Count the no if ID

[Yau0101]

Dear All,

How can I count the no of ID in the ID column as shown in the picture below? The total no of ID should be 48. Basically the id is the quotation id, i want to know the number of quotes issued in month of september.  Please advise. thanks

@Yau0101 ,  a Measure

Calculate(count(Table[ID]), Filter(Table, eomonth(Table[created_date],0) = eomonth(today(),-1) )) 

Or you can use time intelligence with date table

last MTD Sales = CALCULATE(count(Table[ID]),DATESMTD(dateadd('Date'[Date],-1,MONTH)))
last month Sales = CALCULATE(count(Table[ID]),previousmonth('Date'[Date]))
