Wrong column total

[Silvermountain]

Hi all,

I've stumbled upon a problem that seems to occur regularly. I've found numerous topics that provide information about it, but it might be a topic too many because I didn't manage to find the solution for my particular problem.

I have a couple of columns in my matrix:

• Aantal collectanten, measure: COUNTROWS(contact_role)
• Opbrengst per gebied, measure: sum('col_area_year'[c_amount_realized_revenue])
• Gemiddeld bedrag per collectant, measure:
  CALCULATE(
      if(
  
          and([Opbrengst per gebied]=0,
          [Aantal collectanten]>0),
      55.5,
      DIVIDE([Opbrengst per gebied],[Aantal collectanten])
      )
  )
• Forecast, measure:
  
  CALCULATE(
      if([Opbrengst per gebied]=0, 55.5*[Aantal collectanten],[Gemiddeld bedrag per collectant]*[Aantal collectanten])
  )
  I've also tried the simple way; forecast=[gemiddeld bedrag per collectant]*[aantal collectanten], but with the same result.
  
  
  The column totals in the matrix don't add up. It only does, if the 'gemiddeld bedrag per collectant' is always 55.5 or never 55.5. 
  How can I solve this?

And sometimes you find the solution just 10 minutes later

Nesting the calculate function in a SUMX did the trick.

Forecast =

sumx(col_area,

    CALCULATE(

        if([Opbrengst per gebied]=0, [Waarde van Gemiddelde bedrag per collectant]*[Aantal collectanten],[Gemiddeld bedrag per collectant]*[Aantal collectanten])

    )

)
