Copy data from a selected view in a fieldcollection field
Yes, it's possible but you're going to have to do some hoop jumping to make it happen:


Determine when this copy action will happen (e.g. hook_entity_update trigger).
Programmatically retrieve the View's data (e.g. via Views::getView() /  views_get_view() depending on your Drupal version)
Parse the view data an update the update relevant node fields with the view data. (which will also depend on your Drupal version).
