Yeah - format it so that we can read it more easily.

Have you used any tools to identify if and where there are problems?

See Dear First Format The Display properly .So After The Birds' Eye View we can suggest that never fetch all the fields from a table unless its not required in the code .It degrade the code performance so badly that u can only realize after running the se30.Anyway next better to use the key index of all the tables u r using in code.Or create another secondary index which is not a good habit.So better try for the first one.Never use select statement inside a loop.Alternatively u can use

'For all entries' Syntax Checking the emptiness for the parent table .

Use sort before reading a table.Next use binary search . Anyway u better to display it in proper format .Then we can discuss it more.

Expecting rewards If its usefull!!!!!!!!!

Anee,

You have to remove all select statements form loops.

Use FOR ALL ENTRIES.

Re: Performance suggestion

Former Member — Mon, 18 Feb 2008 09:56:29 GMT

Hi Anee,

Kindly declare the structure as per required fields for the corresponding fields. Donot reffer to the Direct database tables

as znpdreq.

form display_data .

DATA: i_npdreq TYPE TABLE OF znpdreq,

w_npdreq TYPE znpdreq.

data: i_link type table of crmd_link,

w_link type crmd_link.

data: i_partner type table of CRMD_PARTNER,

w_partner type CRMD_PARTNER.

data: i_but000 type table of but000,

w_but000 type but000.

data: i_orderadm_i type table of crmd_orderadm_i,

w_orderadm_i type crmd_orderadm_i.

*// Comments

As per Select Command written, Kindly Specify the required fields to be fetched, since it affects the performance as per se30.

select * into table i_npdreq from znpdreq

where object_id = w_orderadm_h-object_id

and process_type = 'ZNPD'.

If object_id = w_orderadm_h-object_id and process_type = 'ZNPD' is a unique combination then a single record will be fetched otherwise it will fetch all the records belongs to this

combination. Kindly check the table znpdreq which will be having other Primary key fields where as contaning unique values for all records.

Ans: Donot use ' process_type = 'ZNPD' ' in table statment, since all the records with ' process_type = 'ZNPD' '. Before using read statment sort the internal table with other primary key fields rather than object_id and process_type as per priority.

Then use read table i_npdreq into w_npdreq index '1'.

Otherwise go with binary search if the value known for the

sorting field specified above.

read table i_npdreq into w_npdreq

with key process_type = 'ZNPD'.

i_final-guid = w_orderadm_h-guid.

i_final-object_type = w_orderadm_h-object_type.

i_final-ZPRODNO = w_npdreq-ZPRODNO.

i_final-ZPRODMS = w_npdreq-ZPRODMS.

i_final-ZREQNO = w_npdreq-zreqno.

i_final-ZPRODNA = w_npdreq-ZPRODNA.

i_final-description = w_orderadm_h-description.

append i_final.

Follow the same as it is mentioned for Select Statement above.

select * into table i_orderadm_i from crmd_orderadm_i

where header = w_orderadm_h-guid.

Avoid writting this statement if there are more than one

records with this key field.

Follow the same as it is mentioned for internal table above.

read table i_orderadm_i into w_orderadm_i

with key header = w_orderadm_h-guid.

Donot use Loop Statment for a single record, since i_final

contains a single record so far, even the header is not yet

cleared, you can proceed with assigning field values.

i_final-ORDERED_PROD = w_orderadm_i-ORDERED_PROD.

i_final-DESCRIPTION_UC = w_orderadm_i-description_uc.

modify i_final where guid = w_orderadm_h-guid.

loop at i_final where guid = w_orderadm_i-header.

i_final-ORDERED_PROD = w_orderadm_i-ORDERED_PROD.

i_final-DESCRIPTION_UC = w_orderadm_i-description_uc.

modify i_final.

endloop." i_final orderadmi

select * into table i_link from crmd_link

where GUID_HI = w_orderadm_h-guid.

Kindly Avoid the nested Loop.*
Kindly Avoid the Select Query inside loop.*

loop at i_link into w_link.

loop at i_final where guid = w_link-guid_hi.

i_final-guid_hi = w_link-guid_hi.

i_final-guid_set = w_link-guid_set.

modify i_final.

endloop. "i_final for crmd_link

select * into table i_partner from crmd_partner

and partner_fct = '00000021'.

read table i_partner into w_partner

loop at i_final where guid_Set = w_partner-GUID.

Kindly follow the steps mentioned above. I am sure it will get you better solution.
