You can make use the belowsaid code for identifying user exits pertaining to any transaction.
Source Code to find User Exits 1
* REPORT YSMOD2
* SELECTION TEXTS : INPUT1 ----> Enter search term for Trxn.
*                   INPUT2 ----> Enter type of exit
REPORT YSMOD2 .
TABLES: MODSAP, MODACT, TSTC.
PARAMETERS: INPUT1 LIKE TSTC-TCODE DEFAULT ' ',
            INPUT2 LIKE MODSAP-TYP DEFAULT ' '.
DATA: SEARCH1(6),
      SEARCH2(3),
      SEARCH3 LIKE MODSAP-MEMBER.
DATA : FIRST_ROW VALUE 'Y'.
CONCATENATE: '%' INPUT1 '%' INTO SEARCH1,
             '%' INPUT2     INTO SEARCH2.
SELECT * FROM TSTC WHERE TCODE LIKE SEARCH1.
  FIRST_ROW = 'Y'.
  CHECK TSTC-PGMNA NE SPACE.
  CONCATENATE '%' TSTC-PGMNA '%' INTO SEARCH3.
  SELECT * FROM MODSAP WHERE TYP LIKE SEARCH2
                       AND MEMBER LIKE SEARCH3.
    SELECT SINGLE * FROM MODACT WHERE MEMBER = MODSAP-NAME.
    IF FIRST_ROW EQ 'Y'.
      WRITE: /0 TSTC-TCODE, 6 TSTC-PGMNA, 16 MODSAP-NAME, 32 MODSAP-TYP,
                                       45 MODSAP-MEMBER, 70 MODACT-NAME.
      FIRST_ROW = 'N'.
    ELSE.

    ENDIF.
