Record type/field ids not showing on autocomplete in SuiteCloud IDE

There are instances that some of the fields/record types does not appear in the list of autocomplete suggestions using SuiteScript API such as nlapiSearchRecord or nlapiLoadRecord this is because fields/record types is not included in the SuiteScript Record Browser.
 

Sample scenario below:

* Load a sales order record and get the value of Shipping Carrier using getFieldValue method

var rec = nlapiLoadRecord('salesorder',1234)

"shipcarrier" is not on the list of autocomplete

* If you check the SuiteScript Record Browser , this field is included in the line item but not as body field which is the possible reason why it is not showing on the autocomplete.

rec.setLineItemValue('item','shipcarrier')
