Relationships

 

 

I keep getting an error that tells me I cannot create a relationship between two tables because one of them has to have unique values.  Can someone explain this to me? Don't you need to join the tables together by a common point?

 

Thank you,

 

Joseph

A unique value is a column that does not contain any duplicates, thus unique. 

 

UNIQUE             NOT UNIQUE

1                         1

2                         1

3                         2

4                         3

One of the tables has to have unique values. If you cannot do that with your two tables, create a third table that pulls all of the values from both tables (merge step) and then does a "Unique values" step. Then, link both tables to that third table.

DAX is easy, CALCULATE makes DAX hard...

but what is considered a unique value? 

A unique value is a column that does not contain any duplicates, thus unique. 

 

UNIQUE             NOT UNIQUE

1                         1

2                         1

3                         2

4                         3

5                         1

 

That makes total sense.  Thank you!!!!
