i want solution if the user enter discount rate more than 20% on total invoice amount he can not save the invoice until he edit the rat to less than 20%

AI generated answer (using internal Slack threads):

Based on the conversations, it seems like you want to prevent a user from saving an invoice if they enter a discount rate of more than 20% on the total invoice amount. This can be achieved by using a User Event (UE) script in NetSuite's SuiteScript. Here's a high-level overview of how you can implement this: 1. Create a User Event script that triggers on the 'beforeSubmit' event of the Invoice record. 2. In the script, retrieve the discount rate entered by the user. 3. If the discount rate is more than 20%, throw an error and prevent the record from being saved. Here's a basic example of how the script might look:

javascript
/**
 * @NApiVersion 2.x
 * @NScriptType UserEventScript
 * @NModuleScope SameAccount
 */
define(['N/record', 'N/runtime'], function(record, runtime) {
    function beforeSubmit(context) {
        if (context.type !== context.UserEventType.CREATE && context.type !== context.UserEventType.EDIT)
            return;

        var newRecord = context.newRecord;
        var discountRate = newRecord.getValue({
            fieldId: 'discountitem' // replace with your discount rate field id
        });

        if (discountRate > 20) {
            throw {
                name: 'DISCOUNT_RATE_EXCEEDED',
                message: 'Discount rate cannot be more than 20%. Please edit the rate to be less than or equal to 20%.'
            };
        }
    }

    return {
        beforeSubmit: beforeSubmit
    };
});

Please replace

'discountitem'

with the actual field id of your discount rate field. Remember to deploy the script and associate it with the Invoice record type. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
