Accumulation in qlik sense with multiple dimensions

[raju_salmon]

Hi Experts,

Can anyone please let me know if there is any way to do accumulation in qlik sense with multiple dimensions.

In a straight table i'm using 3 dimensions. Month, Region and Customer. I want to show the expression [Sum(Sales)] by accumulating 3 steps for month. The accumulation should also work for other 2 dimensions.

For single dimension this expression is working rangesum( above( sum([Expression1]),0,rowno())).

How to write expression to accumulate for multiple dimensions.

Please help me to get the solution. I need this very urgent.

Thanks in advance.

Regards,

Raju
