Some times it is good to have a direct link from response document to parent
document. For example, parent document is the costumer data and response
are contacts from costumer. When you read information of a contact you would
to read information of the costumer (click on link).
This way creates the link automatically in the response document.
In views be carefully to view response documents listed (don't select "Show
in a hierarchy")
In response document (in the example Contact form) create a Computed for
display text field (near to field that contains information about parent
document, in the example, the name of the costumer).
Assign the value $Ref to the field
Remember, the type of the forms have to be Document and Response respectively
