How to use same CMOD code for 2 Diff. variableS?

Question

Experts,
I have written some code under CMOD. Now, i have another query which i could use the same CODE, but diff. variable
( In the CMOD code, i am passing one User input variable ). For the 2nd query i have to pass different User Input variable.
How OR what should i wright to tell CMOD, that IF its Query # 1 then use ABC variable and if Query # 2 then use XYZ .
thanx

Dear Hon Bon,
Let us have a small example on ur scenario.
Lets take the requirement as to calculate Month from Date. (In both the queries).
Query 1: Input variable for Date is say  'ZDATE1'.
Query 2: Input variable for Date is say  'ZDATE2'.
Now let the CMOD variable be ZVAR_CALMONTH.
when 'ZVAR_CALMONTH'.
    clear: lwa_var_rng,
           lwa_range.
    loop at i_t_var_range into lwa_var_rng where vnam = 'ZDATE1' or vnam = 'ZDATE2'.
      concatenate lwa_var_rng-low+0(4)
                  lwa_var_rng-low+4(2)
             into lwa_range-low.
      lwa_range-sign = 'I'.
      lwa_range-opt  = 'EQ'.
      append lwa_range to e_t_range.
      clear lwa_range.
    endloop.
Now when you execute the Query1,  the above code will work for 'ZDATE1' variable,
if you execute the Query2,  the above code will work for 'ZDATE2' variable.
So, the key point is,
1. You need not worry about which query is getting executed. Whatever the query, the particular user entry variable of that query will be taken care.
2. This method works only if the cmod variable (ZVAR_CALMONTH) is used in both the queries (Ofcourse its ur requirement).
3. If queries have both the user entry variables then the cmod will work differently(it ll get data from both the user variables).
You shall try ur code in the above example by replacing the code and the variable names and try playing around it.
Hope this helps.
