Row total does not correct with Matrix

[TracyTran]

Hi friends, 

I faced challenges in determining the total sales from new customers within a user-selected time period.

New_customers_Sales = 
VAR CurrentMonth = SELECTEDVALUE('D_Date'[End of Month])
var result = 
CALCULATETABLE(
    VALUES(F_Order[customerid]),
    F_Order[First Order Date (EOM)] = CurrentMonth
)
return 
SUMX(result, CALCULATE([sale_Amount]))

I encountered an issue with the Matrix visual where the row total does not display accurately.

 The desired output with correct row total:

Hi @TracyTran ,

The problem you are facing may be due to the context in which the totals are calculated.Power BI calculates totals based on the context of the entire table, which may not always match the expected results when using complex metric values that involve filters or specific row contexts.
DAX overview - DAX | Microsoft Learn
To solve this problem, you can try using the "HASONEVALUE" function to modify the behavior of the metric when calculating the total.
HASONEVALUE function (DAX) - DAX | Microsoft Learn
Please provide some sample data so I can try to modify DAX for you.
