Restrict the values in keyfigure

Hi Experts,

Good day!

I searhed in SCN before posting the thread and could'nt get the exact solution . Is the possible to restrict the data on keyfigure values in BEX level . I have keyfigure which  contains 0 and 1 and would like restrict the data on1  because my requirement in SAP IP if the user able to change the KF so i want to restrict keyfigure value in BEx level.

Regards
