Amazon MWS履行提要-处理“一个或多个项目无效”后的错误响应

Question

i submit a fulfillment feed and always get the same error (after requesting GetFeedSubmissionResult), my acknowledgement feed works and i can see the updated MerchantOrderId in Sellercentral.

The feed xml is:

<?xml version="1.0" encoding="UTF-8"?>
<AmazonEnvelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="amzn-envelope.xsd">

       <FulfillmentDate>2015-12-23T09:03:18+0100</FulfillmentDate>
       <FulfillmentData>
           <CarrierCode>DHL</CarrierCode>
           <ShipperTrackingNumber>1667***</ShipperTrackingNumber>
       </FulfillmentData>
    <Item>

        <Quantity>1</Quantity>
    </Item>
    </OrderFulfillment>
</Message>
</AmazonEnvelope>

</Message>
</AmazonEnvelope>

I tried with and without the <Item></Item> Part, i tried without <MerchantFulfillmentID> , i tried <MerchantOrderId> instead of <AmazonOrderId> ... I also tried <ShippingMethod>Standard</ShippingMethod> but i dont know if "Standard" is a valid value.

So can anyone point me in the right direction - what am i missing here? Is there any neccessary action before the fulfillment feed that i might have missed? Is the <MerchantFulfillmentID> just a value i can choose here or does it have to be set in some feed before?

Thanks!

Ok i figured it out - the Date Format seems to be the problem.

In the documentation i only find "ISO8601" but in PHP DateTime::ISO8601 will give a string like 2015-12-23T09:03:18+0100 while amazon seems only to accept +01:00 instead of +0100 . In PHP this is DateTime::ATOM and not ISO8601 .

So in PHP Code you should use $date->format(DateTime::ATOM) in the feeds.
