So I'm having this issue where when trying to handle items in suitescript, I have to load the item from the correct record type be that INVENTORY_ITEM/InvtPart, ASSEMBLY_ITEM/Assembly or NON_INVENTORY_ITEM.

So when I loop through my items, to be able to handle the possibility of multiple types of items I need to do first check the items type and then load it in the correct way.

On some records like an item receipt, this isn't too difficult because itemtype is a field in the item sublist. However, I am currently scripting an inventory adjustment that uses the sublist inventory which does not contain the itemtype field
