To find out appropriate user exit/ badi for transaction VT01n

Question

Hi,
   I have the following requirement.
Cass shipment type (VTTK-ADD03) field needs to be required and should be automatically populated upon creation of the shipment document.  The rules for populating the value (SO, ST, PO and RA) are as follows:
If any of the orders on the shipment are customer order types, then the CASS shipment type should be a SO,
If all of the orders are STO orders, then the Cass shipment type should be "ST",
If all of the orders are PO orders, then the Cass shipment type should be "PO" , and
If all of the orders are customer return orders, then the Cass shipment type should be "RA".
I have to find out proper user exit / badi to do this.I have tried with many userexit but it won't work.
   Thanking in advance to give your suggestion in order to resolve it.
With regards,
Ajit.

Hi this code will enable you to find the user exit for any transaction . Just give the transaction as input
tables : tstc, tadir, modsapt, modact, trdir, tfdir, enlfdir.
         tables : tstct.
data : jtab like tadir occurs 0 with header line.
data : field1(30).
data : v_devclass like tadir-devclass.
parameters : p_tcode like tstc-tcode obligatory.
select single * from tstc where tcode eq p_tcode.
if sy-subrc eq 0.
   select single * from tadir where pgmid = 'R3TR'
                    and object = 'PROG'
                    and obj_name = tstc-pgmna.
   move : tadir-devclass to v_devclass.
      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.
        select single * from tstct where sprsl eq sy-langu and
                                         tcode eq p_tcode.
        format color col_positive intensified off.
        write:/(19) 'Transaction Code - ',
             20(20) p_tcode,
             45(50) tstct-ttext.
                    skip.
        if not jtab[] is initial.
           write:/(95) sy-uline.
           format color col_heading intensified on.
           write:/1 sy-vline,
                  2 'Exit Name',
                 21 sy-vline ,
                 22 'Description',
                 95 sy-vline.
           write:/(95) sy-uline.
           loop at jtab.
              select single * from modsapt
                     where sprsl = sy-langu and
                            name = jtab-obj_name.
                   format color col_normal intensified off.
                   write:/1 sy-vline,
                          2 jtab-obj_name hotspot on,
                         21 sy-vline ,
                         22 modsapt-modtext,
                         95 sy-vline.
           endloop.
           write:/(95) sy-uline.
           describe table jtab.
           skip.
           format color col_total intensified on.
           write:/ 'No of Exits:' , sy-tfill.
        else.
           format color col_negative intensified on.
           write:/(95) 'No User Exit exists'.
        endif.
      else.
          format color col_negative intensified on.
          write:/(95) 'Transaction Code Does Not Exist'.
      endif.
at line-selection.
   get cursor field field1.
   check field1(4) eq 'JTAB'.
   set parameter id 'MON' field sy-lisel+1(10).
   call transaction 'SMOD' and skip first   screen.
