Need help with Pivot ! Different totals for each level !

Hello colleagues.

I have one interesting task for you

I'll try to explain my situation...

I have one fact table with simple structure: Date, Item, Flag

And one master data table - Item, with structure like this: Item, Group.

In fact table for each Item and date I have Flag 1 or 0.

And I need calculate number of Dates, where Flag is 0.

I have a simple pivot chart with 2 dimensions: Group and Item. And I need to calculate count of Dates, where Flag = 0.

For each Item it is a very simple, I use such expression: count({<Flag = {0}>} Date)

pic2.png

But for Group level I get sum of count Dates, but I need count Dates, where Flags of all items from this group is 0.

pic3.png

In another words, I need to get a number of Dates where subtotal (for each group) is 0.

So as a Result I want to get for

G1 is 1 (because there is only one Date, where flags for all Items are 0)

G2 is 4.

Does anyone have any ideas?

Thanks a lot.

No ideas?

I'm ready to use any crazy ideas, which could help to achieve the final result.

The result is definetly right.  This way set analisys is working.

You case is completely different, try something like this:

=if(Dimensionality()=1,

Sum(aggr(if(Sum(Flag)=0, count(Date), null()), Group, Date)),

Sum(aggr(if(Sum(Flag)=0, count(Date), null()), Group, Item, Date)))

Hi,

Same here! I tried aggr, if, mixing if with aggr with no succes.

Did you thought to a different approach? See the file attached.

Regards,

David

2 whiteline: yeah, your approach is working. I thought about Dimensionlity too, but I try to avoid such huge numbers of IF statements.

but anyway, thanks a lot. Your variant is the best until now.

2 daveamz01: thanks a lot, but your approach is not flexible, for instance, if I add Item as a second dimension, your approach doesn't work.

2 all: Does anybode have any ideas else?

To make it flexilbe use: if(Dimensionality()=1,count({<FlagS={0}>}Date2),count({<Flag = {0}>}Date))

Thanks  daveamz01

your approach is working too. but it uses dimensionality() function too.

and I hope that we can achieve results without pre-calculation (in script level)

may be, very very strong and complex AGGR or something else

I need to get a number of Dates where subtotal (for each group) is 0.

I think you just can't do it the way you want.

The subtotals for each level has different meaning in your case.
