Filter issue on runningsum

Hi All,

I have one webi report.In Report ,we are showing percentage of any KF wise for each customer details and after that we are displaying runingsum of that percentage value of each customer in next column.For Each Customer, we have n number of rowcounts.

Requirement is that we have to show only those records whose runingsum is less than 80% rest of the other values should be neglected.

so I applied report filter on calculated runningsum formula, but its incorrect data as runingsum is calculating at runtime.

Can any help me how to resolved this issue.

Thanks in advance.
