Performance issue with select query and for all entries.

hi,
i have a report to be performance tuned.
the database table has around 20 million entries and 25 fields.
so, the report fetches the distinct values of two fields using one select query.
so, the first select query fetches around 150 entries from the table for 2 fields.
then it applies some logic and eliminates some entries and makes entries around 80-90...
and then it again applies the select query on the same table using for all entries applied on the internal table with 80-90 entries...
in short,
it accesses the same database table twice.
so, i tried to get the database table in internal table and apply the logic on internal table and delete the unwanted entries.. but it gave me memory dump, and it wont take that huge amount of data into abap memory...
is around 80-90 entries too much for using "for all entries"?
the logic that is applied to eliminate the entries from internal table is too long, and hence cannot be converted into where clause to convert it into single select..
i really cant find the way out...
please help.

Even though you tried to ask the question with detailed explanation, unfortunately it is still not clear.
It is perfectly fine to access the same database twice. If that is working for you, I don't think there is any need to change the logic. As Rob mentioned, 80 or 8000 records is not a problem in "for all entries" clause.

It is not clear what you tried to do here. Did you try to bring all 20 million records into an internal table? That will certainly cause the program to short dump with memory shortage.

That is fine. Actually, it is better (performance wise) to do much of the work in ABAP than writing a complex WHERE clause that might bog down the database.

Select query like For all Entries

Hi,
I have a requirement like:
I need to extract data (BKTXT) from table BKPF based on some criteria, into one internal table and I need to query on REGUP table for the above data, the selection criteria on REGUP as follows:
BKTXT(Document Header Text with 25 Char) is a combination of DATE and character string.
Ex: bkpf-bktxt = 20060710-PL02 (YYYYMMDD)
it is like LAUFD + LAUFI (of table REGUP)
i.e: LAUFD (REGUP) = 07/10/2006 (MM/DD/YYYY) and LAUFI(REGUP) = PL02
here I am thinking to use a select query on REGUP using FOR ALL ENTRIES of table i_bkpf..
How can I change the date format YYYYMMDD to MM/DD/YYYY for my requirement?
(( Run-on Date (REGUP-LAUFD) = the first 8 characters in the Document Header Text (BKPF- BKTXT) in MM/DD/YYYY date format (e.g. 07/10/2006)
 Run ID (REGUP-LAUFI) = the 10th character through the 15th character in the Document Header Text (BKPF- BKTXT)

It is not possible to do in the way you are thinking of doing. "For all entries" requires you to have the itab table field and the database table field to have the same type and length. So something like below will not work.
TABLES: regup.
DATA: BEGIN OF itab OCCURS 0,
 text LIKE bkpf-bktxt.
DATA: END OF itab.
DATA: BEGIN OF itab_regup OCCURS 0.
 INCLUDE STRUCTURE regup.
DATA: END OF itab_regup.
SELECT * INTO TABLE itab_regup
 FROM regup FOR ALL ENTRIES IN itab
 WHERE laufd = itab-text+0(8).
If you run this code, you will get an error as follows:
"When using the addition "FOR ALL ENTRIES IN itab", the fields "LAUFD" and "ITAB-TEXT+0(8)" must have the same type and length."

Make this query into for all entries

Hello Experts,
please change this query into for all entries to increase performance
loop at itab1.
    SELECT single b~vtext INTO itab2
     FROM vbkd AS a
        INNER JOIN tvkggt AS b
        ON akdkg1 = bkdkgr
     WHERE a~vbeln EQ itab1-vbeln_vauf
     AND a~posnr EQ itab1-posnr_vauf.
endloop.
Thank you so much for all the replies.

as I write again and again, then performance is mainly increased but correct index usage
SELECT single b~vtext
INTO itab2
FROM vbkd AS a
INNER JOIN tvkggt AS b
ON   ..... spras ???
       bkdkgr = akdkg1
WHERE a~vbeln EQ itab1-vbeln_vauf
AND      a~posnr EQ itab1-posnr_vauf.
You access vbkd with the primary key vbeln and posnr
and then you switch to tvkggt where you need spras and kdgr for the primary key
With spras you statement is incorrect you get one text it is unclear in which language,
it might be that there is onyl one, but still you *** it to the statement to use the index.
spras = sy-langu might be o.k.
I.e.
IF NOT ( itab1 is initial ).
   SELECT single b~vtext
       INTO itab2
       FROM vbkd AS a
       INNER JOIN tvkggt AS b
       ON   b~spras = sy_langu
              b~kdkgr = a~kdkg1
       FOR ALL ENTRIES in itab1
       WHERE a~vbeln EQ itab1-vbeln_vauf
       AND      a~posnr EQ itab1-posnr_vauf.
ENDIF.

