DAX to calculate the count of the flags

[deb_power123]

Hi All,

I have a table named student with columns DateBooked,ParticipantName and NoBookingCheckFlag. This data is corresponding to the students reservation for a school program.

The Date Booked column shows the booking date of the ticket,ParticipantName is the name of the student and NoBookingCheckFlag column shows those students who attended the program without reservation so if the flag is set to Yes then they attended the program without reservation and if flag is set to No the students attended the program with reservation.

Expected results :

I need to create a calculated measure column to find the remaining columns OverAllCount(with/without reservation,count(with reservation) and  %ge ratio corresponding to the respective booking dates. 

% age ratio = 1- count(with reservation)/OverallCount(with/without reservation)

Can you please suggest suitable DAX to handle the expected results?

Input source :

Date Booked	Participant Name	NoBookingCheckFlag	OverallAllCount(with/withoutreservation)	Count(WithReservation)	%geRatio
15.09.2021	Tom	Yes
16.09.2021	Tom	Yes
15.09.2021	John	Yes
16.09.2021	John	No
20.09.2021	Mary	Yes
21.09.2021	Mary	No
17.09.2021	Mary	No
13.09.2021	Elizabeth	Yes
14.09.2021	Elizabeth	Yes
09.09.2021	Mario	Yes
10.09.2021	Mario	Yes
17.09.2021	Mario	No
20.09.2021	Mario	No
21.09.2021	Mario	Yes

Kind regards

Hello there @deb_power123 ! If I understood your problem correctly, this is what you want:

Count (with reservation) =
CALCULATE(
COUNTROWS(Table),
Table[NoBookingCheckFlag] = "No")

OverallCount =
COUNT(Table[NoBookingCheckFlag])

% age ratio = 1 - DIVIDE( Count (with reservation), OverallCount)

As a side note, calculated measure column does not exist in PBI terminology since calculated column <> measure. Check out this link on the differences between both calculations.

Hope this answer solves your problem! If you need any additional help please @ me in your reply.

Hi @deb_power123 ,

Please use below measures:

OverAllCount(with/without reservation)= COUNT(NoBookingCheckFlag)

Count(with reservation)= CALCULATE(COUNT(NoBookingCheckFlag), Table(NoBookingCheckFlag)= "No")

 %ge ratio= 1- DIVIDE(Count(with reservation), OverAllCount(with/without reservation))

Mark this as a solution if I answered your question.

Thanks.
