         When you edit items from the Checkout screen, as opposed to editing 
          items from the Shopping Cart, additional information (such as accounting 
          and shipping information, and comments) is included. 
        If a non-catalog item's price is specified by a contract, you cannot 
          change the price. 
        If you are editing a line item from an order whose status is Shipping, 
          Shipped, Receiving, or Invoicing, you can change any field but: unit 
          price, unit of measure, item description, supplier, supplier location, 
          and supplier part number. Note that although you can change the quantity 
          and amount, they cannot be less than what has already been shipped or 
          received.  
         If orders are pushed to an ERP system, you cannot edit these fields 
          (in addition to those listed above):

        To change a non-editable field, delete the line item and then create 
          a new line item with the correct values.
