Amazon MWS is reporting incorrect inventory Quantities

[csaunders]

It should be reporting the available quantity not the total quantity, which includes things that haven't been received by the fulfillment centre yet.

<ListInventorySupplyResponse xmlns="http://mws.amazonaws.com/FulfillmentInventory/2010-10-01/">
  <ListInventorySupplyResult>
    <InventorySupplyList>
      <member>
        <SellerSKU>superawesomefancything</SellerSKU>
        <ASIN>A000000000</ASIN>
        <TotalSupplyQuantity>15</TotalSupplyQuantity>
        <FNSKU>X123456789</FNSKU>
        <Condition>NewItem</Condition>
        <InStockSupplyQuantity>0</InStockSupplyQuantity>
        <SupplyDetail/>
        <EarliestAvailability>
          <TimepointType>Unknown</TimepointType>
        </EarliestAvailability>
      </member>
    </InventorySupplyList>
  </ListInventorySupplyResult>
  <ResponseMetadata>
    <RequestId>adadada-adadadada-adadadada-adadada</RequestId>
  </ResponseMetadata>
</ListInventorySupplyResponse>

In this example it should be reporting the inventory for superawesomefancything to be 0 instead of 15
