Wrong output with specific filter

[Anonymous]

Hi everyone,

I'm rather new to Power BI and I just came across a weird error.

When I filter a Card visual that sums up a number of times an event has happened, it always shows the correct value expect for when I date slice August and a specific name. Every ouput is correct no matter what I filter for, only for this specific month in combination with a specific name, the output shows 8 when it should say 9 (i checked in the dataset and the event happend 9 times in that month with that name)

Thanks a lot!

@Anonymous What is your measure formula or are you using a simple count aggregation or ?

@Greg_Deckler 

CALCULATE(COUNTA(Addresses[Date of Appointment]), USERELATIONSHIP(Addresses[Date of Appointment], 'Date'[Date]))

[Greg_Deckler]

@Anonymous Any chance the Date of Appointment in Addresses for one row happens to be blank? COUNTA doesn't count blanks and that row might also get filtered via the relationship.

Unfortunately I can not look into the dataset at the moment. But If that was the case, can I rewrite the measure in any way so it ignores blank rows?

I've tried this and it doesn't solve the issue:

CALCULATE(count(Addresses[Date of Appointment]), NOT(ISBLANK(Addresses[Date of Appointment])), USERELATIONSHIP(Addresses[Date of Appointment], 'Date'[Date]))

@Anonymous Well, the measure is already ignoring blank rows. COUNTA doesn't count blanks.

I just checked and the Date of Appointments in Addresses has some empty rows. Any ideas on what to try now?

@Anonymous I'm really confused. If you don't want to count those blank rows then you can do absolutely nothing. If you want to count those blank rows, then:

CALCULATE(COUNTA(Addresses[Date of Appointment]), USERELATIONSHIP(Addresses[Date of Appointment], 'Date'[Date])) + CALCULATE(COUNTBLANK(Addresses[Date of Appointment]), USERELATIONSHIP(Addresses[Date of Appointment], 'Date'[Date]))

or:

CALCULATE(COUNTROWS(Addresses), USERELATIONSHIP(Addresses[Date of Appointment], 'Date'[Date]))
