"Excluding" not working with PF status In ALV tool bar

Hi all,

I have 5 buttond in ALV tool bar out of which for every distinct logic only two buttons should be actually visible on toolbar.For this am using-

SET PF-STATUS 'ZQACCAL' EXCLUDING '&QE17''&QA13''&QE19' IMMEDIATELY.

Problem is am still viewing excluded buttons (ie '&QE17''&QA13''&QE19' )also.

Please tell me the solution for the same.

Thank you.
