[Resolved] Filter view to show posts that do not have any child relationship

Tell us what you are trying to do?
I have a Post Type "Report" and then three child post types "Cause", "Action" and "Conclusion" which act as notes for the report.

What I need to be able to do is create a view that filters the reports to show me a list of those that do not have any notes attached (so that they can be followed up)

Is there any documentation that you are following?

https://toolset.com/forums/topic/conditional-output-based-on-post-relationships/ - I looked at this but it does not seem to work in my case (always returns zero) and of course I'm not sure how to use it as a filter.

So, I've created the following views - you can see how I configured both the views.
=> hidden link
=> hidden link

The parent view is configured as given under:
=> => hidden link

[wpv-layout-start]
	[wpv-items-found]
	<!-- wpv-loop-start -->
		<wpv-loop>
     
          [wpv-view name="child-resources" ptitle="[wpv-post-title]"]
		</wpv-loop>
	<!-- wpv-loop-end -->
	[/wpv-items-found]
	[wpv-no-items-found]
		<strong>[wpml-string context="wpv-views"]No items found[/wpml-string]</strong>
	[/wpv-no-items-found]
[wpv-layout-end]

The child-view with the post relationship filter is configured as given under:
=> hidden link

[wpv-layout-start]
	[wpv-items-found]
	<!-- wpv-loop-start -->
		<wpv-loop>
		</wpv-loop>
	<!-- wpv-loop-end -->
	[/wpv-items-found]
	[wpv-no-items-found]
      <li> [wpv-attribute name="ptitle"]</li>	
	[/wpv-no-items-found]
[wpv-layout-end]

Where - as you can see we are cathing the "ptitle" value using the shortcode [wpv-attribute] that we passed from the parent view's loop [wpv-view name="child-resources" ptitle="[wpv-post-title]"].

Then, I've this following test page:
=> hidden link

I can see its working fine. Can you please confirm

Also, I forget to update you that from Toolset => Relationship I've migrated the site to new relationship:

Thank you - I have changed it a little to work with multiple relationships and it seems to working great - now I just need to display other data within the loop
