Customer Exit Logic

Question

Dear All,
First, Let me say Thanks to the SDN Community which always helping me in improving my competency and solving issues.
Here, I have a report which takes Calendar month as input, Based on the given month report has to calculate whether the given month is in the 1st half of the year or 2nd half of the year. If the month falls into 1st half, then the report has to display the entire year's data. if the month falls into the 2nd half, then the report has to show 2nd half of the entered year and the 1st half of the next year.
I tried it by creating 2 variables 1 is on calmonth with options user entry/Default value, mandatory, Single value and the second one is on calyear with options Customer exit,Mandatory,interval. in the exit I used
I-step =2. but the report is displaying values for the entered month only.
Can you guys please throw a light on how to achieve this?
Thanks and Regards

Hi.
You need to use an exit variable that is an interval on 0calmonth, not 0calyear, because with 0calyear, you can't define "last half of this year and first half of next year".
So you exit logic should be something like the below (cant remember if 'concatenate' works like that...).
Also, since you are restricting on 0calmonth to let the user make a choice, you will need to put the 0calmonth infoobject somewhere in your query. Since you need a column for your "dynamic" interval, you will need to put the single month restriction on 0calmonth in it's own restricted key figure and then hide it.

data:
Month(2) type n,
lv_year type 0calyear,
lv_from type 0calmonth,
lv_to type 0calmonth.
when 'ZMONTHINT'.
if i_step = '2'.
Loop at I_T_VAR_RANGE INTO LOC_VAR_RANGE where VNAM = 'ZUSICALM'.
clear l_s_range.
lv_year = loc_var_range-low+0(4).
Month = loc_var_range-low+4(2).
if Month <= 06.
concatenate lv_year '01' into lv_from.
concatenate lv_year '12' into lv_to.
l_s_range-low = lv_from.
l_s_range-high = lv_to.
l_s_range-sign = 'I'.
l_s_range-opt = 'BT'.
APPEND l_s_range TO e_t_range.
else.
concatenate lv_year '07' into lv_from.
lv_year = lv_year + 1.
concatenate lv_year '06' into lv_to.
l_s_range-low = lv_from.
l_s_range-high = lv_to.
l_s_range-sign = 'I'.
l_s_range-opt = 'BT'.
APPEND l_s_range TO e_t_range.
endif.
endloop.
endif.
endwhen.
