title: item fulfillment to invoice
body: <p>I'm trying to transform an item fulfillment to invoice. I created a custom field called "freight cost" and I"m trying to get the value of that field and transfer it over to the invoice and add two lines to the item sublist: "FREIGHT" and "HANDLING". However, I'm getting an error when I try to get the value of the freight cost.</p>
  
  <p>Here's my code:</p>
  
  <p>/**
   * @NApiVersion 2.x
   * @NScriptType UserEventScript
   * @NModuleScope SameAccount
   */
  define(['N/record', 'N/log'],</p>
  
  <p>function(record, log) {</p>
  
  <pre><code>function afterSubmit(context) {
      var orderId = context.newRecord;
      var freightCost = orderId.record.getValue({
          fieldId:'custbody_freight_cost'
      });
      log.error({
          title: 'Freight Cost',
          details: freightCost
      });
      var invoiceRecord = record.transform({
          fromType: record.Type.ITEM_FULFILLMENT,
          fromId: orderId,
          toType: record.Type.INVOICE,
          isDynamic: true
      });
      log.error({
          title: 'Debug Entry',
          details: invoiceRecord
      });
      var freightLine = invoiceRecord.insertLine({
          sublistId:'item',
          item: 3,
          ignoreRecalc: true
      });
      var handlingLine = invoiceRecord.insertLine({
          sublistId:'item',
          item: 4,
          ignoreRecalc: true
      });
      var freightSaver = invoiceRecord.setCurrentSublistValue({
          sublistId:'item',
          fieldId:'custbody_freight_cost',
          value: freightCost,
          ignoreFieldChange: true
      });
      var rid = invoiceRecord.save();
  }
  
  return {
      afterSubmit: afterSubmit
  };
  </code></pre>
  
  <p>}); </p>
  
  <p>And here's the error I'm getting:</p>
  
  <p>org.mozilla.javascript.EcmaError: TypeError: Cannot call method "getValue" of undefined (/SuiteScripts/complexInvoice.js#12)</p>
