Example: Creating a Simple User Event Script

Let's walk through a basic example to illustrate the process. Imagine you want to automatically set the 'Sales Rep' field on a new sales order to the current user. Here's how you might do it with a User Event script:

/**
 * @NApiVersion 2.x
 * @NScriptType UserEventScript
 */

define(['N/record', 'N/runtime'],
    function(record, runtime) {
        function beforeSubmit(context) {
            if (context.type === context.UserEventType.CREATE) {
                var newRecord = context.newRecord;
                var userId = runtime.getCurrentUser().id;
                newRecord.setValue({ fieldId: 'salesrep', value: userId });
            }
        }
        return {
            beforeSubmit: beforeSubmit
        };
    });

This script uses the beforeSubmit event to modify the sales order before it's saved to the database. It checks if the record is being created, gets the current user's ID, and sets the 'salesrep' field accordingly. This is a super simple example, but it showcases the basic structure of a SuiteScript and how it interacts with NetSuite records. Remember to adapt this script to your specific needs, ensuring that the field IDs and logic align with your NetSuite configuration. Thorough testing in a sandbox environment is essential before deploying any script to a production environment. Proper error handling and logging should also be implemented to facilitate troubleshooting and ensure the script's reliability. With practice, you'll be able to create more complex and sophisticated scripts to automate your business processes and enhance your NetSuite experience.
