kindly reply with suggestio

select kunnr
       bukrs
       from knb1
       into corresponding fields of table it_knb1
       where bukrs IN s_ccode.

if sy-subrc = 0.

sort it_knb1 descending by kunnr.

endif.

In the first select statement you have used into corresponding statement ...this is a problem here i guess.

Insted you can used

select kunnr

bukrs

from knb1

into table it_knb1

where bukrs IN s_ccode.

Provided it_knb1 has a structure of only kunnr and bukrs fields.

Hi,

select kunnr

name1

land1

regio

ktokd

from kna1

into table it_kna1

for all entries in it_knb1

where kunnr = it_knb1-kunnr

and ktokd = '0003'.

1. Here you are not checking whether IT_KNB1 is filled with some records or not. SO it wil not check for

the KUNNR value.

2. if sy-subrc = 0.

sort it_kna1 by kunnr.

Better to use delete adjacent duplicates.

if you want all the records, the copy the contents into a local internal table and then delete

the adjacent duplicates and use this in your select query.

endif.

hi,

put a break-point in each select query and check which select query is taking too much time..

and let us know, so that we can say what we need to change..

Hi,

after first select, create a temp internal table with same structure as it_knb1 .

i_tmp [ ] = it_knb1 [ ] .

sort i_tmp by kunnr.

delete adjacent duplicates from i_tmp comparing kunnr.

select kunnr

name1

land1

regio

ktokd

from kna1

into table it_kna1

for all entries in i_tmp

where kunnr = i_tmp -kunnr

and ktokd = '0003'.

For select from KNVV, use iternal table IT_KNA1 instead

select kunnr

zterm

from knvv

into table it_knvv

for all entries in it_kna1

where kunnr = it_kna1-kunnr.

This will speedup your retrieval.

Regards,

Dev.

Hi,

In the first select query , avoid statement into corresponding and before the second select query u have to use

if it_knb1[] is not initial.

select kunnr

name1

land1

regio

ktokd

from kna1

into table it_kna1

for all entries in it_knb1

where kunnr = it_knb1-kunnr

and ktokd = '0003'.

endif.

aslo in the below query , u have to change the partner type.instead of VE u have to give WE...Plz check

if not it_vbrk[] is initial.

select vbeln

parvw

pernr

kunnr

from vbpa

into table it_vbpa

for all entries in it_vbrk

where vbeln = it_vbrk-vbeln

and kunnr = it_vbrk-kunrg

and parvw = 'WE'.

if sy-subrc = 0.

sort it_vbpa by vbeln.

endif.

Hi Tanisha,

I would have written a JOIN query in this case.

Do let me know if i shud be putting efforts on the queries to JOIN them together.
