Dear All,
Quick question on Set Analysis. I'm struggling to think and I need some help.
I'm trying to use the Variable in Set Analysis which contains below expression :
ONLY(ID)
And my Set Analysis Expression is :
=SUM({$<Part = {">$(=($(vTest)))"} >} MyCount)
And this is returning 0 instead it should return same values as [Matching Output] column - (Please see attached example).
I already achieved the final result in [Matching Ouput] field but when the users select the [Part] field then my numbers change and I don't them to change but there should be selection on the chart/table. That's reason I'm using the Set Analysis approach instead of using Above() and RangeSum() functions.
I hope this makes sense.
Thanks in advance.
Cheers,
DV
Hi DV,
it seems to me that you are trying to create a set expression that will evaluate the ID in the context of the current line, and I believe this will not work. The set expression will be evaluate once per chart (I think you can actually see the expression used when using <use expression> as label and then hover over the label in your chart column).
There are methods to use a pick / match combination to simulate an evaluation per current dimension value (by creating in fact a set expression per line), check out the discussion thread here)
Coming back to your original request, if I understood correctly, you can achieve what you want by embedding your working expression (with an appropriate set expression added) in an advanced aggregation, like
=aggr(SUM({1}TOTAL MyCount) - RangeSum(Above(sum({1}MyCount),1,RowNo()) ),Part)

Thanks Stefan.
This makes sense. I keep forgetting about Set Analysis behaviour and end-up wasting my time.
Many thanks again.

Thanks to both of you, to Mr. DV for asking such a question and to Mr. Swuehl a wonderful answer and for such a nice thread.
One of my senior Mr. Anil (user name: anilsknp) me about both of you that some time Mr. DV and alot of time Mr. Swuehl : Stefan help him.
Very nice and logical explanation Mr. Stefan headsoff to you.
DV can you please explain in a very simple way again that "How to ask a question in community"
thanks & regards

indianqvlover - I'm glad to know that you have learnt something new. Thanks to Stefan.
Stefan - I have decided to use Pick/Match approach along with Concat() & ValueLoop() functions to generate the expression based on Dimension. Thank you for all your help.
