## Cumulative distinct count

Hi all,

I have a table with order, date and customer and I would like to count the number of cumulative orders per customer.

Currently I have:

Measure = CALCULATE(DISTINCTCOUNT('Table'[Order]),FILTER(ALLSELECTED('Table'),'Table'[Order]<max('Table'[Order]))).

This works but I would like to have it counted per customer without having to filter them. (Expected results: 0-1-2-2-0-1-0-1). In addition, I'd like to know how to do the same thing with a calculated column, since using the formula as is returns only 1 number.

Thx,

Joery

You may try to create a measure or column as below:

```Measure =
CALCULATE (
DISTINCTCOUNT ( Table1[Order] ),
FILTER (
ALLEXCEPT ( Table1, Table1[Customer] ),
Table1[Order] < MAX ( Table1[Order] )
)
)
+ 0```

```Column =
CALCULATE (
DISTINCTCOUNT ( Table1[Order] ),
FILTER (
Table1,
Table1[Customer] = EARLIER ( Table1[Customer] )
&& Table1[Order] < EARLIER ( Table1[Order] )
)
)
+ 0```

Thank you! There is one issue though.

This works perfectly in my test-dataset but calculating the column is too heavy in the actual one. Dataset is currently ~155k rows. Is there any way to do this more efficiently?

You may also try to make a query with M language in Advanced Editor in Query Editor. It seems a more complicated way.
