获取总行 DAX Power BI 的正确总和

Question

I have: Dim Table: Accounts: customer granularity level.

Fact Table: PhoneCalls. calls to customers granularity level.

I need to create and see the number of calls made to a customer up until the customer made their first deposit.

I was able to do this on the customer level but on the Total level I get a weird result:

my measure:

ACC_Calls_2_FDP = 
CALCULATE(
    COUNTROWS(PhoneCalls),
    PhoneCalls[disposition] = "ANSWERED", -- only calls that were answered
    PhoneCalls[calldate] <= MAX(Accounts[FDP_Date]), -- up until FDP date per customer
    USERELATIONSHIP(Accounts[AccountNo],PhoneCalls[AccountNo]) -- make the connection active
)

the results are:

On the total level i was expecting to see 14. not 536 what is going on? what am i missing?

The data model: Filter direction: Accounts filters PhoneCalls Cardinality 1:*

Answer 1

Power BI doesn't sum up each of the row values as in Excel. Instead, for Grand total value they will still calculate it as a row itself with no filters on AccountNo on it.

In this case, the max value of FDP_Date in the whole table is taken in the measure. So for example, ACC 1 has max date of 3, ACC 3 has the max of 10. The grand total calculation will use 10 as the max value and start countrows on whichever rows with FDP_Date < 10.

To fix this is tricky as I don't have any other information than this. However, I hope this explains you well of the "bug".
