How to Access Item Type and Subtype on NetSuite Transaction Line Items

The items list on NetSuite transaction entities, such as Sales Orders and Purchase Orders, contains hidden fields that provide access to an item's type and subtype. This information is valuable for implementing specific validations or logic based on item classification.

Common item type and subtype values include:

TYPE_NON_INVENTORY 'NonInvtPart'

TYPE_SERVICE 'Service'

TYPE_OTHERCHARGE 'OthCharge'

TYPE_KIT 'Kit'

TYPE_DESCRIPTION 'Description'

TYPE_ASSEMBLY 'Assembly'

SUB_TYPE_SALE 'Sale'

SUB_TYPE_PURCHASE 'Purchase'

SUB_TYPE_RESALE 'Resale'

Subtypes are applicable for Non-Inventory, Service, and Other Charge item types.

To programmatically access these values, NetSuite recommends using SuiteScript 2.1. The equivalent methods for retrieving item type and subtype from transaction line items are record.getCurrentSublistValue for the currently selected line and record.getSublistValue for a specific line number.

Example using record.getCurrentSublistValue (e.g., in a client script):

javascript
/**
 * @NApiVersion 2.1
 * @NModuleScope SameAccount
 */
define(['N/record'], function(record) {
    function pageInit(context) {
        var currentRecord = context.currentRecord;
        var itemType = currentRecord.getCurrentSublistValue({
            sublistId: 'item',
            fieldId: 'itemtype'
        });
        var itemSubType = currentRecord.getCurrentSublistValue({
            sublistId: 'item',
            fieldId: 'itemsubtype'
        });
        // Example: console.log('Current Item Type:', itemType, 'Subtype:', itemSubType);
    }
    return {
        pageInit: pageInit
    };
});

Example using record.getSublistValue (e.g., in a user event script or for a loaded record):

javascript
/**
 * @NApiVersion 2.1
 * @NModuleScope SameAccount
 */
define(['N/record'], function(record) {
    function afterSubmit(context) {
        var newRecord = context.newRecord;
        var lineCount = newRecord.getLineCount({ sublistId: 'item' });
        for (var i = 0; i < lineCount; i++) {
            var itemType = newRecord.getSublistValue({
                sublistId: 'item',
                fieldId: 'itemtype',
                line: i
            });
            var itemSubType = newRecord.getSublistValue({
                sublistId: 'item',
                fieldId: 'itemsubtype',
                line: i
            });
            // Example: console.log('Line', i, 'Item Type:', itemType, 'Subtype:', itemSubType);
        }
    }
    return {
        afterSubmit: afterSubmit
    };
});
