Measure for Count of opened items during last 30 days

[ymirza]

I am looking for DAX that will count the number of Opened tasks during the last 30 days and 90 days. 

I have this simple table below

Task	Created
Opened	01-Dec
Closed	02-Dec
Closed	02-Dec
Closed	04-Dec
Opened	05-Dec
Opened	06-Dec
Opened	07-Dec

I will use Card to display this count

try this formula

Last 30 days =
CALCULATE (
     COUNT( Table[Task_ID] ),
              FILTER (
                   ALL ( Table ),
                  Table[date]
                   >= MAX ( Table[date] ) - 30
                   && Table[date] <= MAX ( Table[date] )
                   && Table[Task] = "Opened"
                           )
)

@themistoklis, thank for quick response. What is the Table[value] you are using from? i dont have any such column

@ymirza

I have amened the previous formula,

I have put task_Id instead of value and count instead os SUM.

In other words this is the place where you count the number of tasks.

I dont know which field identifies the tasks so i have just put Task_ID (which you can replace with the relevant field)

Thanks @themistoklis, it is working now. Can you also amend for values returning Blank?

Try this:

Last 30 days =
CALCULATE (
     COUNT( Table[Task_ID] ),
              FILTER (
                   ALL ( Table ),
                  Table[date]
                   >= MAX ( Table[date] ) - 30
                   && Table[date] <= MAX ( Table[date] )
                   && Table[Task] = BLANK()
                           )
)

OR 

Last 30 days =
CALCULATE (
     COUNT( Table[Task_ID] ),
              FILTER (
                   ALL ( Table ),
                  Table[date]
                   >= MAX ( Table[date] ) - 30
                   && Table[date] <= MAX ( Table[date] )
                   && LEN[Task] = 0
                           )
)
