Both Column Values Match including a blank one

[awsiya]

Hello all,

I am encountering an issue when using DAX to perform the following calculation. I have a simple table containing only two columns, "Sorted" and "Preferred." The task at hand is to determine the count of values in the "Sorted" column that match exactly those in the "Preferred" column. Additionally, if a value in the "Sorted" column corresponds to a BLANK cell in the "Preferred" column, it should also be considered a match. However, when both cells are either "blank or Null," they should not be counted. In the given example, the DAX calculation should yield "4" for the variable "SortedMatchesPreferred," with the breakdown as follows:

The row with '2A' matches '2A'.
The last row with '3' matches '3'.
The fourth row with '5' has a BLANK value in the corresponding row (which should be counted as a match).
The seventh row with '4' has a BLANK value in the corresponding row (which should also be counted as a match).

@awsiya change the measure to this:

Sorted Matched Preferred Measure = 
COUNTROWS ( 
   FILTER ( 
      Table, 
      COALESCE ( Table[Preferred], Table[Sorted] ) = Table[Sorted] && 
      NOT ISBLANK ( Table[Sorted] ) 
   )
)

Thank you, it worked 🙂

@awsiya if you don't want to add a column you can also a measure directly:

Sorted Matched Preferred Measure = 
COUNTROWS ( FILTER ( Table, COALESCE ( Table[Preferred], Table[Sorted] ) = Table[Sorted] ) )

Hi @awsiya ,

How about this:

Here the DAX Measure:

Measure = 
CALCULATE (
    COUNTROWS ( 'Table' ),
    OR ( 
        'Table'[Preferred] = 'Table'[Sorted], 
        'Table'[Sorted] <> BLANK() && 'Table'[Preferred] = BLANK()
    )
)

Let me know if this helps 🙂

Thanks Parry, I am getting the result as "5" and not '4', i guess my one is counting the Blank cells (which is row 5 as both are blank) and as such giving 5. I wanted to get the result as just "4". Is there a way to sort it please?

@awsiya it will be easier if you add a column that compares the values and then simply sum on this new column:

Compare Column = 
INT ( COALESCE ( Table[Preferred], Table[Sorted] ), Table[Sorted] )

Sorted Matched Preferred Measure = SUM ( Table[Compare Column] )
