Relationship Difficulty - Message with multiple values Found

Dears

 

I am creating a PowerBI file with a few tables directly connected with our system.

 

Basically I have Commercial Budget (many) and Item Master (one).  Both are linked by using the item code.

 

The point is that Master Item has a column named "Family", the purpose of this field is to create a simpler clasification to analyze sales (instead of multiples codes, we wrap them in families for better analysis).

I have created a query with that column, covert to Table, arrange, rename and remove duplicates

 

The "funny" thing is when I try to create a relathionship between the new query "Family" with Commercial Budget, a message telling me is not possible because no "uniques values in any table" appers.

 

How is this possible? Why can't PowerBI recognize the new Query "Family" as single values after removing duplicates?

I could use related but I want a different design...

 

I hope you may help :-)

 

Regards,

    Just checking my MasterFile, I found out we have some items without Family assigned (they appear blank)

     

    ¿Could this be the reason?:smileyembarrassed:

      Hi Ciria,

       

      >>Just checking my MasterFile, I found out we have some items without Family assigned (they appear blank)

      Yes, multiple blank value will cause the issue.

       

      In my opinion, you can remove these blank value at power query or create a new table with distinct column value and add the relationship between new table and original tables.

        Hi Anonymous

         

        I have created this new column:

         

        Column = CALCULATETABLE(DISTINCT(vSP_ArticulosAll[Family]))

         

        The following message is returned: A table with multiple values was supplied where a single value was expected.

         

        Awaiting for your support.
