controller
class ControllerReportRemarketing extends Controller {
public function index()
{
$template="report/remarketing.tpl";
$this->load->language('report/remarketing');
$this->load->model('report/remarketing');
$this->template = ''.$template.'';
$this->data['record'] = 'test';
$this->children = array(
'common/header',
'common/footer'
);
$this->response->setOutput($this->render());
}
}

view
<?php echo $header; ?>
<div id="content">
<?php echo $record; ?>
</div>
<?php echo $footer; ?>
Also i've setting access permission to user in User Groups

I think you are using the old version opencart's code, here is the example for opencart version 2.0.2.0:
First, creat 'remarketing.php' under admin\language\english\report, add below content:
<?php
// Heading
$_['heading_title'] = 'Marketing Report';
Second, modify 'remarketing.php' under admin\controller\report as below
<?php
class ControllerReportRemarketing extends Controller{
public function index(){
// displayed text import
$this->load->language('report/remarketing');
// get header and footer
$data['breadcrumbs'] = array();
$data['breadcrumbs'][] = array(
'text' => $this->language->get('text_home'),
'href' => $this->url->link('common/dashboard', 'token=' . $this->session->data['token'], 'SSL')
);
$data['breadcrumbs'][] = array(
'text' => $this->language->get('heading_title'),
'href' => $this->url->link('extension/feed', 'token=' . $this->session->data['token'], 'SSL')
);
$data['heading_title'] = $this->language->get('heading_title');
$data['header'] = $this->load->controller('common/header');
$data['column_left'] = $this->load->controller('common/column_left');
$data['footer'] = $this->load->controller('common/footer');
// the model, need not to import
// $this->load->model('report/remarketing');
// testing
$data['record'] = 'test';
$this->response->setOutput($this->load->view("report/remarketing.tpl", $data));
}
}
?>
Last, modify 'remarketing.tpl' under admin\view\template\report
<?php echo $header; ?><?php echo $column_left; ?>
<div id="content">
<div class="page-header">
<div class="container-fluid">
<h1><?php echo $heading_title; ?></h1>
<ul class="breadcrumb">
<?php foreach ($breadcrumbs as $breadcrumb) { ?>
<li><?php echo $breadcrumb['text']; ?></li>
<?php } ?>
</ul>
</div>
</div>
<div class="container-fluid"><?php echo $record; ?></div>
</div>
<?php echo $footer; ?>
