Filter by a measure

Hi folks, I have one table with 2 measures

"Total Revenues" , "Total Budget"

I have a 3rd measure that prints "OK" if the first 2 columns have the same value otherwise prints "KO" if Total Revenues" <> "Total Budget". 

Works fine, but I can't insert a Slicer Filter to filter only rows with "OK" (or "KO") values

Any suggestion is appreciated.

Thanks,
