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

[markusb73]

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 ,

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 @v-tangjie-msft ,

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:

Date	Category	Wert
31.12.2008	Value	100
31.12.2009	Value	101
31.12.2010	Value	102
01.03.2009	CF	1
01.06.2009	CF	1
01.09.2009	CF	2
01.03.2010	CF	1
01.06.2010	CF	1
01.09.2010	CF	3

This transforms into CF_Start like

Date	Category	Wert
31.12.2008	Value	-100
31.12.2009	Value	-101
31.12.2010	Value	-102

CF_End like

Date	Category	Wert
31.12.2008	Value	100
31.12.2009	Value	101
31.12.2010	Value	102

and CF_Op like

Date	Category	Wert
01.03.2009	CF	1
01.06.2009	CF	1
01.09.2009	CF	2
01.03.2010	CF	1
01.06.2010	CF	1
01.09.2010	CF	3

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

Date	Category	Wert
31.12.2008	Value	-100
01.03.2009	CF	1
01.06.2009	CF	1
01.09.2009	CF	2
31.12.2009	Value	-102

-->IRR~5%

and

Date	Category	Wert
31.12.2009	Value	-101
01.03.2010	CF	1
01.06.2010	CF	1
01.09.2010	CF	3
31.12.2010	Value	102

-->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

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]))

Dear Neeko, @v-tangjie-msft 

thanks a lot for your help, yes LASTDATE does work now
(like I imagined Selectedvalue should work but did not)

Although I do not really understand why, but this might be due to my low DAX experience and the XIRR complexities.

I however also found out that the XIRR union part also works with simple filter instead of calculate table, see below (the naming is a bit different from the original post)

XIRR Union =

var EndDate = Lastdate('Tab_A _Datums'[DatumS])

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

var Result=Calculate(XIRR(union

    (

    Filter('Tab_A MWS','Tab_A MWS'[Datum]=StartDate),

    Filter('Tab_A CF', 'Tab_A CF'[Datum]>StartDate && 'Tab_A CF'[Datum]<EndDate),

    Filter('Tab_A MWE','Tab_A MWE'[Datum]=EndDate)

    )

    ,[Wert],[Datum]))

    return

    Result

Many thanks,
Markus
