"Already exists" error when creating relationship

[Mackie]

There is a problem. I can't create a relationship between 2 tables.

Could you download the file above and try to create a relationship between 'Top10 Products of Sales 3-months' and 'Sales' by a column 'ProductKey'? That causes an error saying "Already exists". But I can not understand what causes that error. How can I solve? Thank you.

@Mackie ,

Hey try renaming the "ProductKey" field in the top 10 products table and then join them.

He's working alongside me.

Don't forget to thumbs up 👍 and accept this as a solution if it helped you.
