未能使用Amazon MWS Reports API获取财务交易报告

我使用亚马逊API已经2年多了，对它非常熟悉。我正在尝试使用Reports的API从亚马逊请求和订购此"_GET_DATE_RANGE_FINANCIAL_TRANSACTION_DATA_"报告，它正在为我生成ReportRequestID，但从未生成任何报告，我从过去3天开始请求。它的状态一直显示已提交，但从不更新为已完成状态。我也试过亚马逊ScratchPad。

我请求许多其他报告使用相同的报告的API，他们的工作非常完美。若有人遇到同样的问题，请告诉我。

这是我用来请求报告的代码：

     $sdate = new DateTime('-7 days', new DateTimeZone('UTC'));
     $startdate = $sdate->format("Y-m-d'T00:00:00P");
     $edate = new DateTime('-1 days', new DateTimeZone('UTC'));
     $enddate = $edate->format("Y-m-d'T23:59:59P");
     $AWS_ACCESS_KEY_ID = $pos['azn_access_key'];
     $AWS_SECRET_ACCESS_KEY = $pos['azn_secret_access_key'];
     $APPLICATION_NAME = $pos['azn_app_name'];
     $APPLICATION_VERSION = $pos['azn_app_version'];
     $MERCHANT_ID = $pos['azn_merchant_id'];
     $MARKETPLACE_ID = $pos['azn_marketplace_id'];
     $MERCHANT_TOKEN = $pos['azn_merchant_token'];
     $pos_name = $pos['nickname'];
     $pos_id = $pos['id'];
     $serviceURL = $pos['azn_service_url'];
     $config = array(
         'ServiceURL' => $serviceURL,
         'ProxyHost' => null,
         'ProxyPort' => -1,
         'MaxErrorRetry' => 3,
     );
     $service = new MarketplaceWebService_Client(
     $AWS_ACCESS_KEY_ID, $AWS_SECRET_ACCESS_KEY, $config, $APPLICATION_NAME, $APPLICATION_VERSION);
     $marketplaceIdArray = array("Id" => array($MARKETPLACE_ID));
     //Sends Report Request
     $parameters = array(
         'Merchant' => $MERCHANT_ID,
         'MarketplaceIdList' => $marketplaceIdArray,
         'ReportType' => '_GET_DATE_RANGE_FINANCIAL_TRANSACTION_DATA_',
         'ReportOptions' => 'ShowSalesChannel=true',
         'StartDate' => new DateTime($startdate, new DateTimeZone('UTC')),
         'EndDate' => new DateTime($enddate, new DateTimeZone('UTC')),
     );
     $request = new MarketplaceWebService_Model_RequestReportRequest($parameters);
     $request = new MarketplaceWebService_Model_RequestReportRequest();
     $request->setMarketplaceIdList($marketplaceIdArray);
     $request->setMerchant($MERCHANT_ID);
     $request->setReportType('_GET_DATE_RANGE_FINANCIAL_TRANSACTION_DATA_');
     $request->setReportOptions('ShowSalesChannel=true');
     $request->setStartDate(new DateTime($startdate, new DateTimeZone('UTC')));
     $request->setEndDate(new DateTime($enddate, new DateTimeZone('UTC')));
     $report_requestID = invokeRequestReport($service, $request);