Select ... for all entries problem

Hi,
I'm making select statements to BKPF and BSEG, but I can't do an inner join between this two table because BSEG it's a cluster table so I have to do a SELECT... FOR ALL ENTRIES, but in SE16 I make the same query that I have writen in my program as shown below,
SELECT BUKRS BELNR GJAHR BUDAT MONAT
FROM BKPF INTO CORRESPONDING FIELDS OF TABLE it_bkpf
WHERE BUKRS = 'XXX'
AND        GJAHR = '2005'
AND        BELNR = '0000000250'. "just for proof
AND        MONAT = '10'
The above query returns me 1 row in program and in SE16 and then I make the next query for BSEG to do the join
SELECT BUKRS BELNR GJAHR BSCHL SHKZG WRBTR HKONT
FROM BSEG INTO CORRESPONDING FIELDS OF TABLE IT_BSEG
FOR ALL ENTRIES IN it_bkpf
WHERE bukrs = it_bkpf-bukrs
and gjahr = it_bkpf-gjahr
and belnr = it_bkpf-belnr.
this query returns 897 rows and in SE16 this same query returns 901 rows
Why SELECT...FOR ALL ENTRIES brings me less rows affected by the query in SE16
Thanks for your help!!

Hi,
Please use the following code for selcting the exact number of rows.
IF it_bkpf[] IS NOT INITIAL.
SELECT *
FROM BSEG INTO CORRESPONDING FIELDS OF   TABLE    IT_BSEG
FOR ALL ENTRIES IN it_bkpf
WHERE bukrs = it_bkpf-bukrs
and gjahr = it_bkpf-gjahr
and belnr = it_bkpf-belnr.
ENDIF.
Instead of * ,you can specify the exact fields required along with all the key fields as selection fields.Also it is must to check the condition it_bkpf[] IS NOT INITIAL before using the statement FOR ALL ENTRIES IN it_bkpf.Suppose if this condition is not used and if it_bkpf is initial,it will fetch all entries from the table.
Reward if helpful.

Issue with Select Query in the Delivery userexit USEREXIT_SAVE_DOCUMENT

Hi All,
I am facing a strang issue with delivery userexit
1) I have a delivery user exit MV50AFZ1 - USEREXIT_SAVE_DOCUMENT.
2) In this user exit. I have written a select query as shown below
*Get the already delivered data
 SELECT vbeln
 vgbel
 vgpos
 erdat
 erzet
 lfimg
 FROM lips
 INTO TABLE t_lips
 FOR ALL ENTRIES IN t_xlips_reference
 WHERE vgbel EQ t_xlips_reference-vgbel
 AND vgpos EQ t_xlips_reference-vgpos.
 IF sy-subrc EQ 0.
 ENDIF.
3) The use of the above select query is to find out if there is any delivery that has already been created for the reference slaes order for which the current delivery is being created.
4) The issue here is that for the FIRST DELIVERY, this select query should fail becuase there is no delivery created earlier and LIPS table would not have data. But, I am seeing some data getting populated in the internal table. The data that I am seeing in the internal table is the data of XLIPS which is nothing but the one that is about to get saved in the database after finishing this userexit.
5) STRANGE Point is that this is working fine in case if I create delivery using the transaction VL01N. But, if I create delivery using VL10A program I am facing this issue.

> How to use for all all entries in the above inner join for better performance?
my best christmas recommendation for performance, simply ignore such recommendations.
And check the performance of your join!
Is the performance really low, if it is then there is probably no index support. Without indexes FOR ALL ENTRIES will be much slower.

Select fom table for all entries where field starts with value

Hello
I want to write a select like this
select * from bsis
into lt_bsis
for all entries in lt_itab
where xblnr like lt_itab-belnr%
I want to select all the entries from bsis where the field xblnr starts with the values found in lt_itab-belnr.
for example
ls_itab-belnr = 5100000028
bsis-xblnr = 510000002810001
                    510000002810002

                    520000002810001
and i want to select only the entries that start with 5100000028 in this case
Can anybody help?

The statement has to be in a special format, so it might make sense run a trace in DEV, check the "Explain" there and download/upload the statement to QA (also via ST05). I have not tried this myself yet, so I would be interested if it works
Here is two resources for you, SAP online help and a good blog by Siegfried Boes:
http://help.sap.com/saphelp_erp60_sp/helpdata/EN/d1/801f7c454211d189710000e8322d00/frameset.htm
The SQL Trace (ST05) Quick and Easy
It's a very powerful analysis tool, so it's worth the time to work yourself into it.
But again, you actually want good test data in DEV for this matter.

Performance issue with selection of line items.

