We started using the Enable Item Line Shipping checkbox on sales order over the past year. It has been a tremendous improvement for our sales teams since they can now place an order on the fly with multiple shipping methods or ship to addresses. However, these multi-ship orders have caused a problem when billing.

We bill from the Item Fulfillment so we only want to invoice the customer what has actually been shipped out; the item(s) and actual shipping cost for that item. When we bill sales orders that use item line shipping, it will bill the item(s) that have been shipped and the actual shipping cost, but it also bills the remaining shipping cost as calculated from the sales order. This is not how we want or expect it to function.
