DAX to eliminate blank values

[prv_1401]

Hi all, 
I have columns 'ID' and 'PO'
PO columns has values 0, 100 and blank cells.
I want the count of ID where PO = 0 (only). But even the blank gets counted.
I have used this dax to eliminate blank but still I dont get the output desired. I get blank value instead .
Please help.

SKUswith0 = CALCULATE(

    DISTINCTCOUNT('Master Data'[id]),

    'Master Data'[PO] = 0 && 'Master Data'[PO] <> BLANK())

Hi: You can try this measure:

SKUswith0 = CALCULATE(COUNTA('Mater Data'[PO]), 'Mater Data'[PO] = 0)

Good luck!

Hi,

In the Query Editor, change the data type of the PO column to Text.  Now try this measure

SKUswith0 = CALCULATE(DISTINCTCOUNT('Master Data'[id]),'Master Data'[PO] = "0")

If you do not want to change the data type, then try this measure

SKUswith0 = CALCULATE(DISTINCTCOUNT('Master Data'[id]),'Master Data'[PO] == 0)

Hope this helps.
