So I have two data frames. The first one is a reccomendation data frame and the second is a melted list with a pairing of OpportunityId's and ProductId's. There are multiple product id's per an opportunty id. What I want to do is merge based on ProductId so that I can add the OpportunityId to the reccomendation data frame.
