QuickBooks API忽略TrackQtyOnHand字段？

I am trying to add an inventory item using the QuickBooks PHP SDK. I specify TrackQtyOnHand, the starting inventory and inventory start date, but these fields appear to be ignored?

Any help would be greatly appreciated!

thanks!

Here is the request:

    IPPItem Object

    [Name] => Product Name
    [Description] => ProductDesc
    [Active] => 1

    [UnitPrice] => 17.54386
    [RatePercent] => 
    [Type] => Inventory
    [PaymentMethodRef] => 
    [UOMSetRef] => 
    [IncomeAccountRef] => IPPReferenceType Object
        (
            [name] => Sales of Product Income
            [type] => Account
            [value] => 80
        )

    [PurchaseDesc] =>

        )

            [value] => 82
        )

    [PrefVendorRef] => 
    [AvgCost] => 
    [TrackQtyOnHand] => 1
    [QtyOnHand] => 10
    [QtyOnPurchaseOrder] => 
    [QtyOnSalesOrder] => 
    [ReorderPoint] => 
    [ManPartNum] =>

    [CustomField] => 
    [AttachableRef] => 
    [domain] => 
    [status] =>

Did you enable Track Quantity on Hand in your company setting->Sales tab?
