Relationship and Unique Values

‎04-24-2018 11:36 AM

Hi there,

 

I have a 2 files with many entries trying to relate them together via email addresses. When I try relating the 2 together, I get an error "You can't create a relationship between these two columns because one of the columns must have unique values".  1 file has over 40,000 rows and the other has about 7000.

 

So far I've done: Removed errors, trimmed text, removed blanks, removed nulls, lowercased cells, tried both CSV and XLSX file formats, and created a new query with all of the emails to make it a middle of the relationship.

 

 I've been stuck with this issue for 2 days now and can't figure out what I'm doing wrong.

Hi @klammymaster

 

Here is a DAX Soluction for creating a slicer table that will have unique values that you can create relationships too.

 

Then use the field in this table for your slicers

 

Slicer Table = 
    DISTINCT(
        UNION (
            ALL('biibuserdata'[biibEmail]) ,
            ALL(Intune[Email address])
            )
            )
