Vbrk and Vbrp tables performance problem

Question

Hi all,
The below query is taking lot of time in QAS i need to decrease the time without affecting the logic.....
  SELECT vbrk~kunag
       vbkd~bstkd
       vbkd~bstdk
       INTO TABLE c_tab_po FROM vbrp
       INNER JOIN vbrk ON vbrkmandt = vbrpmandt AND vbrk~vbeln =
       vbrp~vbeln
       INNER JOIN vbkd ON vbkdmandt = vbrpmandt AND vbkd~vbeln =
       vbrp~aubel
                          AND vbkd~posnr = con_zposnr
       WHERE vbrp~vbeln EQ nast-objky.
  DELETE ADJACENT DUPLICATES FROM c_tab_po COMPARING ALL FIELDS.
*Getting the other Invoices based on the customer PO number
  IF c_tab_po[] IS NOT INITIAL.
    SELECT
    vbrk~kunag
    vbkd~bstkd
    vbkd~bstdk
    vbkdposex_e vbrkvkorg
    vbrpvbeln vbrpposnr vbrp~erdat
           vbpakunnr vbrpaubel vbrpaupos vbakerdat
           vbrpmatnr vbrkmwsbk vbrp~netwr
           vbrkvaldt vbrkzterm vbrk~vbtyp
            INTO TABLE g_tab_invoice FROM vbrp
            INNER JOIN vbrk ON vbrkmandt = vbrpmandt AND vbrk~vbeln =
            vbrp~vbeln
            INNER JOIN vbkd ON vbkdmandt = vbrpmandt AND vbkd~vbeln =
            vbrp~aubel
                           AND vbkd~posnr = con_zposnr
            INNER JOIN vbpa ON vbpamandt = vbrpmandt AND vbpa~vbeln =
            vbrp~aubel
                           AND vbpaposnr = con_zposnr AND vbpaparvw =
                           con_parvw
            INNER JOIN vbak ON vbakmandt = vbakmandt AND vbak~vbeln =
            vbrp~aubel
            FOR ALL entries IN c_tab_po
                WHERE vbrk~kunag EQ c_tab_po-kunag AND
                vbkd~bstkd EQ c_tab_po-bstkd AND
                vbkd~bstdk EQ c_tab_po-bstdk.
  ENDIF.

Hi Younus,
First join seems to be oku2026
But you are querying Db tables multiple times to avoid this.
Fetch the fields
vbkdposex_e vbrkvkorg
vbrpvbeln vbrpposnr vbrp~erdat
vbrpaubel vbrpaupos
vbrpmatnr vbrkmwsbk vbrp~netwr
vbrkvaldt vbrkzterm vbrk~vbtyp
in the first join itself.
SELECT vbrk~kunag
vbkd~bstkd
vbkd~bstdk
vbkd~posex_e vbrk~vkorg
vbrp~vbeln vbrp~posnr vbrp~erdat
vbrp~aubel vbrp~aupos
vbrp~matnr vbrk~mwsbk vbrp~netwr
vbrk~valdt vbrk~zterm vbrk~vbtyp
INTO TABLE c_tab_po FROM vbrp
INNER JOIN vbrk ON vbrk~mandt = vbrp~mandt AND vbrk~vbeln =
vbrp~vbeln
INNER JOIN vbkd ON vbkd~mandt = vbrp~mandt AND vbkd~vbeln =
vbrp~aubel
AND vbkd~posnr = con_zposnr
WHERE vbrp~vbeln EQ nast-objky.
then Just join VBPA & VBAK and get required data.
Thanks,
