Remove duplicates not working.. Can't create relationship

[Anonymous]

Hello,

I have a dataset with customer and a discount structure for that customer per part. I created a concatenate in the edit query screen of the customer, and there are a couple duplicates. Highlighted the Concatenate column, and clicked remove duplicates.

Tried creating a relationship and it didn't work. Created a summary table of the concatenate and COUNTROWS, and lo and behold there are a handful that have a count of two. Why is this happening?

Thanks

I don't need to check duplicates, I need the query to filter them out properly so I can create a many-to-one relationship that doesn't return an error and mess up the scheduled refresh every time another duplicate is entered on the list.

The solution that has worked for me:

in the query editor, select your column that you want to be unique and then:

1) Click on the "Transform" tab in the ribbon, click on the "Format" button, and then select "UPPERCASE" or "lowercase"

2) make sure the column is still selected, then click on the "Home" Tab, and then click on the "Remove rows" button, then select "Remove Blank Rows"

3) make sure the column is still selected, then click on the "Home" Tab, and then click on the "Remove rows" button, then select "Remove Errors"

4) Finally, click on Remove Duplicates button.

So far, these steps have always worked for me!

What if it's a concatenated calculated column which you can't see in Power Query Editor?
