Update Purchase Order Item

This request updates a Purchase Order Item. Considering the validation for this route is non-trivial -- keep in mind that before this update takes place, we validate the resulting PO Item, so the itemType must be valid with any existing or updated properties. For example, if you have a PO Item of itemType 1 (Part) and attempt to send a PATCH that only provides a checklistID, you will get an error back saying that this is an invalid combination.

To remove an associated ID, pass in the value 0.
