In a cutomer Exit Variable how to consider other variable value at Runtime.

[anju_naidu]

Scenario:

The are some case when creating a customer exit variable we need to consider other variable value at run time.

Requirement:

Create a FI-AR or FI-AP aging report . In which we need to create aging buckets . We consider Posting Date , Document Date  and Cleared Dates to calculate

Balances.Our requirement to consider Document date value which calculating clearing date and posting date.

step 1 :

Create a variable for Document date calculation.

code :

data: v_date      type sy-datum,
         v_qtr(2)    type c,
         wa          like LINE OF i_t_var_range,
         l_s_range   like line of e_t_range,
         v_day    type n length 2,
         v_year    type n length 4,
         p_year    type n length 4,
         l_vnam    TYPE rszglobv-vnam.

   constants: c_varname type rszvnam value 'ZVAR_DOC_DATET',
              c_iobjnm  type rsiobjnm value '0DOC_DATE'.

   if i_step = 0 or i_step = 1.



l_vnam = i_vnam.

   IF l_vnam = 'ZVAR_DOC_DATET'.
*Read System Date
     l_s_range-low = sy-datum.
     l_s_range-sign     = 'I'.
     l_s_range-opt      = 'EQ'.
     APPEND l_s_range TO e_t_range.
endif.
endif.

*}   INSERT
ENDFUNCTION.

step 2 :

: Call the Document date variable value into clearing date calculation ( The FM also created exactly in same manner).

              user the same parameters like 'Z_*_ZVAR_DOC_DATET'.

           code :

data: wa          like LINE OF i_t_var_range,
         l_s_range   like line of e_t_range,
         l_vnam    TYPE rszglobv-vnam.

   constants: c_varname type rszvnam value 'ZVAR_DOC_DATET',
              c_iobjnm  type rsiobjnm value '0DOC_DATE'.

   if i_step = 1.
     clear: l_s_range.
      l_vnam = i_vnam.

   IF l_vnam = 'ZVAR_CLEAR_DATE3'.
* Read the variable ZVAR_DOC_DATET value.
     loop at i_t_var_range into wa
           where vnam = c_varname
             and iobjnm = c_iobjnm.
     endloop.

         if sy-subrc = 0.
              l_s_range-low = wa-low.
              l_s_range-sign     = 'I'.
              l_s_range-opt      = 'EQ'.
              APPEND l_s_range TO e_t_range.
         endif.
    endif.

elseif  i_step = 0.

              l_s_range-low = sy-datum.
              l_s_range-sign     = 'I'.
              l_s_range-opt      = 'EQ'.
              APPEND l_s_range TO e_t_range.
ENDIF.

*}   INSERT
ENDFUNCTION.

In this we call the value of variable 'ZVAR_DOC_DATET'  into a loop over.And used that value into our required variable .

Note : Make sure   'RSR00001 BI: Enhancements for Global Variables in Reporting' is developed in a way to support variable call as Function module.

we can  also use the same approach  in our traditional variable calculation also.

Hope this Helps!
