Count values between dates

[Anonymous]

Hi all! 

I need a DAX measure to count items between dates, example:

item	start	end
A	01/01/2022	03/01/2022
B	05/01/2022	10/01/2022
C	04/01/2022	06/01/2022
D	02/01/2022	08/01/2022
E	07/01/2022	09/01/2022

Result with DAX:

calendar[date]	quantity item	ref item
01/01/2022	1	A
02/01/2022	2	A, D
03/01/2022	2	A, D
04/01/2022	2	C, D
05/01/2022	3	B, C, D
06/01/2022	3	B, C, D
07/01/2022	3	B, D, E
08/01/2022	3	B, D, E
09/01/2022	2	B, E
10/01/2022	1	B

Obs: column "ref item" in second table only illustrative, not consider

Can you help?

Hi, @Anonymous 

You can try the following methods.

Table:

calendar = CALENDAR(MIN('Table'[start]),MAX('Table'[end]))

Measure:

quantity item =
CALCULATE (
    COUNT ( 'Table'[item] ),
    FILTER (
        ALL ( 'Table' ),
        [start] <= SELECTEDVALUE ( 'calendar'[Date] )
            && [end] >= SELECTEDVALUE ( 'calendar'[Date] )
    )
)

Is this the result you expect?

@Anonymous , first expand between dates in power query

Then you can concat in power query of in DAX

The  first step can be done in DAX too , and a measure with help from cancatenatex

@amitchandakthanks for replying!

This solution works perfectly but it expands the table according to the date range.

When you have a lot of data, the load becomes very heavy.
