TOTALYTD error

[DickyMoo]

Hi everyone,

I am using the below measures:

Sum of Amount - Actuals = CALCULATE( SUM(SUN[Amount]) , SUN[Ledger] = "A" )

YTD Actuals = IF( HASONEVALUE( 'Calendar'[Financial Year] ) , TOTALYTD( [Sum of Amount - Actuals] , 'Calendar'[Date] , "30/06" ) , 0 )

Pretty standard stuff.

However, I get some unusual behaviour when drilling through charts.

Our structure goes Department > Cost Centre. Everything is as expected at Department level, but when I drill to Cost Centre level some values are missing. Upon investigation the missing values are those that do not have a value in the month selected by slicer. But for those that do have a value in the current month, the values are summing correctly for the YTD.

If I select all months up to and inc. current month the problem is fixed, but this is not how I would like people to use the report.

Any ideas? Do I need to change my YTD measure to include FILTER(ALL(Dates ... ?

Thanks
Rich

i've had to add extra values of zero for each expected value, so I never have a null (and therefore the tables populate properly)

Do you mean add these lines to the source data? I'm pulling from a SQL database so I'm not sure how to do that.

-- I should also have said above that the totals are correct, its just the individual Cost Centre lines that are wrong.

i run some vba after the sql and add all the static ID and a value of zero, so if in a small data set it isn't available my zeros help the consistent modelling

Ok, I might look at that as a longer term solution, something to add to the DW. Thank you.

I am getting the correct results with the below, but I'm confused, I thought TOTALYTD did the equivalent of this anyway...?

YTD Actuals TEST = CALCULATE([Sum of Amount - Actuals], FILTER(ALL('Calendar') , AND('Calendar'[Financial Year] = 2016 , 'Calendar'[Financial Month] <= 3) ) )

Is the problem that with my first measure I'm filtering down to only those rows that have data in the current month (because of the month selected on the slicer) then applying the TOTALYTD to that filtered list???

probably, but without playing with i'm not sure, if there is nothing to model. I'm familiar with pivots not powerBI

After reading this:

Bidirectional cross-filtering whitepaper | Kasper de Jonge Microsoft BI Blog

I discovered what the problem was. I had set the relationship between my Fact and Calendar tables as both directions, so the month slicer was filtering the Calendar table to only those Cost Centres with transactions in the current month, therefore not allowing the TOTALYTD to work correctly.

Lesson learned.
