Help with INNER JOIN

[Former Member]

Hi All,

The following code takes a lot of time to execute. Can anyone suggest to fine tune the following inner join statement.

SELECT a_{ebeln a}ebelp a_{txz01 a}matnr a~werks

a_{lgort a}menge a_{meins a}netpr a~peinh

a_{webaz a}insmk a_{pstyp a}knttp a~labnr

a_{konnr a}ktpnr a_{evers a}kunnr a~adrnr

a_{revlv a}emlif a_{adrn2 a}mtart a_{elikz a}retpo

b_{lifnr b}ekgrp b_{waers b}bedat b~inco1

b_{inco2 c}etenr c_{eindt c}slfdt c~menge

c_{wemng d}banfn d~bnfpo

INTO TABLE t_po

FROM ekko AS b

INNER JOIN ekpo AS a

ON a_{ebeln EQ b}ebeln

INNER JOIN eket AS c

ON c_{ebeln EQ a}ebeln

AND c_{ebelp EQ a}ebelp

LEFT OUTER JOIN eban AS d

ON a_{ebeln EQ d}ebeln

AND a_{ebelp EQ d}ebelp

WHERE b~ebeln IN s_ebeln "Purchasing Document

AND b~bsart IN s_bsart "Document Type

AND b~loekz EQ space "Deletion Indicator, Header

AND b~lifnr IN s_lifnr "Vendor Number

AND b~ekorg IN s_ekorg "Purchasing Organization

AND b~ekgrp IN s_ekgrp "Purchasing Group

AND b~bedat IN s_bedat "Document Date

AND b~bukrs IN s_bukrs

AND a~elikz = space "delivery not complete

AND a~loekz EQ space "Deletion Indicator, Line

AND a~txz01 IN r_txz01 "Short Text

AND a~matnr IN s_matnr "Material Number

AND a~werks IN s_werks "Plant

AND a~lgort IN s_lgort "Storage Location

AND a~matkl IN s_matkl "Material Group

AND a~idnlf IN s_idnlf "Vendor's Material Number

AND a~pstyp IN r_pstyp "Item Category

AND a~knttp IN s_knttp "Account Assign. Category

AND a~bstae IN s_bstae "Confirmation Control Key

AND c~eindt IN s_eindt. "Item Delivery Date

Check that s_ebeln is not empty before doing the select.

Also, your last join:

    LEFT OUTER JOIN eban AS d
      ON a~ebeln EQ d~ebeln
      AND a~ebelp EQ d~ebelp

doesn't use an index. Remove this and see if it speeds things up. If it does, see if there's another way to get this data.

To follow up on Rob's suggestion, BANFN and BNFPO are on EKPO.
