After googling for one hour I couldn't find any answer to this question. Sorry if this duplicated but I couldn't find it.
I've created a custom object that I want to add opportunities to the related list.
So I created a lookup relationship linked to opportunity, but I can't add it to the list.
How could I add a new field to related lists? How could I add my lookup relationship to the related lists?
I can see the object as amplified lookup, but not in the related list.
