Hi,
We have a custom multiple select field on all items.  I have a RESTlet  where users will be logged in with a Customer Center role.  The RESTlet code needs to get the values in the multiple select field on the item record.  I changed the custom item field to give View/Run access to the Customer Center role.  I have tried the following:

var recItem = nlapiLoadRecord('noninventoryitem', intItem);
>>> Code: INSUFFICIENT_PERMISSION Details: Permission Violation: You need the 'Lists -> Items' permission to access this page. Please contact your account administrator.

var intAdditionalContents = nlapiLookupField('noninventoryitem', intItem, 'custitem_addl_content');
