Count how many values of one variable are in another variable

[cris1196]

Hello everyone. I have this table

(https://docs.google.com/spreadsheets/d/11g-BxXQ-AjcXMVl2h_Yji3bk63BqKxLw/edit?usp=sharing&ouid=10668...)

and I want to create something similar to this

The only way I could think of to do this is:

Measure =
var SelectedMonth = selectedvalue(T1[YearMonth])
var AllUserMonth= All users who bought in SelectedMonth , filtered by first_order = True

//Then:
Var Day01= All users who bought on day one (Daydate=1), filtered by SelectedMonth
Var Day02= All users who bought on day two (Daydate=2), filtered by SelectedMonth
Var Day03= All users who bought on day three, filtered by SelectedMonth

etc.... untill

Var Day31= All users who bought on day 31, filtered by SelectedMonth

//So, here at the end, make a Count of  "how many Day01 users there are in AllUserMonth"; "how many Day02 users there are in AllUserMonth"..... etc untill Day31.

So, I need a way to calculate "how many values of one variable are in this other variable". I tried several ways with addcolumns but no success. 

I know this is inefficient, that if the SelectMonth doesn't work I'll have to create a variable for each month and then day variables for each month... but I have no problem writing all that (And it's the only way I could think of that could replicate the Excel table in PBI 😣)

Any help is welcome, thanks 🙂

嗨@cris1196，

You can get the required date like this:

VAR _CUR_DATE = MAX('T1'[ORDER_DATE])
VAR _DATE_MIN = DATE(YEAR(_CUR_DATE),MONTH(_CUR_DATE),DAY(_CUR_DATE))
VAR _DATE_MAX = DATE(YEAR(_CUR_DATE),MONTH(_CUR_DATE),DAY(_CUR_DATE))+1

Please feel free to let me know if I misunderstood your needs. It would be helpful if you could attach the measure you created for each day below.
