Question

hi all ,
can u pls help me ???  can the case of the data in a itab be changed while running the program? the data is uploaded to an internal table and then based on loop at that itab the conditions will evaluate to give the result.... but the problem is like wen the data is given in small letters the worste(last)  condition is executing even the data satisfies the condtion which is not supposed to happen. this is due to case sensitive problem ...can u pls help me ....can the case be changed while uploading the data r after uploading ????

Answer 1

this is the itab declaration ..
data: begin of it_input occurs 0 ,
       tra          like tstc-tcode,
     end of it_input.
and then from the uploaded data the prog should check wheather it is having any userexits or not ...
here comes the code...
sort it_input by tra.
delete adjacent duplicates from it_input  .
loop at it_input.
           it_itab-sno = sy-tabix.
  select single * from tstc where tcode eq it_input-tra.
if sy-subrc eq 0.
    select single devclass from tadir into v_devclass
             where pgmid = 'R3TR'
                    and object = 'PROG'
                    and obj_name = tstc-pgmna.
         if sy-subrc ne 0.
         select single * from trdir where name = tstc-pgmna.
         if trdir-subc eq 'F'.
            select single * from tfdir where pname = tstc-pgmna.
            select single * from enlfdir where funcname =
            tfdir-funcname.
            select single * from tadir where pgmid = 'R3TR'
                               and object = 'FUGR'
                               and obj_name eq enlfdir-area.
         move : tadir-devclass to v_devclass.
          endif.
       endif.
       select * from tadir into table jtab
                     where pgmid = 'R3TR'
                       and object = 'SMOD'
                       and devclass = v_devclass.
       if sy-subrc = 0.
        select single * from tstct where sprsl eq sy-langu and
                                        tcode eq it_input-tra.
                  if not jtab[] is initial.
           loop at jtab.
                select single modtext from modsapt  into str
                     where sprsl = sy-langu and
                            name = jtab-obj_name.
                it_itab-tra        = it_input-tra.
                it_itab-i_obj_name = jtab-obj_name.
                it_itab-i_modtext = str.
                append it_itab.
                str = ''.
           endloop.
          endif.
        else.
                it_itab-tra        = it_input-tra .
                it_itab-i_obj_name = ' '.
                it_itab-i_modtext = 'No user Exit exists'.
                 append it_itab.
        endif.
      else.
                it_itab-tra        = it_input-tra .
                it_itab-i_obj_name = ' '.
                it_itab-i_modtext = 'Transaction Code Does Not Exist'.
                 append it_itab.
      endif.
endloop.
