User exit on User entered Variable

Question

Is it possible to run a user exit that will filter for a particular date, based on what the user enters. For example if the user enters the day May 20, 2008. Can instead filter the report for May 18, 2008 (Always Sunday). How do I go about doing this? I have the code to find the Sunday date, just having difficulty getting it to executing after the user has entered a date.

Hi Vendant
You will need 2 variables, the one the user enters the date against and another customer exit variable executed in step 2 that takes the input date and returns it to sunday.
This CMOD code might help, you may need to tweek it to cater to the date format you use
CASE i_step.
WHEN 2.
CASE i_vnam.
WHEN 'Tech name of customer exit var'.
DATA: loc_var_range LIKE rrrangeexit,
l_s_range TYPE rrrangesid.
DATA: i_t_var_rec LIKE LINE OF i_t_var_range.
DATA: l_text(10) Type C.
READ TABLE i_t_var_range INTO loc_var_range
WITH KEY vnam = 'tech name of first date var'.
use your code to find sunday here on the loc_var_range-low, this is the value the user entered.
you will need to assign loc_var_range-low to a variable like l_text as you cant manipulate it directly
l_text = loc_var_range-low.
l_s_range-low = the result of your find sunday code.
l_s_range-high = ''.
l_s_range-sign = 'I'.
l_s_range-opt = 'EQ'.
APPEND l_s_range TO e_t_range.
ENDCASE.
ENDCASE.
Hope this helps
