Filter after grouping

Hi,

Is there a way to SUM only those group results, whose value is greater than 0.

For e.g. I have date filter in my power BI

When I am selecting date range, Winners in that range get selected whose combined PnL for those days is greater than 0.

Now I want to SUM up winners only (i.e. Only those Clients who were actually winners, during those time period).

**Note : If I put Filter PnL in detail level, it will not work. I must SUM UP before applying filters. 

I tried to put below condition but no luck

Test Sum = CALCULATE(SUM(EnhacedHeracles[Gross Revnue]),FILTER(GROUPBY(EnhacedHeracles,EnhacedHeracles[ClientName]),SUM(EnhacedHeracles[Gross Revnue]) >0))

Any help will be greatly appreciated !! 

Reagards,
