Hi all,

I wrote logic like this.But it getting performance problem.

Can anybody tell me how to avoid this.

SELECT * INTO TABLE wknvv

FROM knvv

WHERE vkorg IN sales_or

AND vtweg IN dist_cha

AND spart IN div

AND vkbur IN sales_of .

LOOP AT wknvv .

SELECT vbeln auart zzmax_cpi INTO (wlist-vbeln,wlist-auart,max)

FROM vbak

WHERE

vbtyp = 'G'

AND kunnr = wknvv-kunnr

AND auart IN contr_ty.

max1 = max.

IF sy-subrc = 0 AND max1 IS NOT INITIAL .

SELECT * INTO wvbap FROM vbap

WHERE vbeln = wlist-vbeln

AND abgru = ''.

IF sy-subrc = 0.

SELECT SINGLE * FROM veda INTO wveda

WHERE vbeln = wlist-vbeln

AND vposn = wvbap-posnr

AND vkuegru = ''

AND venddat IN dates .

IF sy-subrc = 0.

MOVE-CORRESPONDING wvbap TO wlist .

MOVE-CORRESPONDING wveda TO wlist .

MOVE-CORRESPONDING wknvv TO wlist .

APPEND wlist.

ENDIF .

ENDIF.

ENDSELECT.

CLEAR wlist.

ENDIF.

ENDSELECT .

ENDLOOP.

please give me solution immediatly.

I will give full points.

Can you please tell me why you are using so many select statements within a loop when you can have so may statements like READ TABLE , FOR ALL ENTRIES or JOIN STATEMENTS.

Shall i write then for you?

Hi Rakesh,

rite now i m not on the system but

you can write the query like this.

SELECT * INTO TABLE wknvv

FROM knvv

WHERE vkorg IN sales_or

AND vtweg IN dist_cha

AND spart IN div

AND vkbur IN sales_of .

then do the for all entries of WKNW

CREATE a table type with 3 fields for WLIST

SELECT vbeln auart zzmax_cpi

INTO TABLE wlist

FOR ALL ENTRIES IN wknw

FROM vbak

WHERE

vbtyp = 'G'

AND kunnr = wknvv-kunnr

AND auart IN contr_ty.

delete wlist where zzmax_cpi = 0.

SELECT * INTO TABLE wvbap

FROM vbap

FOR ALL ENTRIES OF wlist

WHERE vbeln = wlist-vbeln

AND abgru = ''.

IF sy-subrc = 0.

SELECT SINGLE *

FROM veda

INTO TABLE wveda

FOR ALL ENTRIES OF wlist

WHERE vbeln = wlist-vbeln

AND vposn = wvbap-posnr

AND vkuegru = ''

AND venddat IN dates .

here you have to create two more Internal tables WVEDA and WLIST

Hope this is useful to u...
