Count a Measure or Countif

[Corleen]

Good day

Please assist

I've created a measure to count how many times a person id comes forth in the data.

# times = CALCULATE(COUNT('TransactionDetails'[SYSTEM_NUM]),'TransactionDetails'[EARN_DEDUCT_IND]=1)

What I would like to do is now is count how many people transacted once, how many people transacted twice and so on. Also make a interval for example transacted 15-25 times. In Excel it would be something like this countif(A2:A500,1)

I've tried the if statement in Power BI  if(# times = 1, count([# times])) but you can't count that measure.

Any ideas or better way to approach this will be appreciated 

Thank you

Hi @Corleen

This worked for me (I think)

# Times = CALCULATE(
				COUNTROWS('Table1'), 
				FILTER(
					'Table1',
					'Table1'[SYSTEM_NUM] = MAX('Table1'[SYSTEM_NUM])
					)
				)

Thank you for your reply.

But it is a measure not a calculated column 

For eg.

Trans Once = count([# times] = 1) I want the answer for this, how to do this?

Trans Twice = count([# times] = 2) ect.

where 

[# times] = CALCULATE(COUNT('TransDetail'[SYSTEM_NUM]),'TransDetail'[EARN_DEDUCT_IND]=1)  (this is a measure)

Thanks

Can you try the same formula for the measure and check what it results?

[Corleen]

# times =

CALCULATE(

                   COUNTROWS('TransDetail'),

                                          ALLEXCEPT('TransDetail',

                                                                                 'TransDetail'[SYSTEM_NUM],

                                                                                   'TransDetail'[EARN_DEDUCT_IND]=1) 'the underline part gives an error'

)t

! A single value for column EARN_DEDUCT_IND  in TransDetail cannot be determined. THis can happen when a measure formula to a column that contains many values without specifying an aggregation such as min, max, count or sum to get to a single result.

Is this what you meant?

@Corleen,

Please try the DAX below.
# times =
CALCULATE(
                    COUNTROWS('TransDetail'),
                    FILTER(ALLEXCEPT('TransDetail',                                                                                        
                                                  'TransDetail'[SYSTEM_NUM]), 

                               'TransDetail'[EARN_DEDUCT_IND]=1)
                    )

remove =1

[Corleen]

I have removed the 1 and it gives me a result.

But not the result what I want.

Would please explain the Measure to me

Thank you

This measure simply count the number of rows in SYSTEM_NUM that matches each row in EARN_DEDUCT_IND no matter what is the value in EARN_DEDUCT_IND

Hi Corleen,

Usually you can use below in counting reference to a column

CALCULATE (
    COUNTROWS ( 'TableName' ),
    ALLEXCEPT (
        'TableName',
        'TableName'[Coulmn_you_want_to_count],
        'TableName'[Reference_Coulmn],
        )
)

I think if you gave this a try you will have all you need in one column

#times = CALCULATE(COUNTROWS('TransDetail'),ALLEXCEPT('TransDetail','TransDetail'[SYSTEM_NUM],'TableName'[EARN_DEDUCT_IND],))

It will count all trnx that have EARN_DEDUCT_IND = 1, 2, 3, ...etc and place it in one column
