countrows ignoring filter

hello,

trying to compare a count of multiple transaction vs single transactions.

i have a table with 2 columns, first one is GATEVISITNUMBER, second column is NBR

GATEVISITNUMBER is the primary key, and NBR is a unique number that represent different transaction associated with GATEVISITNUMBERS

for example:

GATEVISITNUMBER     NBR

1                                   1

1                                   2

2                                   3

3                                   4

4                                   5

4                                   6

5                                   7

my measures:

count nbr measure = count(N4_TruckTransactions[NBR])
single transaction = CALCULATE(count(N4_TruckTransactions[GATEVISITNUMBER]),filter(N4_TruckTransactions,[count nbr measure]=1))
double transaction = CALCULATE(count(N4_TruckTransactions[GATEVISITNUMBER]),filter(N4_TruckTransactions,[count nbr measure]=2))

but however the Single measure is returning all rows
and Double measure returning blanks.

what am i doing wrong? or if there is a better way to do this?

thank you

Please try this small change instead.  There is something called context transition that happens with you use a measure in your FILTER evaluation.  It is a good thing but, since you are filtering the whole table, a filter is created on both columns and every row returns 1.  That is what your first one gets all rows and your second one gets none.  To get your desired result, you just want to filter the one column.

single transaction =
COUNTROWS(
FILTER (
DISTINCT ( N4_TruckTransactions[GATEVISITNUMBER] ),
[count nbr measure] = 1
)
)

And then use same but with = 2 for second measure

thanks Pat ,

it works!

😀👍

but can you explain a little more on
"a filter is created on both columns and every row returns"

still don't understand why first measure returns all rows and second returns blanks.

i first thought calculate() and filter() always goes together, but apperently not.

and when do I need to use the calculate() ?
