It looks like you have done this a number of times before, but perhaps someone else worked on the site for you.
Here's where in View 20072 you inserted View 20133 previously:
[wpv-view name="view-to-show-participation-of-a-person-in-the-results-on-a-single-dogs-results"
wpvrelatedto="[wpv-post-id item='@dog-dog-appearance.parent']"
role="Owner"
]
I've formatted it across a few lines so that you can see how it is put together more easily.
You call the View (by name) and then you pass two shortcode attributes to the called View, the first being "wpvrelatedto" which passes the ID of the parent dog post, and the second being "role", where you have passed a string "Owner".
Then in the second View you use these passed values in two Query Filters (screenshot).
What I described above (https://toolset.com/forums/topic/limiting-the-data-shown/#post-1548445) involves doing more of the same. Here's the documentation for reference: https://toolset.com/documentation/user-guides/views/passing-arguments-to-views/
Now, this is what you added where you insert the second View:
[wpv-view name="view-to-show-participation-of-a-person-in-the-results-on-a-single-dogs-results"
wpvrelatedto="[wpv-post-id item='@dog-dog-appearance.parent']"
role="Owner"
]
[wpv-post-id item="@event-dog-appearance.parent"]
You haven't added an attribute to the call to the View, you are outputting the parent event ID after the shortcode that inserts the View.
You are nearly there, but that wpv-post-id shortcode needs to be providing the value for a shortcode attribute that will then be used by a Query Filter in the target View.
You have already added such a relationship Query Filter to that View: Select posts in a Events Person Appearances relationship that are related to the Post with ID set by the shortcode attribute wpvrelatedto.
You have a problem in that you are already using the 'wpvrelatedto' attribute to pass the dog ID, so you'll need to change the name of one of them because they need to be unique.
It doesn't matter what you use for the attribute name, what does matter is that the name you use in the wpv-view shortcode is the same as the name specified in the corresponding Query Filter.
So maybe edit the Query Filter and change the attribute name to something like 'event', and then update where you insert the View (as shown in the code block above) so that your wpv-post-id shortcode is providing the value for that shortcode attribute. (Be careful about mixing single and double-quotes, check how it is for the existing wpvrelatedto attribute.)
