Result same period last year is correct for the subtotal, but sometimes blank in details

[haraldjw]

Who can help me with the following problem?

The formula 'Result same period last year' gives correct values for the subtotal, but details are blank for those rows where the result for this year is blank.

DAX-formula:

Resultaat vorig jaar = CALCULATE(sum('FACT-GrootboekMutaties'[Bedrag])*-1,'DIM-Grootboek'[GrootboekType]="P",SAMEPERIODLASTYEAR('DIM-Kalender'[Date]))

For example:

• Subtotal        1.000
• Fuel        500
• Tax        300

When asking for the 'Result this year' while filtering last year, it shows the correct results.

• Subtotal        1.000
• Fuel        500
• Tax        300
• Lease        200

Thanks for your help!

You should not include calculation in the expression (*-1), put it outside the calculate function like below.

Resultaat vorig jaar = CALCULATE(sum('FACT-GrootboekMutaties'[Bedrag]),'DIM-Grootboek'[GrootboekType]="P",SAMEPERIODLASTYEAR('DIM-Kalender'[Date]))*-1)

Instead of using 'DIM-Grootboek'[GrootboekType]="P" as an internal filter context , remove that and use as an external and see whehter it works! I am thinking the issue with Internal Filter context!

@VijayP @Thanks for your help. I even removed the filter but it makes no difference.

I can't find out why the totals are shown correct, and individuals lines are empty, only when the result of this year is empty.

@haraldjw , Please make sure calendar table is marked as date table

also Try

Resultaat vorig jaar = CALCULATE(sum('FACT-GrootboekMutaties'[Bedrag])*-1,'DIM-Grootboek'[GrootboekType]="P",dateadd('DIM-Kalender'[Date],-1,year))

[haraldjw]

@amitchandak The calender is marked as date table (of course).

The strange thing is: Why are the subtotals correct? And those details missing where the value of this year is blank?

[amitchandak]

@haraldjw , very difficult to tell without looking at data.Can you share sample data and sample output in table format? Or a sample pbix after removing sensitive data.

@amitchandak I appreciate your help! Can you send me a PB where to send the file?
