Is it possible to add a phone field to the Opportunity Page Layout?
Screenshot of me trying. No phone fields available - http://screencast.com/t/Uj4lgBEWTcS
I don't think that it is possible. I was asked to add it, so I want to make sure that I can't before I tell the client this. I have looked in the Salesforce forums, and googled extensively.
According to my understanding, only contacts and leads can have a phone number. Of course we can relate a contact to the opportunity but AFAIK, it is not possible to add a phone number directly to the opportunity object. Is this correct?
