Sum based on other columns

[Anonymous]

How do I calculate the sum of Hours based on ProjectNum and Assignee Name? 

If I just sum the Hours column, the expected value doubles or more. I also tried creating a new column using sum and allexcept, but didn't work.

Note: Hours is a calculated column. 

Data we have:

ProjectNum |  AssigneeName  |  Hours

123                 Ann                       2

123                 Ann                       5

456                 Joe                        3

456                 Joe                        7

456                 Ann                       4

Output should be:

ProjectNum |  AssigneeName  |  TotalHours

123                 Ann                       7

456                 Joe                        10

456                 Ann                        4

Thanks.

Make sure 'ProjectNum' is set to 'Do not summarize'

Hey, thanks. Yes, it is set to Don't summarize. Still didn't work. 😞

Ok, help me and I'll help you. Show me what you have or attach the pbix

Unfortunately, I don't find any option to attach a file.

Below is the formula I used for calculating TotalHours:

TotalHours = CALCULATE (

MAX( 'Table'[Hours] ),

ALLEXCEPT( 'Table', 'Table'[ProjectNum], 'Table'[AssigneeName]

))

And then I use SUM on the Hours coulmn instead of Don't Summarize. It then doubles the expeced value.

In the formula, if I use SUM( 'Table'[Hours] ) intead of MAX( 'Table'[Hours] ), it doubles the value for each row.

A simple explicit measure:

MTotal Hours = SUM(Table[Hours])

added to a table visualisation which has ProjectNum (do not summarize) and Assignee should give you this

Thank you for this. It should work, but for my data set it is not. The sum seems to double because there are duplicate rows with respect to the Hours Field in the data set.

Hello,

A different column called 'Date' was causing the duplicates. I craeted a calculated column by taking the max of this Date and gave it a value 1 and then applied a page level filter by 1.

The formula for max looks like the one below:

MaxDate = IF('Table1'[Date]=CALCULATE(MAX('Table1'[Date]),ALLEXCEPT(Table1,'Table1'[column1], 'Table1'[column2])),1,0)

After this sum will work for the 'Hours column'. 😄
