// Get the ID of the attachment rather than the url, setting 3rd parameter
// to false will return unformatted value, intval is just in case a string 
// is returned
$file_id = intval(get_field('dokumente_datei', false false);

// get the thumbnail
$image = get_attachment_image_src($file_id, 'thumbnail');
