     * copy_from_fields_to_propertys_values(22, array("DATE_ACTIVE_FROM","DATE_ACTIVE_TO"), array("DATE_BEGIN","DATE_END"));
     * */

        $arOrder = array(
            "sort" => "ASC",
        );

        $arFilter = array(
            "IBLOCK_ID" => $IBLOCK_ID,
        );

        foreach ( $TO_PROPERTY_NAMES as $property_name ) {
            $TO_PROPERTY_NAMES_with_prop[] = 'PROPERTY_' . $property_name;
