lp~xauto "item automatically created

lp~menge "quantity

lp~dmbtr "amount

ma~mtart "material group

ma~matkl "material type

INTO CORRESPONDING FIELDs OF TABLE i_mseg

FROM MKPF AS lk INNER JOIN MSEG AS lp

ON lk_{mblnr EQ lp}mblnr

INNER JOIN mara AS ma

ON ma_{matnr EQ lp}matnr

FOR ALL ENTRIES IN i_faglflexa

WHERE lp~prctr eq i_faglflexa-prctr

AND lp~matnr IN s_matnr

AND lp~xauto ne 'X'

AND lk~budat le s_budat-high

AND ma~mtart IN s_mtart

AND ma~matkl IN s_matkl.

plz guide me

thanks

Hi!

In the ON condition for the JOIN between MKPF and MSEG, try adding MJAHR. Also, donot use MARA in the join. The MSEG table itself is very huge, if you join MARA with it, it will definitely take a long time. Once you have retrieved data from MKPF and MSEG, create a new internal table with all the material numbers and SORT and delete adjacent duplicates. Using this table then access MARA to fetch the required fields using FOR ALL ENTRIES. Now looping at the MKPF_MSEG table, READ the MARA internal table to populate the required fields.

Cheers!

SELECT MBLNR
         MJAHR
         BUDAT
         FROM MKPF
         INTO TABLE IT_MKPF
         WHERE BUDAT IN S_BUDAT.

*--Read Records from MSEG for all entries in IT_MKPF
  IF NOT IT_MKPF[] IS INITIAL.
    SELECT MBLNR
            MJAHR
            ZEILE
            BWART
            MATNR
            WERKS
            MEINS
            ERFMG
            FROM MSEG
            INTO TABLE IT_MSMK
            FOR ALL ENTRIES IN IT_MKPF
            WHERE MBLNR = IT_MKPF-MBLNR AND
                  MJAHR = IT_MKPF-MJAHR AND
                 ( BWART = '131' OR BWART = '132' ) AND
                 MATNR IN S_MATNR AND
                 WERKS IN S_WERKS.
  ENDIF.

Now use Matnr of it_msmk to look into MARA tabel.

Generally, JOINS take much time. Please never use JOIN statements to fetch records.

Use for all entries, and let ur fields fetching be in an order and use INDEXes.
