How do I create an Intercompany Transfer Order via Suitescript?

Hi Everyone

First time poster here.  Thanks in advance for your assistance.

I am trying to create an Intercompany Transfer Order via suitelet and am unable to find out how to do so.  I realise that it is not located in the records browser (only Transfer Orders) but was trying to find a workaround to create it.

During my testing I attempted the following code:
  var rec = nlapiCreateRecord('transferorder');
  rec.setFieldValue('icto', 'T');
  rec.setFieldValue('subsidiary', 22);
  rec.setFieldValue('tosubsidiary', 24);
  rec.setFieldValue('location', 15);
  rec.setFieldValue('transferlocation', 16);
  rec.setFieldValue('orderstatus', 'B');
  rec.setFieldValue('firmed', 'T');
    rec.selectNewLineItem('item');
  rec.setCurrentLineItemValue('item', 'item', 1106);
