Performance issue with the Select query

Question

Hi,
I have an issue with the performance with a seclet query.
In table AFRU - AUFNR is not a key field.
So i had selected the low and high values into s_reuck and used it in Where condition.
Still i have an issue with the Performance.
SELECT SINGLE RUECK
RMZHL
IEDD
AUFNR
STOKZ
STZHL
FROM AFRU INTO table t_AFRU
FOR ALL ENTRIES IN T_ZSCPRT100
WHERE RUECK IN S_RUECK AND
AUFNR = T_ZSCPRT100-AUFNR AND
STOKZ = SPACE AND
STZHL = 0.
I had also cheked by createing an index for AUFNR in the table AFRU...it does not help.
Is there anyway that we can declare Key field while declaring the Internal table....?
ANy suggestions to fix the performance issue is apprecaited!
Regards,
Kittu

Hi,
Thank you for your quick response!
Rui dantas, i have lill confusion...this is my code below :
data : t_zscprt type standard table of ty_zscprt,
       wa_zscprt type ty_zscprt.
types : BEGIN OF ty_zscprt100,
        aufnr type zscprt100-aufnr,
        posnr  type zscprt100-posnr,
        ezclose type zscprt100-ezclose,
        serialnr type zscprt100-serialnr,
        lgort type zscprt100-lgort,
      END OF ty_zscprt100.
data : t_zscprt100 type standard table of ty_zscprt100,
       wa_zscprt100 type ty_zscprt100.
Types: begin of ty_afru,
            rueck type CO_RUECK,
            rmzhl type CO_RMZHL,
            iedd  type RU_IEDD,
            aufnr type AUFNR,
            stokz type CO_STOKZ,
            stzhl type CO_STZHL,
         end of ty_afru.
data : t_afru type STANDARD TABLE OF ty_afru,
        WA_AFRU TYPE TY_AFRU.
SELECT AUFNR
        POSNR
        EZCLOSE
        SERIALNR
        LGORT
        FROM ZSCPRT100 INTO TABLE T_ZSCPRT100
        FOR ALL ENTRIES IN T_ZSCPRT
        WHERE   AUFNR = T_ZSCPRT-PRTNUM
        AND   SERIALNR IN S_SERIAL
        AND    LGORT   IN S_LGORT.
    IF sy-subrc <> 0.
       MESSAGE ID 'Z2' TYPE 'I' NUMBER '41'. "BDCG87
       stop."BDCG87
    ENDIF.
  ENDIF.
SELECT    RUECK
              RMZHL
              IEDD
              AUFNR
              STOKZ
              STZHL
              FROM AFRU INTO TABLE T_AFRU
              FOR ALL ENTRIES IN T_ZSCPRT100
              WHERE RUECK IN S_RUECK     AND
                    AUFNR = T_ZSCPRT100-AUFNR AND
                    STOKZ = SPACE AND
                    STZHL = 0.
Using AUFNR, get AUFPL from AFKO
Using AUFPL, get RUECK from AFVC
Using RUEKC, read AFRU
In other words, one select joining AFKO <-> AFVC <-> AFRU should get what you want.
This is my select query, would you want me to write another select query to meet this criteria..
From AUFNR> I will get AUFPL from AFKO> BAsed on AUFPL I will get RUECK, based on RUEKC i need to read AFRU..but i need to select few field from AFRu based on AUFNR....
ANy suggestions wil be appreciated!
