When I was working in configuration database. I think i unfortunately deleted Element "System Configuration" under PI Web API in Configuration database of PI AF, would any one know how to restore it back.

Hmm...it looks like if the <hostname> element still exists, then it won't make the System Configuration element underneath it.
Example. If this is your configuration (only the System Configuration element is missing, but the parent <hostname> element exists)
Then when you run the admin utility, it will see that the <hostname> element specified on the "Configuration Store" step exists, and it will skip that process.
The best way to recover would be to delete the <hostname> element entirely, then run the admin utility to get it all back in a good state.
You should be able to run the PI Web API Admin Utility again to create it. The admin utility was introduced in PI Web API 2015 R3. For previous versions, perform an uninstall/reinstall