Hi All.
I am facing seriour Time_Out error problem for my program. Actually i am developing RFC and i have to send data to non sap system as it is in sap tables. Now i have to send data for BSIS for new entries for a day. SO first i search BELNR for CPUDT in BKPF and then use for all entries on BSIS. But now my problem is for a single day i am getting 1679 documents from BKPF and when i use for all entries in BSIS, it will give time out error.
my code is like
SELECT BUKRS BELNR GJAHR
   FROM BKPF INTO CORRESPONDING FIELDS OF TABLE I_BKPF
      WHERE CPUDT IN S_CPUDT.
if i_bkpf[] is not initial.
SELECT * FROM BSIS INTO TABLE I_BSIS
   FOR ALL ENTRIES IN I_BKPF
      WHERE BUKRS = I_BKPF-BUKRS
                   BELNR = I_BKPF-BELNR
                   GJAHR = I_BKPF-GJAHR.
endif.
So please gurus help me ..its urgent..

Instead of writing Select * write Select "Fields names" then try might be it will solve ur problem.

Hi Sandy,
You indicated the size of the tables and index, what is the total number of records in your BSIS?
In your range tables, make sure they are postive formed.
Ex. r_bukrs : I EQ '1001', and not I NE '1000'.
You should consider coding your statements to check for input for bldat, code it with r_bldat and then another set without. It should be better performance to not have empty where conditions. So two routines, Selects with bldat and without.
Don't know if you have a Basis person to help analyze the performance, but you should look at the indexes in BSIS. You may have several indexes that contain some of your input fields but they may be spread across several indexes or there may be none. But say you have 5 indexes and it happens that just one of your parameters are in each of those indexes. Well, it can only use one index so while you think you are providing alot of parameters to help performance only one field is being used to access the index. What you need to do then is to find an index that has the most fields in your where clause and see if you can add to that, so long it's not an SAP index. If it's a z index consider adding additional fields to it, or consider creating a new index.
You can at least analyze the first Select in your DEV client. Run a trace, ST05 and then execute your code. It will show you which index it has used if any.
Also, look at the query values it is passing to the database. You said you get 6 M records on the first Select. This just seem like a lot of records, which is for just one account number (v_tosdef) along with the other parameters. I'm wondering if there's a problem with your input data. With 6M in your first table, your FOR ALL ENTRIES statement will be executed 1.2 million times. Tyically the database interface breaks down your Select-For All entries statement into 5 records per query. Again, run ST05 and you will see this.
In SE16, on your BSIS table, what is your count of records if you enter only the account number?
As a test, you might want to try entering all your parameters in SE16, run ST05 to trace the SQL to see what it is doing. You may have to kill your SE16 session or it may time out on you. You can stop your ST05 trace before your SE16 finishes and it will still show how SAP is going after the data and what index it used.
Let me know if this helped any.

Advice required on a select statement using "FOR ALL ENTRIES"

Hi,
this is really intresting ...
I have a small requirement where in i have to find out
the valid entries in my internal table (T_MATNR) by using a select statement to a check table (MARA) which has all the fields present in the internal table T_MATNR.
Select statement is
SELECT MATNR
 MTART
 from MARA
 for all entries in T_MATNR
 into table T_MATNR
 where matnr eq T_MATNR-MATNR.
If you observe the itab in the option 'FOR ALL ENTRIES' and the destination table is the same. I want to know whether this is correct? will it cause any performance issue? right now this statement is working fine for me.

Hi,
U have to use
SELECT MATNR
MTART
from MARA
into table I_MATNR(different table)
for all entries in T_MATNR
where matnr eq T_MATNR-MATNR.
If u r specifying both same table name then for what entries it will retrieve, if u have alreay selected some entries and appending u can use
SELECT MATNR
MTART
from MARA
into table T_MATNRwhere matnr eq T_MATNR-MATNR.
then
SELECT MATNR
MTART
from MARA
appending table T_MATNR
for all entries in T_MATNR
where matnr eq T_MATNR-MATNR.
In this way u can do.
Hope u got it.

Using delete and FOR ALL ENTRIES

Hi,
We have a error message regarding the following code :
Delete FROM TABLE FOR ALL ENTRIES IN lt_TABLE WHERE
TABLE_KEY1 = LT_TABLE_KEY1
Could we use the For All entries with "Select" ?
For information, the error message is "Unable to interpret "FOR". Possible causes: Incorrect spelling or comma error.
Thank you.

Hi,
Check the below syntax, if you want to delete from database
DELETE FROM sflight
WHERE carrid = p_carrid AND
fldate = sy-datum AND
seatsocc = 0.
Just a suggestion. May be from next time you can use F1 help for syntax:
1. Place the cursor on the delete keword in your program and press F1 - You willl get all the possible syntax for delete statement
2. Else open the transaction ABAPDOCU, Click Keyword Help, Enter the required keyword(delete in this case) and press cont.. You will get the syntax.
Hope thsi will help you.
