How to suppress values in OVS

Hello Gurus,

I have a requirement to suppress certain sales territories which start with a string, lets say "Country-".

So, the result set should not show entries like "Country-USA", "Country-Mexico".

I tried in the Select options as seen below. But it does not help.

If I want to show only those which start with Country-, I changed the select option to Include and it works.

Any help is appreciated.

thanks
