count multiple rows together

[Anonymous]

Hi !

I have a table named ShipDetails that looks like this :

DROP	ON_TIME_DELIVERY	ORDERED_PRODUCT
Client 1 - Order 1	OK	Product 2
Client 1 - Order 1	OK	Product 4
Client 2 - Order 1	KO	Product 1
Client 2 - Order 1	KO	Product 2
Client 2 - Order 1	KO	Product 3
C1 - O2	KO	Product 3
C1 - O3	OK	Product 3
C1 - O3	OK	Product 4

I would like to create a measure that count the percentage of on time delivery.

In order to do that, I have to count 1 if ON-TIME_DELIVERY is "OK" and 0 if it's "KO", FOR EACH DROP (and then divide by the number of distinct drops).

It's easy to do it for each row, but, here, rows of the same drop have to be counted only as 1.

How could I do it ?

(I tried several measures like this one but it doesn't work at all : On time delivery (%) = CALCULATE(SUMX(ShipDetails,IF(ShipDetails[ON_TIME_DELIVERY]="OK",1,0)),ALLEXCEPT(ShipDetails,ShipDetails[DROP]))/DISTINCTCOUNT(ShipDetails[DROP]))

Thank you for your help,

Regards,

Marion

Hi @Anonymous 

Try this.

On time delivery (%) = 
DIVIDE(
    CALCULATE(
        DISTINCTCOUNT( ShipDetails[DROP] ), 
        ShipDetails[ON_TIME_DELIVERY] = "OK" 
    ),
    DISTINCTCOUNT ( ShipDetails[DROP] )
)

Best Regards,
