DAX - Count number of months by customer in a Table Visual filtered by Date

[arlequin71]

Hi, can anyone help me on this....

I need to create a metric for counting the number of months in range of Date(month) field at customer level for selected customers on selected months in the filtered table.

In the attached example the number of months is 2 for Customer 1, the Max Date is November and the min Date is October.  It would be needed to consider End of Month in max Date.

Thanks in advance for any tip.

regards.

Hi, thanks for your answer but it doesn't work in my case.   

I need to eliminate filter context in the table to be able to use a Dax like this example :

Count Months = Countrows(Filter(SUMMARIZE('Total Sales by Date by Dept','Total Sales by Date by Dept'[CUST_NM],'Total Sales by Date by Dept'[Date(month)],"sum months",sum('Total Sales by Date by Dept'[Total Sales])),[sum months]>0))

inside the table visual whith no inluence of other filters.

Thanks in advance.

Hi, @arlequin71 

Based on the above information, to get the Month column using the following measure

Count Months =
CALCULATE (
    DISTINCTCOUNT ( 'Total Sales by Date by Dept'[Date(month)] ),
    FILTER (
        ALLSELECTED ( 'Total Sales by Date by Dept' ),
        'Total Sales by Date by Dept'[CUST_NM]
            = MAX ( 'Total Sales by Date by Dept'[CUST_NM] )
    )
)

 Or, please share your sample pbix file's link here, then I can try to look into it to come up with a more accurate measure.

"It would be needed to consider End of Month in max Date"

Not really. All you need is DISTINCTCOUNT(FORMAT([date],"yyyymm"))
