Customizing NetSuite Forms with SuiteScript:

One of the most common use cases for SuiteScript is customizing NetSuite forms to improve user experience and streamline data entry. SuiteScript enables you to add custom fields, change labels, or even hide fields based on specific conditions. To achieve this, you can leverage the SuiteScript 2.0 API, which provides a rich set of objects and methods to manipulate forms.

Example: Automatically populating a custom field based on other field values

/**
 * @NApiVersion 2.x
 * @NScriptType ClientScript
 */
define(['N/currentRecord'], function(currentRecord) {

	function fieldChanged(context) {

		var record = context.currentRecord;

		var fieldName = context.fieldId;


		if (fieldName === 'custbody_source_field') {

			var sourceFieldValue = record.getValue(fieldName);

			var targetField = 'custbody_target_field';


			// Your custom logic for deriving the target field value

			var targetFieldValue = calculateTargetFieldValue(sourceFieldValue);


			record.setValue(targetField, targetFieldValue);

		}
	}


	return {

		fieldChanged: fieldChanged

	};
});

Automating Business Processes with SuiteScript:

SuiteScript enables you to automate various business processes, from simple tasks like sending email notifications to complex workflows spanning multiple records and approvals. The Scheduled Script and Suitelet script types are particularly well-suited for automation.

Example: Implementing a Scheduled Script to automate batch processing

/**
 * @NApiVersion 2.x
 * @NScriptType ScheduledScript
 */
define(['N/search', 'N/record', 'N/log'], function(search, record, log) {
   
function execute(context) {
       
var mySearch = search.create({
           
type: search.Type.CUSTOMER,
           
columns: ['internalid', 'firstname', 'lastname'],
           
filters: [['custentity_needs_processing', 'is', 'T']]
       
});

       
var searchResults = mySearch.run().getRange({ start: 0, end: 1000 });

       
for (var i = 0; i < searchResults.length; i++) {
           
var customerId = searchResults[i].getValue('internalid');
           
// Your custom logic for processing each customer record
           
processCustomer(customerId);
           
log.debug('Processed Customer', customerId);
       
}
    }

    return {
       
execute: execute
   
};
});

Extending NetSuite Functionality with Suitelets:

Suitelets are server-side scripts that run on-demand, enabling you to create custom web pages, RESTful APIs, and other extensions to NetSuite. They are an excellent way to address specific business requirements that cannot be met by native NetSuite functionality.

Example: Creating a custom Suitelet page for data entry

/**

 */
define(['N/ui/serverWidget'], function(serverWidget) {
   
function onRequest(context) {
       
if (context.request.method === 'GET') {
          
 var form = serverWidget.createForm({
                title: 'Custom Data Entry'
          
 });

       
form.addField({
           
id: 'custpage_field1',
           
type: serverWidget.FieldType.TEXT,
            label: 'Field 1'
       
});

       
form.addField({
           
id: 'custpage_field2',
           
type: serverWidget.FieldType.TEXT,
           
label: 'Field 2'
       
});

       
form.addSubmitButton({
           
label: 'Submit'
       
});

       
context.response.writePage(form);
    } else {
       
var field1Value = context.request.parameters.custpage_field1;
       
var field2Value = context.request.parameters.custpage_field2;

       
// Your custom logic for processing the submitted data
       
processData(field1Value, field2Value);

       
context.response.write('Data successfully submitted!');
    }
}

return {
   
onRequest: onRequest
};
});

Debugging and Troubleshooting SuiteScript:

As you develop and implement SuiteScript customizations, you will inevitably encounter challenges that require debugging and troubleshooting. NetSuite provides tools to help you identify and resolve issues, such as script logs, the SuiteScript Debugger, and the Execution Log.

Saved Search Example:

var search = require('N/search');
var runtime = require('N/runtime');

function executeSavedSearch() {
    var start = new Date().getTime();

    var salesOrderSearch = search.create({
        type: search.Type.SALES_ORDER,
        filters: [
            ['amount', 'greaterthan', 1000]
        ],
        columns: [
            search.createColumn({ name: 'entity', summary: 'GROUP' }),
            search.createColumn({ name: 'internalid', summary: 'GROUP' }),
            search.createColumn({ name: 'amount', summary: 'SUM' })
        ]
    });

    var searchResults = [];
    salesOrderSearch.run().each(function (result) {
        searchResults.push(result);
        return true;
    });

    var end = new Date().getTime();
    var duration = end - start;
    log.debug('Saved Search Execution Time:', duration + 'ms');

    return searchResults;
}

SuiteQL Example:

var query = require('N/query');
var runtime = require('N/runtime');

function executeSuiteQL() {
    var start = new Date().getTime();

    var suiteQL = 'SELECT T.entity, T.internalid, SUM(T.amount) as total_amount ' +
                  'FROM Transaction T ' +
                  'WHERE T.type = \'SalesOrd\' AND T.amount > 1000 ' +
                  'GROUP BY T.entity, T.internalid';

    var suiteQLResult = query.runSuiteQL({ query: suiteQL });
    var results = suiteQLResult.asMappedResults();

    var end = new Date().getTime();
    var duration = end - start;
    log.debug('SuiteQL Execution Time:', duration + 'ms');

    return results;
}

        inputEncoding: encode.Encoding.UTF_8,
        outputEncoding: encode.Encoding.HTML
    });

    // Validate the sanitized input (e.g., check length, allowed characters)
    if (sanitizedSearchTerm.length > 100 || !/^[a-zA-Z0-9\s]+$/.test(sanitizedSearchTerm)) {
        throw new Error('Invalid search term.');
    }

    // Use the sanitized and validated input in a search
    var itemSearch = search.create({
        type: search.Type.ITEM,
        filters: [['name', 'contains', sanitizedSearchTerm]]
    });

    var resultSet = itemSearch.run();
