Fetch from MBEW table

Hi,
I have a situation where I need to fetch some records form MSEG table and for each record fetched I need to get the Standard Price(STPRS) from MBEW table.
But for fetching a unique record from MBEW table, I need to fetch based on its primary keys - MATNR, BWKEY, BWTAR.
What values should I pass for BWKEY and BWTAR for fetching a unique record?
I searched in SDN and found that BWKEY can have values Plant or Company Code. But I'm not sure when I should populate it with Plant and when I should populate it with company code.
Thanks in advance.
Sreeraj Pulickal

Hi,
See the SAP documentation of BWKEY. It clearly specifies when to pass Company Code
Valuation area
    Organizational level at which the material is valuated. A valuation area
    can be one of the following:
    o   Plant
    o   All plants belonging to a company code, in which case the valuation
        area is the company code
Edit :
Regarding valuation type, you can get the valuation category(BWTTY) from MARC by passing Material Number and Plant.
Get tye valuation Type from Table T149C by passing BWTTY as input parameter.

Data fetching from BSEG table

Hi,
I have used smartforms for generating suppler payment statement for financial department. more time duration is taken by the program when it is generating.
I think this problem comes while data fetching from BSEG table. because, it has more records for one vendor ID.
I want reduce this time duration.
Please guide me.

Have you tried this selection in se16? I'm quite sure that It will take
a long time.
The problem has been explained in this group before and I think you
should search for bseg in the answers given.
As a hint: It has to do with the selection universe. You are restricting
only bukrs from the primary key (all the other restrictions in your
where clause are filters that are applied on SAP's side (not on the
database side)). The problem is that bseg isn't stored as separated
fields in the RDBMS, but as a table with the primary key and a stream of
bits in a raw field.
You should review and change the logic you're using before reading bseg.
It's the only way you'll improve the performance of this select. (for
example, you could use one or more secondary index tables - bi or ba
to retrieve belnr and access bseg with a better where clause).

Perofrmance issue on data fetch from db table

Dear Experts,
I have one requirement which explained below step wise.
Step - 1 : I have a parameter on selection screen from where i ll get my ebeln value (User Input field) and that ebeln i ll check in ekpo table for validations.
If valid i keep it in a variable gw_ebeln.
Step - 2 : Need to fetch lifnr fron ekko based on gw_ebeln value.
Step - 3 : Need to fetch adrnr from lfa1 based on lifnr (Previously fetched from ekko table in step 2)
Step - 4 : Need to fetch email field from adr6 table based on adrnr value (Previously fetched from lfa1 table in step 3)
Step - 5 : Now for these mail id , I need to send mail by given fm.
My question is : I can create structure for step 2 , step 3, step 4 and by using " for all entries " in select statement i ll fetch my mail id in step 4.
So instead of creating structure and then use for all entries , I can fetch by using "select single" statement for step 2 , step3 step 4.bcz i am fetching only one field from all 3 table.
So which one is better performance wise and why ?
I need more and clear clarifications on these difference.
Please provide me suggestions.
Thanks & Regards,
Ajit Sarangi

Hi Ajit,
We are referring item table EKPO. Multiple entries are possible.
To append the values in final internal table, we are going to process the LOOP. Inside loop, we should not use the Select statement, that decreases the performance. Database Interaction process should not done inside Loop...Endloop.
That's why we are creating the Internal table for processing the values. Since we need limited number of fields in the particular table, we are creating our own structure in the program.
For this case, For all entries will give better performance with compare to Select Single.

Select query for fetching from 3 tables.

Can we have a single Select query for fetching same fields (kappl,kschl,vkorg,vtweg,spart,kunwe,datbi,knuma,datab,knumh)
from 3 tables >> KOTE707,KOTE708 and KOTE709 into an internal table for a particular KUNNR?
Regards,
Shashank.

Hi,
If you have kunnr field in all the 3 tables then it is possible. use inner join as below
PARAMETERS: p_cityfr TYPE spfli-cityfrom,
            p_cityto TYPE spfli-cityto.
DATA: BEGIN OF wa,
         fldate TYPE sflight-fldate,
         carrname TYPE scarr-carrname,
         connid   TYPE spfli-connid,
       END OF wa.
DATA itab LIKE SORTED TABLE OF wa
               WITH UNIQUE KEY fldate carrname connid.
SELECT c~carrname p~connid f~fldate
       INTO CORRESPONDING FIELDS OF TABLE itab
       FROM ( ( scarr AS c
         INNER JOIN spfli AS p ON p~carrid   = c~carrid
                              AND p~cityfrom = p_cityfr
                              AND p~cityto   = p_cityto )
         INNER JOIN sflight AS f ON f~carrid = p~carrid
                                AND f~connid = p~connid ).
LOOP AT itab INTO wa.
WRITE: / wa-fldate, wa-carrname, wa-connid.

