Grand total of datediff not correct

Anonymous — Tue, 16 Jun 2020 19:10:15 GMT

I have a simple statement:

TimeToComplete = DATEDIFF([DateRaised],[DateCompleted],DAY).

I am able to filter by employee and the TimeToComplete column is correct for each of the employee's entries. However, the Grand Total is equal to the sum of all employees' TimeToComplete. I need to have the Grand Total be only the sum of the selected employee. What am I doing wrong? Thanks.

please explain what "selected employee" means. Selected where? In a slicer?

What's the data model looking like?

Dear,

I have the same issue, please allow me to explain.

From a report with time logs I have created 3 measures

Time Clock IN = calculate(MIN(Raw_data[Time]),FILTER(Raw_data,Raw_data[Gebeurtenis]="AccessOK"&&Raw_data[Ingang gebied]="CLock IN"))
Time Clock OUT = calculate(MAX(Raw_data[Time]),FILTER(Raw_data,Raw_data[Gebeurtenis]="AccessOK"&&Raw_data[Ingang gebied]="Clock OUT UIT"))
Time diff = IFERROR(DATEDIFF([Time Clock IN],[Time Clock OUT],MINUTE)/60,0)

Each single row (date / employee) result for the measure Time worked is correct, only the total or DateToMonth is showing the numbers as expected.

Any help is much appreciated !

Meantime I figured out how you can add up measures that are related to time stamps correctly.

1a) Original measure

Time Clock IN = calculate(MIN(Raw_data[Time]),FILTER(Raw_data,Raw_data[Gebeurtenis]="AccessOK"&&Raw_data[Ingang gebied]="CLock IN"))

2a) and then added another measure

Time Clock IN workable=if(countrows(values(DCalendar[Date]))=1,[Time Clock IN],sumx(values(DCalendar[Date]),[Time Clock IN]))

1b) Original measure
Time Clock OUT = calculate(MAX(Raw_data[Time]),FILTER(Raw_data,Raw_data[Gebeurtenis]="AccessOK"&&Raw_data[Ingang gebied]="Clock OUT UIT"))

2b) and then added another measure

Time Clock IN Correct=if(countrows(values(DCalendar[Date]))=1,[Time Clock OUT],sumx(values(DCalendar[Date]),[Time Clock OUT]))

3) Calculate hours worked

Nett time = IFERROR(DATEDIFF([Time Clock IN Correct],[Time Clock OUT Correct],MINUTE)/60,0)

4)a Deviation to calculate overtime hours

Time diff=[Nett Time]-[ContractHours]

4b) and then added another measure

Overtime hours correct= if(countrows(values(DCalendar[Date]))=1,[Time diff],sumx(values(DCalendar[Date]),[Time diff]))

Steps "b" are resulting in correct sum up / grand total.

I am very aware that steps "a" are not necessary to create, as you can integrate them in step b.

It is just to show you the direction how I solved my issue.

you have not specified what you expect the total to show. Should it be the sum of the computed values? In that case you need to use HASONEVALUE() or ISINSCOPE() to distinguish between individual items in the visual and the totals.

For the totals you would then have to use a SUMX function. Technically you could also use SUMX for the individual items but it would be overkill since it would ony ever sum up one item.

Hi Anonymous ,
This would be your measure:

DateDiff = IF(HASONEVALUE('Table'[Start]); DATEDIFF(MIN('Table'[Start]);MIN('Table'[End]);DAY); SUMX(SUMMARIZE('Table';'Table'[Worker ID];'Table'[Start];'Table'[End];"Diff"; CALCULATE(DATEDIFF(MIN('Table'[Start]);MIN('Table'[End]);DAY)));[Diff]) )

As seen here:

File is here.

Pls mark as solution if so. Thumbs up for the effort appreciated!

Groet, Steve.
