Question

hi experts, i have written the following query.
     SELECT BUKRS BLART BUDAT BLDAT MONAT
             FROM BKPF INTO CORRESPONDING FIELDS OF TABLE IT_BKPF
                 WHERE BUKRS IN BKRS AND BUDAT IN DATE.
       IF SY-SUBRC EQ 0.
       SELECT BUKRS BELNR GJAHR DMBTR PSWSL ZUONR SGTXT AUFNR ALTKT SHKZG HKONT
          FROM BSEG INTO CORRESPONDING FIELDS OF TABLE IT_BSEG FOR ALL ENTRIES IN IT_BKPF
             WHERE BUKRS = IT_BKPF-BUKRS AND BELNR IN DOC AND HKONT IN GLE.
         IF SY-SUBRC EQ 0.
           SELECT BUKRS KTEXT FROM AUFK INTO CORRESPONDING FIELDS OF TABLE IT_AUFK
              FOR ALL ENTRIES IN IT_BKPF WHERE BUKRS = IT_BKPF-BUKRS.
             SELECT TXT50 TXT20 FROM SKAT INTO CORRESPONDING FIELDS OF TABLE IT_SKAT
             FOR ALL ENTRIES IN IT_BSEG WHERE SAKNR = IT_BSEG-ALTKT.
               ENDIF.
               ENDIF.
and transfering tha data into final table like this
IT_FINAL[] = IT_BKPF[].
LOOP AT IT_FINAL.
   READ TABLE IT_BSEG WITH KEY BUKRS = IT_FINAL-BUKRS.
   IF SY-SUBRC EQ 0.
  MOVE-CORRESPONDING IT_BSEG TO IT_FINAL.
   IT_FINAL-BELNR = IT_BSEG-BELNR.
   IT_FINAL-GJAHR = IT_BSEG-GJAHR.
   IT_FINAL-DMBTR = IT_BSEG-DMBTR.
   IT_FINAL-PSWSL = IT_BSEG-PSWSL.
   IT_FINAL-ZUONR = IT_BSEG-ZUONR.
   IT_FINAL-SGTXT = IT_BSEG-SGTXT.
   IT_FINAL-AUFNR = IT_BSEG-AUFNR.
   IT_FINAL-SHKZG = IT_BSEG-SHKZG.
   IT_FINAL-HKONT = IT_BSEG-HKONT.
   IT_FINAL-ALTKT = IT_BSEG-ALTKT.
     ENDIF.
     APPEND IT_FINAL.
   ENDLOOP.
   LOOP AT IT_FINAL.
     READ TABLE IT_AUFK WITH KEY BUKRS = IT_FINAL-BUKRS.
         IF SY-SUBRC EQ 0.
           IT_FINAL-KTEXT = IT_AUFK-KTEXT.
           ENDIF.
           APPEND IT_FINAL.
  ENDLOOP.
  LOOP AT IT_FINAL.
    READ TABLE IT_SKAT WITH KEY SAKNR = IT_FINAL-ALTKT.
     IF SY-SUBRC EQ 0.
       IT_FINAL-TXT50 = IT_SKAT-TXT50.
       IT_FINAL-TXT20 = IT_SKAT-TXT20.
       ENDIF.
       APPEND IT_FINAL.
  ENDLOOP.
i am getting an runtime error'the system is configured incorrectly' even for the value of bukrs between 0001& 0005 and for budat 28.08.2006 & 28.05.2009.
what happened?
the current program had to be terminated because of an error when installing the R/3 system.
the program had already reuested 399201216 bytes from the operating system with 'malloc' when the OS reported after a further memory request that there was no more memory space available.
plz help....is there any problem in my query or do i need to change something from logic?
thnks n regards,
Ashmita

Hi Ashmita,
1. Whenever we use FOR ALL ENTRIES, we should check the content of the main table.
   BCOS if it empty, then ALL records will be fetched (in this case, from BSEG).
2. When just put a IF condition
if  IT_BKPF[] is not initial.
select..... from BSEG... for all entries.....
endif.
3. This error may be coming because many many records are getting selected from BSEG and the memory on server is not available. Hence, one option is you may restrict your search. But before that please make sure the above check is in place.
(You have already used if sy-subrc = 0, that may also work, but better to use the above)
regards,
amit m.
