I noticed there's a Duplicate Record/Request and a Copy Record/Request. What's the difference between these?
Copy will copy the contents of the fields into the clipboard. Duplicate will duplicate the record.
As for your orig question, you could create a script as such:
If [ not Is Empty ( Child::pkID ) ]
Go to Related Record [ Show only related; Child ]
Go to Record [ Last ]
Go to Layout [ Child ]
Go to Layout [ Parent ]
You probably can also do it using a self join and lookups for our field as well as another option.
Thanks mr_vodka, that works perfectly! :)
