Запуск Бизнес-процесса через API

Я запускаю БП таким образом, после добавления элемента в инфоблок.
 
   $orderID = $obElement->Add($arLoad);

   if (intval($orderID) > 0)
   {
      $arErrorsTmp = array();
      $wfID = CBPDocument::StartWorkflow(
                     $wfTemplateID,
                     array("iblock", "CIBlockDocument", $orderID),
                     array(
                        "ResponsibleUser" => "user_".intval($userID),
                        "ResponsibleUserID" => intval($userID),
                        "ResponsibleDept" => $sectionName,
                        "ResponsibleDeptID" => $dept,
                        "OrderDate" => date("d-m-Y"),
                        "OrderPrice" => $orderPrice
                        ),
                     $arErrorsTmp);
