Hi Sarabjit,
This is very simple..
But the place where you add this code matters. You can not add this to INITIALIZATION event as the user will change the value after this..
You cannot add this code to AT SELECTION-SCREEN events too.. as the user can execute them by pressing enter and then again can change the value.
You can add this code in START-OF-SELECTION event.
If your select option is s_date. A select option is an internal table. It has a sturcture as below:
Sign --> 1 Character --> I (Include), E(Exclude)
Option --> 2 Character --> EQ, BT, NE, LT, GT etc..
low --> Low value  --> 8 char in this case
High --> High Value --> 8 char in this case
So, at the run time, you will have a record as:
I BT 20070827 20070831
Now, you want that the high value should be 1 day before..
Code like this..
IF NOT s_date[] IS INITIAL.
LOOP AT s_date.
IF NOT s_date-high IS INITIAL.
s_date-high = s_date-high - 1.
MODIFY s_date.
ENDIF.
ENDLOOP.
ENDIF.
