Problem:
Setup links to parent post, the link text is a custom field value of parent post.
I wrote a shortcode [next-post-id] to get the id of the next post.

function shortcode_next_post_id ($atts)
{
   global $post;
   $next_post = get_next_post();
   if (empty ($next_post))
        return 0;
   return $next_post->ID;
}
add_shortcode('next-post-id', 'shortcode_next_post_id');

Solution:
Since you have already got the post ID of next post with custom shortcode [next-post-id], so you can setup the link manually with HTML code, for example:

<a href="[wpv-post-url id=[next-post-id]]"> [types field='rs-brandname' id='[next-post-id]'][/types]</a>

Please make sure you have already registered the custom shortcode name in the Toolset setting page:
Dashboard->Toolset-> Front-end content
option "Third-party shortcode arguments", fill the custom shortcode name: next-post-id
