Query takes a long time on EBAN table

Question

Hi,
I am trying to execute a simple select statement on EBAN table. This query takes unexpectionally longer time to execute.
Query is :
SELECT banfn bnfpo ernam badat ebeln ebelp
      INTO TABLE gt_eban
      FROM eban FOR ALL ENTRIES IN gt_ekko_ekpo
      WHERE
      banfn IN s_banfn AND
      ernam IN s_ernam
      and ebeln = gt_ekko_ekpo-ebeln AND
      ebelp = gt_ekko_ekpo-ebelp.
Structure of gt_ekko_ekpo
TYPES : BEGIN OF ty_ekko_ekpo,
        ebeln TYPE ekko-ebeln,
        ebelp TYPE ekpo-ebelp,
        bukrs TYPE ekko-bukrs,
        aedat TYPE ekko-aedat,
        lifnr TYPE ekko-lifnr,
        ekorg TYPE ekko-ekorg,
        ekgrp TYPE ekko-ekgrp,
        waers TYPE ekko-waers,
        bedat TYPE ekko-bedat,
        otb_value TYPE ekko-otb_value,
        otb_res_value TYPE ekko-otb_res_value,
        matnr TYPE ekpo-matnr,
        werks TYPE ekpo-werks,
        matkl TYPE ekpo-matkl,
        elikz TYPE ekpo-elikz,
        wepos TYPE ekpo-wepos,
        emlif TYPE ekpo-emlif,
  END OF ty_ekko_ekpo.
Structure of GT_EBAN
TYPES : BEGIN OF ty_eban,
  banfn TYPE eban-banfn,
  bnfpo TYPE eban-bnfpo,
  ernam TYPE eban-ernam,
  badat TYPE eban-badat,
  ebeln TYPE eban-ebeln,
  ebelp TYPE eban-ebelp,
  END OF ty_eban.
Query seems to be OK to me. But still am not able to figure out the reason for this performance issue.
Please provide your inputs.
Thanks.

Hi Richa,
Maybe you are executing the query with S_BANFN empty. Still based on the note 191492 you should change your query on like the following
1st Suggestion:
if gt_ekko_ekpo[] is not initial.
SELECT banfn banfpo       INTO TABLE gt_eket
      FROM eket FOR ALL ENTRIES IN gt_ekko_ekpo
      WHERE
     ebeln = gt_ekko_ekpo-ebeln AND
      ebelp = gt_ekko_ekpo-ebelp.
if sy-subrc = 0.
delete gt_eket where banfn not in s_banfn.
if gt_eket[] is not initial
SELECT banfn bnfpo ernam badat ebeln ebelp
      INTO TABLE gt_eban
      FROM eban FOR ALL ENTRIES IN gt_eket
      WHERE
      banfn = gt_eket-banfn
     and  banfpo = gt_eket-banfpo.
if sy-subrc = 0.
  delete gt_eban where ernam not in s_ernam.
endif.
endif.
endif.
endif.
2nd Suggestion:
if gt_ekko_ekpo[] is not initial.
SELECT banfn banfpo       INTO TABLE gt_eket
      FROM eket FOR ALL ENTRIES IN gt_ekko_ekpo
      WHERE
     ebeln = gt_ekko_ekpo-ebeln AND
      ebelp = gt_ekko_ekpo-ebelp.
if sy-subrc = 0.
delete gt_eket where banfn not in s_banfn.
if gt_eket[] is not initial
SELECT banfn bnfpo ernam badat ebeln ebelp
      INTO TABLE gt_eban
      FROM eban FOR ALL ENTRIES IN gt_eket
      WHERE
      banfn = gt_eket-banfn
     and  banfpo = gt_eket-banfpo
     and ernam in s_ernam.
endif.
endif.
endif.
Hope this helps.
