      #"Added Conditional Column" = Table.AddColumn(Source, "New Collumn", each if [SecondColumn] = "Unkown" then "Sales" else [SecondColumn]),

I don't want to create a new column, I need to replace values.

    Hi vcb_001 

    As you stated that you want to replace the null based on another column, then you will need some logic to do this.

    You can add the logic to bring through the column you are using into the new column with the replaced values as well, then remove that column, so you are left with the one column and the values you need. 

    This is a simple transformation in PQ and will evaluete the table at source and push trhough the desired output to use in your model.
