Hi
Why we need the fun module
Just write the code as
select-options : s_date for sy-datum no display.
data: date like sy-datum, fdate like sy-datum, tdate is like sy-daum, mon(2),
       mon1(2), mon2(2), year(4).
date =  sy-datum.
year = date+0(4).
mon = date+4(2).
mon1 = mon + 1.
mon2 = mon + 3.
concatenate year mon1 '01' into fdate.
concatenate year mon2 '01' to tdate.
use the fdate and tdate and write the code
