Hi,
In pivot table, I have the following table :
date 1 date 2 date 3 ....
initial_value $100 ??? ???
movement 1 $200 $50
movement 3 -$100 -$100
grand total $200
I would like to do that the value for initial column date 2 (and date 3, etc) would be equal to grand total column left.
For column date2 the value would be: $200.
For column date3 the value would be: $150.
It's a calculated value (it is a balance).
* for movement "initial value" of column j => value !=0 ? initial_value: grand total of column (j-1).
Is there any way to do this calculation ?.
I see examples of fields calculated in the documentation but differing from my needs.
Thanks in advance.
Jorge
