Accumulative aggregation in a pivot table

[lmenendez_grupo_pinero]

Hi , 

I have a simple pivot table like the image wich has 'show partial sums' ticked in dimension R1.

The first Total (-3.53) is Ok but I would need the following Total was -3,53-0,65=-4,18 and third one was -4,18-0,48=-4,65

Is it easily possible ?

Thanks

Did you solve this? I don't see an image, but typically you use the Above() function in this kind of calculation.
