Inner Joins & for all entries

Question

Hi
1) SELECT RSEGBUKRS RSEGBELNR RSEGGJAHR RSEGBUZEI RBKPLIFNR RSEGWERKS RSEGEBELN RSEGEBELP RSEGMATNR RSEGWRBTR RBKPRBSTAT RBKPZUONR RBKPRMWWR RBKPWAERS RBKP~KURSF
          INTO TABLE I_RSEG
           FROM RBKP
           INNER JOIN RSEG
           ON
           RBKPBELNR = RSEGBELNR AND
           RBKPGJAHR = RSEGGJAHR
           FOR ALL ENTRIES IN I_BKPF
           WHERE RBKP~BELNR = I_BKPF-BELNR
             AND RBKP~GJAHR = I_BKPF-GJAHR
             AND RSEG~WERKS IN S_WERKS
             AND RBKP~LIFNR IN S_LIFNR.
2) IF NOT I_BKPF[] IS INITIAL.
   SELECT belnr gjahr lifnr rbstat zuonr rmwwr waers kursf stblg
                    FROM rbkp into corresponding fields of table i_rbkp1
                       FOR ALL ENTRIES IN I_BKPF
                       WHERE BELNR = I_BKPF-BELNR
                       AND   GJAHR = I_BKPF-GJAHR
                       AND   LIFNR = S_LIFNR.
ENDIF.
   I am replacing the first select statment using inner join with for all entries. but it is not yelding same result.First select statement retrieves records while second one does not using same where conditions. How inner join would work,can we replace inner join using for all entries.
