How to calculate the right "Not assigned" orders (PO type) by filtering order PO types

[Humberto1959]

I want to countdistint ordernummers that has unassigned as PO type excluding the one which has also other PO types.

I made this DAX formula but it does not work

Column 2 =

(IF('Automatic orders'[Po type]="Not assigned",DISTINCTCOUNT('Automatic orders'[order number])))-(IF('Automatic orders'[Po type]="Not assigned",

IF(

COUNTX(FILTER('Automatic orders',[order number]=EARLIER('Automatic orders'[order number])),[order number])=1,

1,0),0))

order number	Po type

348440249	Not assigned

Please try this code:

Corrected the code

Hello jemaszhang0805, sorry for my late reaction. No failurues popping up but it only counts the rows which is 79  but the result should be 43.

[jameszhang0805]

@Humberto1959 

My code is just based on the data source you provided. I created a pivot table in Excel it returned the same result. So maybe it's the other columns in your original data source that are affecting the filtered result.

[Humberto1959]

It is right. I have made a column just for this table but it does not work and unfortunatily I can not attache the power bi file.  See picture.

[jameszhang0805 · Accepted solution]

@Humberto1959  if you put the code into the column, it will generate the wrong result. Because my code is used to put into a measure. 
For calculate column code:

CorrectPOColumn = 
VAR _NormalPO =
    CALCULATETABLE (
        SUMMARIZE ( 'PO Detail', 'PO Detail'[order number] ),
        'PO Detail'[Po type] <> "Not assigned"
    )
VAR _Notassiged =
    EXCEPT ( VALUES ( 'PO Detail'[order number] ), _NormalPO )
RETURN
    IF( 'PO Detail'[order number]   in _Notassiged ,1 ,0)

Thnx jameszhang0805, it is working now.

Sorry wrong picture,

@Humberto1959 Did the above code solve your problem?

[Humberto1959]

Hello AntrikshSharma,  for both solutions it is only counting the rows in the table which is 79. The result should be 43.

@Humberto1959 , A measure with only Not assigned

countx(filter(summarize(Table, Table[order number], "_1", distinctCOUNT(Table[Po type]) , "_2", calculate(distinctCOUNT(Table[Po type]), filter(Yable, Table[Po type] ="Not assigned"))), [_1] =[_2]), [order number])

[Humberto1959]

Hello amitchandak, sorry for my late reaction. The DAX formula does not give a syntax or other failures when creating a new colum but is counts only the rowes in my table namely 79
