Please Help optimize the following query.

SELECT HKONT GSBER BUKRS AUGDT BUDAT SHKZG

DMBTR WAERS AUGBL ZUONR GJAHR BELNR BUZEI

INTO TABLE T_BSIS_TEMP

FROM BSIS

FOR ALL ENTRIES IN T_SKB1

WHERE BUKRS EQ T_SKB1-BUKRS

AND HKONT EQ T_SKB1-SAKNR

AND BUDAT LE P_BUDAT.

IF SY-SUBRC = 0.

DELETE T_BSIS WHERE NOT GSBER IN S_GSBER.

T_BSIS[] = T_BSIS_TEMP[].

SORT T_BSIS BY BUKRS HKONT GSBER.

ENDIF.

Thanking you.

There is nothing much you can do with the SELECT query but just take care of the below tips.

1. Check if the T_SKB1 is not initial.

2. Sort the table T_SKB1

3. Make sure to delete adjacent duplicates for Bukrs and Saknr.

In addition to the others, you can move the criteria for GSBER ito the SELECT statement:

SELECT  hkont gsber bukrs augdt budat shkzg
        dmbtr waers augbl zuonr gjahr belnr buzei
  INTO TABLE t_bsis_temp
  FROM bsis
  FOR ALL ENTRIES IN t_skb1
  WHERE bukrs EQ t_skb1-bukrs
    AND hkont EQ t_skb1-saknr
    AND budat LE p_budat
    AND gsber IN s_gsber.

IF sy-subrc = 0.
  t_bsis[] = t_bsis_temp[].
  SORT t_bsis BY bukrs hkont gsber.
ENDIF.

If Performance is still an issue then you might want to consider creation of a new index on the bsis table for fields BUKRS, HKONT and BUDAT.

Apart from all the above solutions.

i broke down the data into logical units of 400 and processed it.

Thank you all.

Hi,

From the driver table you may delete all the adjacent duplicates comparing all fields. While using for all entries pl make sure the driver table is not empty .

eg.

IF NOT T_SKB1[] IS INITIAL.

Select Stmt

Endif.

If helpful pl reward.

Cheers....
