Help with XIRR, SELECTEDVALUE and Matrix table with multiple columns values

Hello, I am having problems to show XIRRs for a set of multiple dates with SELECTEDVALUE.

The same IRR calculation for any single date however works fine!

 

The code is as follow:

XIRR Yearly with Selectedvalue =

var EndDate = SELECTEDVALUE('Tab_SelectedDates'[DateS]) //e.g. 2019/12/31 & 2020/12/31

var StartDate = Date(year(EndDate)-1,12,31) // ->2018/12/31 & 2019/12/31

 

var CF_Start=CALCULATETABLE('Tab_StartValues','Tab_StartValues'[Date]=StartDate)

var CF_Op=CALCULATETABLE('Tab_CFValues', 'Tab_CFValues'[Date]>StartDate && 'Tab_CFValues'[Date]<EndDate)

var CF_End=CALCULATETABLE('Tab_EndValues','Tab_EndValues'[Date]=EndDate)

var CF_Union=CALCULATETABLE(union(CF_Start,CF_Op,CF_End)) //Combining all three CF segments Start,Op&End

 

var IRR= CALCULATE(XIRR(CF_Union,[Wert],[Date]))
//Calculating  IRR (not working for multiple DateS values, but works correct with any single DateS values)

var AVG_VALUES=CALCULATE(Average([Wert]))
//This alternative calulation of Average instead of IRR works perfectly for multiple DateS!?

    return

    IRR

 

In the Matrix table with DateS as columns and the measure as values  I would expect something like

2019-31-12

2020-31-12

5%

6%

 

However there is an error message for the matrix table

Can’t display the visual

Details: Couldn’t load the data for this visual
MdxScript(Model)(39,20) Calcuclation error in measure XIRR Yearly
A result for XIRR couldn’t be determined because the Values and Dates arguments are empty.

 

But if I filter to a single date with a slicer, the same matrix table calculates correctly 5% and 6% for each single filtered date.

So in principle the XIRR in the matrix table works fine for a single filtered DateS (and the underlying data is fine)

But it does not work with multiple DateS in the columns.
It must be a specific issue with the XIRR function, because if I use any other simpler function like Average ([Wert]) it all works, i.e. showing the average for multiple DateS columns.

Any suggestions? I am wondering if the filtering is causing the XIRR formula issues?

    Hi markusb73 ,

     

    Try it:

    XIRR Yearly with Selectedvalue =

var EndDate = LASTDATE('Tab_SelectedDates'[DateS]) 

var StartDate = Date(year(EndDate)-1,12,31) 
 

var CF_Start=CALCULATETABLE('Tab_StartValues','Tab_StartValues'[Date]=StartDate)

var CF_Op=CALCULATETABLE('Tab_CFValues', 'Tab_CFValues'[Date]>StartDate && 'Tab_CFValues'[Date]<EndDate)

var CF_End=CALCULATETABLE('Tab_EndValues','Tab_EndValues'[Date]=EndDate)

var CF_Union=CALCULATETABLE(union(CF_Start,CF_Op,CF_End)) 

var IRR= CALCULATE(XIRR(CF_Union,[Wert],[Date]))

    Hi markusb73 ,

     

    It seems like the issue might be related to the fact that the XIRR function requires two arguments: an array of cash flows and an array of dates. In your code, you are using the CALCULATETABLE function to create tables for the cash flows and dates, but it's possible that the SELECTEDVALUE function is not returning the expected values for the dates when multiple dates are selected. One suggestion would be to use the VALUES function instead of SELECTEDVALUE to get a list of all the selected dates, and then use that list to create the table of dates for the XIRR function. You could try something like this: 

     

     

    ``` var SelectedDates = VALUES('Tab_SelectedDates'[DateS]) 
var DatesTable = FILTER('Tab_CFValues', 'Tab_CFValues'[Date] IN SelectedDates) 
var CF_Union = UNION('Tab_StartValues', DatesTable, 'Tab_EndValues') 
var IRR = XIRR(CF_Union, [Wert], [Date]) ```

      Dear Neeko Anonymous ,

      many thanks for you idea, however I think it does not apply/work in this case.

       

      Lets explain by the data, e.g. the base data as follows:

      DateCategoryWert
      31.12.2008Value100
      31.12.2009Value101
      31.12.2010Value102
      01.03.2009CF1
      01.06.2009CF1
      01.09.2009CF2
      01.03.2010CF1
      01.06.2010CF1
      01.09.2010CF3

       

      This transforms into CF_Start like

      DateCategoryWert
      31.12.2008Value-100
      31.12.2009Value-101
      31.12.2010Value-102

       

      CF_End like

      DateCategoryWert
      31.12.2008Value100
      31.12.2009Value101
      31.12.2010Value102

       

      and CF_Op like

      DateCategoryWert
      01.03.2009CF1
      01.06.2009CF1
      01.09.2009CF2
      01.03.2010CF1
      01.06.2010CF1
      01.09.2010CF3

       

      The to be calculated Cashflows for the 1 year IRRs for the End_Dates 2019/12/31 & 2020/12/31 using union are therefore:

      DateCategoryWert
      31.12.2008Value-100
      01.03.2009CF1
      01.06.2009CF1
      01.09.2009CF2
      31.12.2009Value-102

      -->IRR~5%

      and

      DateCategoryWert
      31.12.2009Value-101
      01.03.2010CF1
      01.06.2010CF1
      01.09.2010CF3
      31.12.2010Value102

      -->IRR~6%

       

      And for a single filtered end date the calculation works fine, but not for multiple i.e.>=2 selectedvalue dates in a matrix table

      Regarding your suggestion:

      The due dates=end dates for the IRRs to be calculated are not the same as the relevant CF_Op dates.
      The CF_Op dates are >StartDate and <EndDate and are actually 3 dates in this example, and not identical to the selected end dates

       

      Maybe the issue is the double filter condition in
      var CF_Op=CALCULATETABLE('Tab_CFValues', 'Tab_CFValues'[Date]>StartDate && 'Tab_CFValues'[Date]<EndDate)
      combined with XIRR & union

      and you approach using IN Relevant_dates would work, but I have not figured out how to do this in this context.

      But many thanks for your suggestion.

      Kind regards,
      Markus
