"Display As Running Sum" Feature

Question

Hi
Tried to use "Display As Running Sum" feature and it looks like it adds all the values across the pivot table and does not reset it on a new row...
So for instance we ahve a table as follows
A 1 2
A1 3 4
A2 5 6
After running sum applied:
A 1 3
A1 6 10
A2 15 21
Is there any way value could be reset after each row ? Any hidden configuration file to be changed ?

Answer 1

Initial data is:
Product Date Value
A Day1 1
A Day2 2
A Day3 3
A1 Day1 4
A1 Day2 5
A1 Day3 6
A2 Day1 7
A2 Day2 8
A2 Day3 9
Pivot table looks like:
---- Day001 Day002 Day003
A 1 2 3
A1 4 5 6
A2 7 8 9
Required table (values disaplyed as running sums by product)
---- Day001 Day002 Day003
A 1 3 6
A1 4 9 15
A2 7 15 24
PROBLEM: its easy to create formula RSUM(value by product) and put it as pivot table measure BUT I have around 1000 reports with different dimensions which requires to create RSUM(value by dimension1), RSUM(value by dimension2) ... RSUM(value by dimension1000) and its sort of nightmare...
Instead of RSUM I thought that feature "Display As Running Sum" could be used, but its not working as expected in terms of it does not get reset for each row. How do I configure "Display As Running Sum" to reset value for each row ?
PS: this is what "Display As Running Sum" gives
---- Day001 Day002 Day003
A 1 3 6
A1 10 15 21
A2 28 36 45
