PHP SOAP Client, ошибка не такая операция

У меня проблема с моим клиентом SOAP на PHP, я думаю, что мой запрос правильный.

Мой PHP-клиент SOAP:

$soapURL = "http://mylink.fr/mywsdl?wsdl";
$soapParameters = Array('login' => "MyLogin", 'password' => "MyPassword", 'trace' => 1);
try {

$service=new SoapClient($soapURL, $soapParameters);

$request = array(
'address' => array(
'city' => '',
'country' => '',
'department' => '',
'district' => '',
'houseNumber' => '',
'region' => '',
'road' => '',
'roadNumber' => '',
'zipCode' => ''
),
'category' => array(
'logo' => '',
'name' => '',
'reference' => ''
),
'companyName' => '',
'contactMail' => '',
'contactName' => '',
'contactPhone' => '',
'endTemporary' => '2015-02-15T13:00:10',
'latitude' => 12.0,
'longitude' => 12.0,
'name' => '',
'radius' => 520,
'reference' => '',
'startTemporary' => '2015-02-15T13:00:11',
'temporary' => 0
);

$result = $service->createPOI($request);
} catch(SoapFault $e) {

echo $service->__getLastRequest();
echo $e->__toString();

}

Мой SOAP-запрос:

Я получаю эту ошибку:

SoapFault exception: [Server.userException] No such operation 'createPOI' in /var/www/devt/cronJobs/test.php:58
Stack trace: #0 /var/www/devt/cronJobs/test.php(58): SoapClient->__call('createPOI', Array)
#1 /var/www/devt/cronJobs/test.php(58): SoapClient->createPOI(Array)
#2 {main}

Можете ли вы сказать мне, где моя проблема и объяснить мне?

Я новичок с SOAP

заранее спасибо
