DAX COUNTROWS is overcounting and MEASURE COUNTROWS is undercounting AAAAARG!!

[tj1947]

I have a table with three rows

serialnumber          Actual Ship Date     SchedShip           On Time
211028-23-M34     2024-02-27             2024-02-27         1
211027-23-M34     2024-02-27             2024-02-28         1
220224-12-M11     2024-02-28             2024-02-23         0

I'm trying to get DAX or a MEASURE to return the correct rowcount.

The Measure below returns "2"

     COUNTROWS('On Time Delivery')   

The DAX Column below returns "6"

    COUNTROWS('On Time Delivery') 

I have also tried COUNT('On Time Delivery'[SerialNumber]) 

I have also tried COUNT(DISTINCT('On Time Delivery'[SerialNumber]))

Nothing returns "3" which is what I'm expecting.

Hi, @tj1947 

Based on your description, I have created some measures to achieve the effect you are looking for. Following picture shows the effect of the display.

Measure:

COUNTROWS = CALCULATE(COUNTROWS('On Time Delivery'))

If this does not work, I observe that your table has its own filters and Measure, and it may be that these filters are affecting the final realization; you can provide your own data in full and the effect you want to achieve.

Hey @tj1947 ,

what do you event want to do?

If you use filter or slicer, the table will be filtered. Then the rowcount is less.

How did you even get 6 when there are only 3 rows?

Please provide a sample file or at least more context. Like this I don't think anyone can help you.

Best regards

I was trying to get an accurate count of the rows.  I have no idea how/why it was returning 6 when there were only 3 rows, hence my confusion and posting here for help.  

No worries, though!   v-yaningy-msft was able to help.  Adding CALCULATE to my COUNTROWS measure worked like a charm.
