php 与 sap 接口通信问题

Question

公司项目需要与sap(abap)接口通信，我这边是php，对方是sap。new SoapClient()时就报错。现在把对方wsdl文件拿到本地做（线上是有用户密码）$wsdl = "http://www.svnmms.com/DOC_WEBI_YLL_RFC02.WSDL";
try{
$client = new SoapClient($wsdl,array('soap_version'   => SOAP_1_2));
}catch(Exception $e){
  //echo 'Message:'.$e->getMessage();
        echo $e->__toString();
   }var_dump($client->__getFunctions());
?>
执行后报错：
SOAP-ERROR: Parsing WSDL: Unknown required WSDL extension 'http://schemas.xmlsoap.org/ws/2004/09/policy'查百度
<wsp:UsingPolicy wsdl:required="true"/> 说是要把true改为false 我改后又报这错
SOAP-ERROR: Parsing WSDL: Couldn't bind to service小弟现在把sap给我的wsdl文件也上传上来，麻烦大家帮我看看，问题出在哪里，如何解决问题。WSDL内容：

后来我改用SoapParam这个。还是有报错。SoapFault exception: [VersionMismatch] Wrong Version$wsdl = "http://XXXXXXX/sap/bc/srt/wsdl/flv_10002A111AD1/bndg_url/sap/bc/srt/rfc/sap/yll_rfc02/300/yll_rfc02/yll_rfc021?sap-client=300?wsdl";
$client = new SoapClient(null,array(
'location'=>$wsdl,
'uri'=>"XXXXXXX",
'login' => 'IF_ALL',
'password' => '123456', 'soap_version' => SOAP_1_2,
'style'    => SOAP_DOCUMENT,
            'use'      => SOAP_LITERAL,
'cache_wsdl' => WSDL_CACHE_NONE, 
'features' => SOAP_SINGLE_ELEMENT_ARRAYS, 
'exceptions'=>true,
 "stream_context" => stream_context_create(
                array(
                    'ssl' => array(
                        'verify_peer' => false,
                        'verify_peer_name' => false,
                    )
                )
            ),
'https' => array(
'curl_verify_ssl_peer'  => false,
'curl_verify_ssl_host'  => false
)
));
$str =  $client->YllRfc02(new SoapParam('123', 'IMatnr'));
var_dump($str);
} catch (Exception $e) {                           
        printf("Error:sendSms: %s\n",$e->__toString());
        return false;      echo 'Message:'.$e->getMessage();

http://172.16.9.30:8000/sap/bc/srt/wsdl/flv_10002A111AD1/bndg_url/sap/bc/srt/rfc/sap/yll_rfc01/300/yll01/yll011?sap-client=300
不知道外网能不能打开。我在公司是挂VPN访问 的。不过还有个sapsrv01.zhongwang.com:8000 您看看能不能访问
