where to write a custom function and how to call the function?

This function can be called from anywhere during submission/ordering moment or approval moment or service delivery moment.

Any directly with examples will help as I am starting to learn SN tricks and way to do things.

Thanks,

Venky

Hello,

You can start checking "Script Includes" and "UI Scripts" to reuse JavaScript code in the Server and the Client.

Script Includes - ServiceNow Wiki

UI Scripts - ServiceNow Wiki

Or you could take one of the ServiceNow trainings available:
