calculate value between two chosen filtered months

Anonymous — Tue, 23 Aug 2022 10:59:53 GMT

i have a filter with 5 months values, lets say i have chosen 01.2022 and 03.2022.

i have an income column that contains income value for all dates within each month.

The problem:

i need to sum up income for all days in 01.2022 and 03.2022 and calculate the difference between the two months, i.e. income for max month - income for min month.

this should work with whatever 2 months i choose in the filter.

i have googled and couldn't find any solutions to this problem.

is this even possible?

Hi Anonymous

For this you can use the Date Filter to set Max Min Range of Dates. Follow the instructions from the link:

i can't see how that will solve my problem.

i have a table visual with month and total_income and difference.

it should look like the following:

my problem is how to calculate the difference part, based on ANY chosen months in the filter.

Please try

Difference = VAR SelectedMonths = ALLSELECTED ( TableName[Month] ) VAR MaxMonth = MAXX ( SelectedMonths, TableName[Month] ) VAR MinMonth = MINX ( SelectedMonths, TableName[Month] ) VAR MaxValue = CALCULATE ( [Income], TableName[Month] = MaxMonth ) VAR MinValue = CALCULATE ( [Income], TableName[Month] = MinMonth ) RETURN MaxValue - MinValue

that didn't work either 😞

what i have done so far which gets me a little on the way is the following:

Index = RANKX(Prognosemodell_Prognose_Total_Test_Historikk, Prognosemodell_Prognose_Total_Test_Historikk[prognose_dato], , ASC, Dense)

i.e. i have created an index for the month, which means the last month has the highest index and the oldest months have index 1.

then i used this to pick up the value for the highest index chosen - 1, i.e. i can see the difference between the highest chosen index and the next on the list.

inntekter forrige = CALCULATE (

SUM ( Prognosemodell_Prognose_Total_Test_Historikk[Inntekter] ),

FILTER (

ALLEXCEPT ( Prognosemodell_Prognose_Total_Test_Historikk,date_dim[Date] ),

Prognosemodell_Prognose_Total_Test_Historikk[Index]

= MAX ( Prognosemodell_Prognose_Total_Test_Historikk[Index] ) - 1)

)

what would actually solve the problem is if i can set the -1 to the index of the min of the chosen months. any idea on how to do this?

You can use Variables in the DAX Measures.

As communicated by tamerj1 , you can cater this scenario.

the reason why i have to use index for this is that i have missing months in between, so the previousmonth etc functions won't work

Hi Anonymous
It depend on the filter context of the visual itself. I can see that all columns are from the same table. Not having dimention tables might be little tricky. The solution I have provided earlier (if the month column is a numeric value column) should work, however, depending on the existing filter context, the filter of some columns might have to be removed. Please provide more context in order to support you further. Thank you.

Yes, but what does that have to do with finding the two selected months? Gaps are irrelevant here.
