Operation list in CM21

Hello,

I am using transaction CM21 for capacity leveling. On selection screen I am giving only one workcenter, after execution, in the "orders pool" I can see all the operations in the order but I want to view only operations which allocated to the one workcenter, which I am giving on selection screen.

I tried t codes like CM25 / CM27 all having same results.

What settings I need to do, please guide.
