Combo Order - Item Description, Name and Note

While creating combo orders through the API, we have noticed that setting values for Description, Name, and Note in the Asi.Soa.Commerce.DataContracts.ItemSummaryData, Asi.Contracts (Item Object) does not result in the set value being stored in iMIS Enterprise. However, if an item is ordered through the iMIS interface and and a note is added, the note is properly stored. It appears that the SET property is not function as needed. For the Name and Description, it appears that a lookup from the Product table is what is being used instead of what is being sent through the API.
