Compounding Table

[Anonymous]

Hi All,

This might be one of those things that is possible in excel, but not QlikView. We have a report that we manually do in excel that essentially calculates Churn (a loss of revenues).  However, we do this compounding.  So if we lose the revenues in January, we also will show that those revenues are lost in February, March, etc. 

Can this be done in a table or pivot table?  Can I turn this:

Into this:

Maybe an accumulation approach should fit your need then?

Maybe just something like

= Rangesum( Before( Sum(ChurnField),0, ColumnNo() ))

Thats awesome! Thanks!  Can this be done with set analysis?  Below is the formula that I was using.

SUM({$<Won_Flag={1}, ChurnYear = {'2016'}>}[Churn MRR])

I'd also like to know if there is a way to guarantee the months as headers.  While highly unlikely, there's no guarantee that we'll have churn in any particular month. Though I think that might be for another thread.

It should work with just replacing my sum(ChurnField) with your expression (sum with set analysis).

I would suggest opening another thread for your second question (or search the forum, there are some threads available that are coping with this kind of issue).
