The listing will have all of the Buyer Requirements indicated in this call.
If there are global MyeBay preferences set for BuyerRequirements, they will not be honored for this item.
This means that the AddItem call will override all of the MyeBay Buyer Requirements preferences.
There is no way to mix and match requirements that are globally set with requirements that are only in the AddItem call.
The AddItem call must indicate all of the requirements desired in the listing, even if they are already set in the global preferences.
Using the global MyeBay Buyer Requirements preferences
Listing with Buyer Requirements by using the global MyeBay Buyer Requirements preferences is done by not including the BuyerRequirements container in the AddItem request.
When no BuyerRequirements container is included in an AddItem request, all of the seller's global preferences with respect to Buyer Requirements are automatically picked up by the listing.
