Challenge:
Display a lookup in a related list. For example, when viewing a Contact record, we wanted to see the Campaign an Opportunity is associated with. Unfortunately, this is not possible using the standard interface.
My Solution:
Create a formula field that populates/references the lookup field (Campaign) and then add that field to the related list (no need to have it in your page layout).
Voila!
Now you can go into the weekend with ease of mind.
