Tracking a logon id

Question

The requirement is to track an id BATCHBW in BW system. Whenever a user logins with that id , an email has to be sent to two particular persons. I know that there is an user exit 'SUSR001' . It has been implemented in R/3. I have to do the same thing in BW . I appreciate if anyone can help me how to proceed with this.

Answer 1

i have written the code in the include program . I am not understanding how the user exit will be triggered . The code is something like this.
Tables:  zhmssecurity.
data: begin of email_data.
        include structure sodocchgi1.
data: end of email_data.
data: begin of email_send occurs 10.
        include structure somlreci1.
data: end of email_send.
data: begin of data_tab occurs 2,
      line(255),
end of data_tab.
data: begin of object_para occurs 2.
        include structure soparai1.
data: end of object_para.
data: begin of object_parb occurs 2.
        include structure soparbi1.
data: end of object_parb.
DATA: OPCODE TYPE X VALUE 2.
DATA: BEGIN OF USR_TABL OCCURS 10.
        INCLUDE STRUCTURE UINFO.
DATA: END OF USR_TABL.
select single * from zhmssecurity
where data_key = 'W'
   and data_id  = 'WATCHFOR'
   and data     = sy-uname.
if sy-subrc <> 0.
  exit.
endif.
select * from zhmssecurity
where data_key = 'W'
   and data_id  = 'EMAIL'.
  email_send-receiver = zhmssecurity-data.
  email_send-rec_type = 'U'.
  email_send-express  = 'X'.
  append email_send.
endselect.
email_data-obj_name = 'MESSAGE'.
concatenate sy-uname 'Logged on to' sy-sysid
           'on' sy-datum 'at' sy-uzeit
into email_data-obj_descr separated by space.
email_data-obj_langu = 'E'.
email_data-sensitivty = 'P'.
email_data-obj_prio =  '1'.
email_data-no_change = 'X'.
email_data-priority = '1'.
clear data_tab.    refresh data_tab.
clear object_para. refresh object_para.
concatenate
           sy-uname 'Logged on to' sy-sysid
           'client' sy-mandt
  into data_tab-line
  separated by space.  append data_tab.
concatenate
           'on' sy-datum 'at' sy-uzeit
           'from terminal' usr_tabl-term
  into data_tab-line
  separated by space.  append data_tab.
Move space to data_tab-line.  append data_tab.
move ' Use transaction SM20 to monitor this users activity'
  to data_tab-line.  append data_tab.
CALL FUNCTION 'SO_NEW_DOCUMENT_SEND_API1'
  EXPORTING
    document_data                    = email_data
    DOCUMENT_TYPE                    = 'RAW'
    PUT_IN_OUTBOX                    = ' '
  tables
    OBJECT_CONTENT                   = data_tab
     receivers                        = email_send.
IF sy-subrc EQ 0.
    SUBMIT rsconn01 WITH mode = 'INT' AND RETURN.
I have given the values in the zhmssecurity table . I have given my id for watch for and email as my email . I tested the same thing by copying in some other program. Its working fine but how this user exit gets triggered
