In form process_data,

1. Loop inside Loop not permitted.

2. Select Query Inseide loop not at all permitted. Use FOR ALL ENTRIES...

Former Member · ‎10-12-2006

Hi,

1. First all remove all select * and select only the fields which you require for processing.

2. Since LIKP and LIPS are header and item table you can put a join between them, so that you can reduce a select

3. You need to remove select single * from BKPF and BSEG inside the LOOP and write it outside the LOOP.

4. Remove perform get_poinfo inside the LOOP and execute it separately.

5. Inside this perform get_poinfo, EKKO and EKPO are header and item level tables. So a inner join can be put on those tables.

Hope this will improve the performance of the report.

JLN.

Former Member · ‎10-12-2006

Hi,

1.In your select statements from LIKP,LIPS select required fields only. Use join for tables LIKP & Lips.

2.If required create index on table with fields vstel

lfdat & werks.

3.Avoid using nested loops. This would take more abap time.

4.Take out select single statements outside the loop and retreive data by using for all entries . Inside the loop do the same logic by using read statements ( Binary search).

These steps will definetly improve performance.

Sudheer

You can also use the transaction SE30 and monitor the program for the statements which are taking more time to excute.

Former Member · ‎10-12-2006

I would advice to couple the below query into one...

select * from likp into corresponding fields of table it_likp

where vstel IN s_vstel

and lfdat IN s_lfdat

and werks IN s_werks.

CHECK NOT it_likp[] IS INITIAL.

if p_grn is initial.

select * from lips into corresponding fields of table it_lips

for all entries in it_likp

where vbeln = it_likp-vbeln

and matnr IN s_matnr

and matkl IN s_matkl

and bwart IN ('641')

and LFIMG ne 0.

Change it to -->

-->Also instead of all fields list the ones you are planning to use.

select {list of fields}

into corresponding fields of table it_lips

from lips as a inner join likp as b on a_{vbeln = b}vbeln

where a~matnr IN s_matnr

and a~matkl IN s_matkl

and a~bwart IN ('641')

and a~LFIMG ne 0

and b~vstel IN s_vstel

and b~lfdat IN s_lfdat

and b~werks IN s_werks.

Former Member · ‎10-12-2006

Hi vijay

Regarding your program to reduce the execution time you can do following things in your program :

1) Avoid the following select * statements in the

FORM get_data .

select * from likp into corresponding fields of table it_likp

where vstel IN s_vstel

and lfdat IN s_lfdat

and werks IN s_werks.

select * from lips into corresponding fields of table it_lips

for all entries in it_likp

where vbeln = it_likp-vbeln

and matnr IN s_matnr

and matkl IN s_matkl

and bwart IN ('641')

and LFIMG ne 0.

<b>Instead you can select only the required fields into your internal tables it_likp & it_lips</b>. we must avoid select * statements . try not using into corresponding instead define your internal table according to field required. and use select field1 field2 .. from table name into table ITAB where...

2) In start of selection you can have perform get_data above other perform and these three

PERFORM build_eventtab USING gt_events[].

PERFORM build_comment USING heading[].

PERFORM build_layout

can be above PERFORM display_data if itab is not initial.

Just try both it might solve your problem

Thanks

Hi,

Most of the performance problems are due to the database statements. Open SQl statements. Please use the columns names instead of '*' where ever possible and avoid into corresponding fileds of table. This is a costly operation.

Where ever you use select single try and see if you can implement signle record buffering for the table.

Where ever possible dont use negative statements in Where clause and avoid using IN for range tables unless it is very important for your functionality.

Never execute select in a loop, try and see if you can use into table and appending table instead.

select * into table itab or

select * appending table itab.

Hope the above will help you.

Regards,

Sesh
