Formula To Create A Static URL of a record that will copy intact to a new copied record.

Note that with the solution above. If you copy a copied record, the static URL will refer to the very original record.

But that is actually good. You can make a report link field based on that static URL and show that on every ticket. Then automatically you will have a history of all the previous tickets that are related to that original ticket.

It is actually a pretty cool and easy technique. Thank you for making me think of it.
