Space before and after totals

Hi Experts,

I am developing a Revenue & COGS report. As part of the same, user wants to have Subtotal for Revenue & Expenses accounts and a Total to represent the Gross profit.

He needs one empty row after all Revenue accounts, followed by Total Revenue, then again an empty row ... same for expenses too.  This is dynamic report.

I tried using a local member but when the report is changed, the empty line disappears.

I also tried "EPM function - Insert before and after" but that is also not working... I am also not sure of how to use this function.

Please advise.

Thanks,

Subbu.
