Incorrect error message when managing relationships

[jessicachen]

The error code says "you can’t create a relationship between these two columns because one of the columns must have unique values" even when I have a column that has unique values.

Hi @jessicachen,

Please go to Data tab, find the column which you mentioned contains distinct values. You will see numbers of rows and how many distinct values in this column. Please check if this two values are the same.
