In reference to this ticket: https://toolset.com/forums/topic/cannot-filter-results-by-custom-field-from-child-relationship/

Is there a code example available to create fields in the desired CPT that retrieve/share the values from another CPT so they can be used be filtering for this example?

You would have to set up some Custom Code which for example updates fields in a Post of Type A when you save a Post of Type B.

Such code would get hooked at the save_post action of WordPress.
https://codex.wordpress.org/Plugin_API/Action_Reference/save_post

You would use get_post_meta() to get the Post Fields values from the saved post and then update_post_meta() to update the Fields in the other post:
https://developer.wordpress.org/reference/functions/get_post_meta/
https://developer.wordpress.org/reference/functions/update_post_meta/

This does not require Toolset to work, or Toolset's API to solve it, it's all based on PHP and WordPress, which is something we can not support here, therefore.

I can help you review the code if required, however, we cannot produce ready to use samples for these tasks as it does not require Toolset Features.
