Dim Shows Cardinality As Many After Remove Duplicates

Hi all,

 

Using PBI Desktop.
I imported a sheet from an Excel Workbook.

I cleaned everything up including deleting duplicates on Group id to create a dim table.

 

I tried to join to a fact table, but I receive a warning about M:M relationship.

 

How is that possible if I removed duplicates?

 

I deleted the table and repeated the entire process, same response.
What can I do to get the dim table correct so I have 1:M relationship to the fact table?

 

Thanks,

  • If there are definately no duplicate keys in your join - are there any blank records that may be causing the link to turn into a M:M

  • Thanks Dean,

    I added a Matrix and added the id to the Matrix.
    The Null floated to the top.

    I cannot see the null in the id field in PQ Editor: "Limit of 1000 rows reached"
    I aaded a column to check the length of the item in the id field and received either 6 or null.

    I filtered out the null.
    Close/apply.

    Now I am able to connect dim to fact.
