I am able to change protection level of the package..
but i still got the ff error:
The product level is insufficient for component "Flat File Source

Looks like SSIS itself is not installed on machine. There are some components that will be installed only if you are installing SSIS in your installation.

Hi Satya,
Thanks for your help I am able to fixed my package error...
Thanks and Regards,
