Count of first ID

[Ubaid]

I have two columns one is of ID and other is of Date, ID is repeating on different dates but I want to calculate the first count of ID,

let supose ID "111" is created on 1-08-2022, then on 2-08-2022, 3-08-2022, and 5-08-2022, but I want to show the count of ID "111" on 1-08-2022 rest of the dates count should be blank for the ID "111"

Hi,

Please check the below picture and the attached pbix file.

It is for creating a measure.

Count of ID measure: =
VAR _currentdate =
    MAX ( Data[Date] )
VAR _currentidlist =
    VALUES ( Data[ID] )
VAR _currentidlistbeforecurrent =
    SUMMARIZE (
        FILTER ( ALL ( Data ), Data[ID] IN _currentidlist && Data[Date] < _currentdate ),
        Data[ID]
    )
VAR _currentidcount =
    COUNTROWS ( _currentidlist )
VAR _beforecurrentidcount =
    COUNTROWS ( _currentidlistbeforecurrent )
RETURN
    IF ( HASONEVALUE ( Data[Date] ), _currentidcount - _beforecurrentidcount )

@Ubaid . Create a flag and use that in filter

a new column

flag = if([Date] = minx(filter(Table, [ID] =earlier([ID]) ), [Date]) , 1, 0)
