SUMX over all dates within a month

avanderschilden — Sun, 18 Aug 2019 10:03:54 GMT

Hello,

I have the following model;

I have a measure that calculates the number of reactivated users for each calendar date;

Reactivated Users = 
VAR _MaxDate =
    MAX ( 'D Calendar'[Date] )
VAR _CurrentUsers =
    CALCULATETABLE ( VALUES ( 'F Orders'[UserId] ), 'D Order'[IsCompleted] = "Yes" )
VAR _UserBefore60Days =
    CALCULATETABLE (
        VALUES ( 'F Orders'[UserId] ),
        'D Calendar'[Date] < _MaxDate - 60,
        'D Order'[IsCompleted] = "Yes"
    )
VAR _UsersLast60Days =
    CALCULATETABLE (
        VALUES ( 'F Orders'[UserId] ),
        'D Calendar'[Date] >= _MaxDate - 60
            && 'D Calendar'[Date] <= _MaxDate - 1,
        'D Order'[IsCompleted] = "Yes"
    )
VAR _Result =
    CALCULATE (
        DISTINCTCOUNT ( 'F Orders'[UserId] ),
        FILTER (
            ALL ( 'F Orders'[UserId] ),
            'F Orders'[UserId] IN _CurrentUsers
                && 'F Orders'[UserId] IN _UserBefore60Days
                && NOT 'F Orders'[UserId] IN _UsersLast60Days
        )
    )
RETURN
    _Result

I would like to display the total sum of all dates as the total for the month;

Does anyone have an idea how to achieve the desired result?

Many thanks in advance!

This looks like a measure totals problem. Very common. See my post about it here: https://community.powerbi.com/t5/DAX-Commands-and-Tips/Dealing-with-Measure-Totals/td-p/63376

Also, this Quick Measure, Measure Totals, The Final Word should get you what you need:

[Reactivated Users - Helper Measure] = -- hidden measure
// This measure works correctly on an individual
// day level.
VAR _MaxDate = MAX ( 'D Calendar'[Date] )

Dear Power BI team, give this man Anonymous a statue for his contribution to this forum!

Anonymous why is the daily number of reactivated users different from my first measure with a monthly total of 2226?

Greg_Deckler thanks for your reply and interesting posts!

"@darlove why is the daily number of reactivated users different from my first measure with a monthly total of 2226?"

I don't know. Is this wrong? You said you wanted to sum up all the reactivated users for all the days in the month in order to get the total for the month. This is what the measure does. Doesn't it?

The total sum of the daily numbers is correct. It is matching with a manual addition of all days so thanks a lot for that.

My doubts are based on the fact that your measure is producing a different daily result than my old measure, and I'm not sure which change you made in the new measure is creating this difference. Anyway, thanks again!

To know which is right you have to manually and carefully calculate the measure for some of the days. Take those days where there is a difference between the measures.
