write me a user event suite script for when a return transaction is created, make sure each line item has the inventory detail filled out, if not add a default issueinventorynumber of "v_0.0" and the needed quanity.

AI generated answer (using internal Slack threads):

Based on the conversations, here is a sample User Event SuiteScript that you can use to ensure each line item has the inventory detail filled out when a return transaction is created. If not, it adds a default issueinventorynumber of "v_0.0" and the needed quantity. Please note that this is a simplified example and may need to be adjusted to fit your specific needs.

javascript
/**
 * @NApiVersion 2.x
 * @NScriptType UserEventScript
 * @NModuleScope SameAccount
 */
define(['N/record', 'N/search'], function(record, search) {
    function beforeSubmit(context) {
        if (context.type !== context.UserEventType.CREATE) return;
        var newRecord = context.newRecord;
        var numLines = newRecord.getLineCount({ sublistId: 'item' });
        for (var i = 0; i < numLines; i++) {
            var inventoryDetail = newRecord.getSublistSubrecord({
                sublistId: 'item',
                fieldId: 'inventorydetail',
                line: i
            });
            if (!inventoryDetail) {
                var issueInventoryNumber = 'v_0.0';
                var quantity = newRecord.getSublistValue({
                    sublistId: 'item',
                    fieldId: 'quantity',
                    line: i
                });
                inventoryDetail = record.create({ type: 'inventorydetail', isDynamic: true });
                inventoryDetail.selectNewLine({ sublistId: 'inventoryassignment' });
                inventoryDetail.setCurrentSublistValue({
                    sublistId: 'inventoryassignment',
                    fieldId: 'issueinventorynumber',
                    value: issueInventoryNumber
                });
                inventoryDetail.setCurrentSublistValue({
                    sublistId: 'inventoryassignment',
                    fieldId: 'quantity',
                    value: quantity
                });
                inventoryDetail.commitLine({ sublistId: 'inventoryassignment' });
                newRecord.setSublistSubrecord({
                    sublistId: 'item',
                    fieldId: 'inventorydetail',
                    line: i,
                    value: inventoryDetail
                });
            }
        }
    }
    return {
        beforeSubmit: beforeSubmit
    };
});
