E-Mailing ERS through T-Code MRRL using a specific E-Mail Address

Question

Hello Everyone:
Wondering if anyone knows a solution to an issue we are coming across.  I tried searching using different terms, but couldn't find an answer.
By default system uses the first e-mail address saved in Vendor Master to e-mail ERS; whereas, we would like to use the 3rd e-mail address (for example) instead.  Is there a BADI, User-Exit, or Enhancement Spot that I can utilize?  Do you know which program, form, function module, etc. MRRL uses to get e-mail address from Vendor Master?
Thanks in advance and if you have any questions, please let me know.
Thanks,

Hi Naveen:
Enhancement can be placed at the end of Form check_comm_type of Include LSZAFF05.  Please see the example below.  In this case, this enhancement is limited only to T-Codes MRRL and MR90.
"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""$"$\SE:(1) Form CHECK_COMM_TYPE, End                                                                                                                         A
*$*$-Start: (1)---------------------------------------------------------------------------------$*$*
enhancement 1  zei_emad4ers.    "active version
** E-Mail Address determination for Evaluated Receipt Settlement (ERS).
   if sy-tcode = 'MRRL' or sy-tcode = 'MR90'.
      read table <lt_comm_table>
           assigning <ls_comm_table>
           index 3.   " Third E-Mail Address stored in Vendor Master
      if sy-subrc <> 0.
         message a890 with 'LT_COMM_TABLE' raising internal_error.
      endif.
      ascf ev_comm_values ls_comtypes-table_type <ls_comm_value>.
      <ls_comm_value> = <ls_comm_table>.
      ev_comm_type = cs_strategy-comm_type.
      cs_strategy-status = 'F'.
   endif.
endenhancement.

Hope this helps, but if you have any questions, please let me know.
