Count same values from the most recente date

[Anonymous]

Hi everyone,

I want to create a formula which count how many times a specific value shows up in the most recent date.
I made a sample set (see below). I want to know how many times '-1' shows up in the latest month (March). So the answer should be 3.  

Date	Aspect	Value
January 2020	Responsibility	1
January 2020	Validity	0
January 2020	Satefy	-1
January  2020	Guarantee	-1
February 2020	Responsibility	0
February 2020	Validity	-1
February 2020	Satefy	0
February 2020	Guarantee	0
March 2020	Responsibility	-1
March 2020	Validity	-1
March 2020	Satefy	-1
March 2020	Guarantee	1

measure =
var _sel = -1
return
calculate(count(table[Value]),Table[date] = format(today(),"MMMM YYYY"),table[value] =_sel)

Hi @amitchandak ,

Thanks for your reply. 

I cannot see if the measure works, because Power BI shows me the following:

Cannot load the data for this visual

In DAX-comparisons it is not supported to make comparisons of values of type Date with values of type Text. 

I don't understand this, since the column Value is the type 'Whole value' and not 'Text'.

Hi, @Anonymous 

Try  adding  format function to “Table”[Date]:

measure = 
var _sel = -1
return
CALCULATE(COUNT('Table'[Value]),FORMAT('Table'[Date],"MMMM YYYY")=FORMAT(TODAY(),"MMMM YYYY"),'Table'[Value]=_sel)
