Count Blanks Based on Two Columns Within Month

[BrianNeedsHelp]

I'm trying to Count the number of blanks across date range filtered to a month, where it counts only if both columns are blank for a particular day.   Like this:   

	10/1/2024	10/1/2024	10/2/2024	10/2/2024	10/3/2024	10/3/2024	Count Blanks
	Sales	Upsales	Sales	UpSales	Sales	Upsales
Customer A	3		1	1			1
Customer B	4	5	1	7	2	3	0
Customber C		1					2

I couldn't use CountBlank, because I kept getting "parameter is the wrong type" even though I used Value([Sales]), so I tried like this CountBlanks = COUNTROWS(FILTER('Sales Table', ISBLANK([Sales] && ISBLANK([Upsales])))), but it didn't populate anything.  If I just use one side of the && statement, it populates wild values.   Any way to make this work?

Hi @BrianNeedsHelp 

Here's a sample for your reference:

Sales Table:

Then add a measure:

CountBlank =
VAR _currentCustomer =
    SELECTEDVALUE ( 'Sales Table'[Customer] )
RETURN
    CALCULATE (
        COUNT ( 'Sales Table'[Date] ),
        FILTER (
            ALLSELECTED ( 'Sales Table' ),
            'Sales Table'[Sales] = BLANK ()
                && 'Sales Table'[Upsales] = BLANK ()
                && 'Sales Table'[Customer] = _currentCustomer
        )
    )

The result is as follow:

The above examples are for your reference, and you need to adjust the visualization yourself.

Thank you, but it only needs to count blank if both fields are blank within the date.   And is there a way to hide the CountBlanks field within the dates and just show a sum total at the end of the row?

Hi @BrianNeedsHelp 

The matrix does not currently support the ability to hide fields, so you can only make it appear empty

Please try this:

CountBlank =
VAR _currentCustomer =
    SELECTEDVALUE ( 'Sales Table'[Customer] )
RETURN
    IF (
        NOT HASONEVALUE ( 'Sales Table'[Date] ),
        CALCULATE (
            COUNT ( 'Sales Table'[Date] ),
            FILTER (
                ALLSELECTED ( 'Sales Table' ),
                'Sales Table'[Sales] = BLANK ()
                    && 'Sales Table'[Upsales] = BLANK ()
                    && 'Sales Table'[Customer] = _currentCustomer
            )
        )
    )

The result is as follow:

For the sum column of Sumofeles and Sumofopsales, you can also create Messur to do the same, for example:

_Sales = IF(HASONEVALUE('Sales Table'[Date]),SUM('Sales Table'[Sales]))

_Upsales = IF(HASONEVALUE('Sales Table'[Date]),SUM('Sales Table'[Upsales]))

The result is as follow:

@Anonymous I got the code inputted with no errors, but in the Total I get the number 31 in all of the rows.  So it's like it's saying there are blanks every day for the whole month.

Hi @BrianNeedsHelp 

Could you please provide more raw data in your tables (exclude sensitive data) with Text format and your expected result with backend logic and special examples? It would be helpful to find out the solution. You can refer the following links to share the required info:

And It is better if you can share a simplified pbix file. You can refer the following link to upload the file to the community. Thank you.

Thx for checking, but I ended up doing something much simpler:  

CountBlanks = IF(ISBLANK([Gross Adds])&&ISBLANK([Device Upgrades]), 1, 0)

Then I put in a measure to sum the CountBlanks:    

#DaysZero = SUMX(VALUES('Calendar'[CalendarDate]),[CountBlanks])

So the Locations are in a different table, so I'm having trouble with the last part of the code.  I have this:  

Blanks = VAR _currentCustomer =
    SELECTEDVALUE ( 'Current Hierarchy'[Location] )
RETURN
    IF (
        NOT HASONEVALUE ('Calendar'[Calendar Date] ),
        CALCULATE (
            COUNT ( 'Calendar'[Calendar Date]),
            FILTER (
                ALLSELECTED ( 'Sales'),
                'Sales'[Sales]= BLANK ()
                    && 'Sales'[Upsales]= BLANK ()
                     && 'Current Hierarchy'[Location]=_currentCustomer
            )
        )
    )

The Customer is [Location] is in a different table, so it's not allowing me to add in 'Current Hierarchy' [Location]that in under the All Selected ('Sales')table.  Can that be reformatted to add that part?

I keep getting "Your post has been changed because invalid HTML was found in the message body."  I clicked on the table and selected only one square like the instructions and pasted from a spreadsheet.  I'm needing to know how I can count blanks if two columns are blank.  If there are dates going across the top of the table 10/1 10/2 10/3 etc.  Each date has two columns, Sales and Upsales.  If both columns are blank that should count as 1.  The Count Blanks column would have the total number of blanks across the whole date range.
