Hello, I'm trying to add inventory items through NS web services. I'm able to add a standard inventory item with no issue. However, when I add a drop ship item, I get the following message: Drop ship/Special order items must have a preferred vendor and purchase price. Now the purchase price is NBD, standard field with a corresponding provided flag. However, I'm having a hard time tracking down a C# example of setting the preferred vendor through the ItemVendorList. Is anybody familiar with this? Could you please point me in the right direction?

general strategy should be to get an existing item with a preferred vendor and copy the fields you are interested in
