Hi Raj,
You can do this by creating a Login screen for the users and check the authentication of each user in PAI i.e. PROCESS AFTER INPUT.
Store the user information in a database table and check the username and password when the user enters it.
You can display password as *** also. For this double click on input box designed for password and goto Display tab. Select Invisible in the list and check it.
  CASE sy-ucomm.
    WHEN 'BACK'.
      LEAVE PROGRAM.
    WHEN <fcode for submit>.
      SELECT SINGLE uname pwd
       FROM <DB table>
       INTO (user, pass)
       WHERE username = user AND
               password = passwd.
      IF sy-subrc = 0.
<Go to next screen for further processing>
      ELSE.
<Display Error message and exit>
      ENDIF.
  ENDCASE.
Regards,
Amit
