Formula to pull max value based off another column

[gmasta1129]

Hello,

I would like to pull the maximum number in the "Total" column based off the customer account number. 

My data has thousands of rows. 

I need the maximum value to pull into the new column (see below) and the then the rest of the rows should show 0

For example,

I should see in the new column for customer number 5225, the number 10 since that is the highest number

I should see in the new column for customer number 6175, the number 21 sinc that is the highest number. The rest of the rows should show zero. 

I used the following formula in excel but cant figure out how to convert this to Power BI...

=LET(m,MAXIFS($Z$2:$Z$20000,$B$2:$B$20000,$B2), IF($Z2=m,m,0))

Customer Account Number     Total      New Column (Maximum Value)

5225                                            0                    0

5225                                          10                  10

5225                                           2                    0

5225                                           2                    0

5225                                           6                    0

6175                                           3                    0

6175                                            7                   0

6175                                            9                   0

6175                                            21                 21

Create a calculated column:

New Column (Maximum Value) =
VAR MaxValue = CALCULATE(
MAX('Table'[Total]),
ALLEXCEPT('Table', 'Table'[Customer Account Number])
)
RETURN IF('Table'[Total] = MaxValue, MaxValue, 0)

This approach will create a column in which only the row with the maximum value for each Customer Account Number shows the max value, while other rows display 0, just like in your Excel formula.
