less than one day

Hi all,

I want date like posting date should be system date -1.

I am doifn like this.

select-options : s_budat for rbkp-budat.

loop at s_budat.

s_budat-sign = 'I'.

s_budat-option = 'Eq'.

s_budat-low = w_date - 1.

append s_budat.

endloop.

from above result I am not getting the less than one day of sys date.

But every time I want less than oneday of sys date.

I need to work with Range table only not parameters.

thanks for your help.