Hi Manoj,
You have to make an Ajax call to display data without refreshing the page. Search this forum for Ajax and you can find lots of related posts. This link might help too. http://www.dba-oracle.com/t_html_db_apex_ajax_application_express.htm

Data fetching from Standard tables or transaction to SAP PI

Dear Friends !
Good day ! How are you ?
I have one requirement , My client asks me to develop a solution in that I should get the data from standard SAP tables like EKKO, EKPO ( MM related ) etc.. and send it to PI system and then PI system sends it to third party system database system.
We have current scenario is working fine, I have abap proxy that I called in various standard transaction codes ( MIRO, MIGO, etc ) ' Baddis just beforethe commit stament and it passed the data to SAP PI system and it sends to SQL system.
but my client dont want me to use Baddis. Client wants like u should read from those EKKO,EKPO tables as soon as you get new entry there and send it to PI system. I have no clue How can I go further in that. Shall I use events ? but then question is same I need to trgger them somewere? Is any one have idea How I can send the data to PI system frm SAP standard tcodes and tables without using Baddis.
Please reply me. your any help will be appreciated.
Regards
Naeem

The current Approach of your development perfectly good approach,
it is not possbiel to read data directly from SAP Tables, you have to use IDoc/RFC/Proxy,if you want to avoid BADI's then better to contact ABAP Team, they will help you different approches .
But you have to use Porxy/IDoc/BAPI for sure.

Values from CRCO Table.

Hi all ,
I need to retreive some values from CRCO table based on the balues fetched from AFRU table. I am writing a select like this
select single KOKRS KOSTL into table itab from CRCO
          where OBJTY = 'A'
             and OBJID = AFRU-ARBID
             and ENDDA >= AFRU-BUDAT
             and BEGDA <= AFRU-BUDAT.
As I need to retreive a single record from above select, but as a result i am getting multiple records.
Can anybody tell me what other keys from AFRU I can specify in the select in order to fetch only a single record.
Thanks,
Mungala.

Object ID you can get from ARBID from AFRU Table. Put value of ARBID in OBJID in table CRCO & get values of KOKRS & KOSTL. That value will be unique for an work center But if ARBID values are many for an AUFNR(order no.) that mean you are using different work center where in may be you are using different cost center(i think controlling area will remain same). & hence SAP creates different records.

By using package and fetch from BSEG table. gathering all other information to a final internal table.This will reduce the hit to database.And also try to put that data in hashed internal table which is it_bseg....then definetly improve the performance.

Select query taking too much time to fetch data from pool table a005

Dear all,
I am using 2 pool table a005 and a006 in my program. I am using select query to fetch data from these table. i.e. example is mentioned below.
select * from a005 into table t_a005 for all entries in it_itab
                   where vkorg in s_vkorg
                   and     matnr in s_matnr
                   and     aplp   in s_aplp
                   and     kmunh = it_itab-kmunh.
here i can't create index also as tables are pool table...If there is any solutions , than please help me for same..
Thanks ,

it would be helpful to know what other fields are in the internal table you are using for the FOR ALL ENTRIES.
In general, you should code the order of your fields in the select in the same order as they appear in the database. If you do not have the top key field, then the entire database is read. If it's large then it's going to take a lot of time. The more key fields from the beginning of the structure that you can supply at faster the retrieval.

Performance Issue - Fetching latest date from a507 table

Hi All,
I am fetching data from A507 table for material and batch combination. I want to fetch the latest record based on the value of field DATBI. I have written the code as follows. But in the select query its taking more time. I dont want to write any condition in where claue for DATBI field because I have already tried with that option.
SELECT kschl
           matnr
           charg
           datbi
           knumh
    FROM a507
    INTO TABLE it_a507
    FOR ALL ENTRIES IN lit_mch1
    WHERE kschl = 'ZMRP'
    AND   matnr = lit_mch1-matnr
    AND   charg = lit_mch1-charg.
SORT it_a507 BY kschl matnr charg datbi DESCENDING.
DELETE ADJACENT DUPLICATES FROM it_a507 COMPARING kschl matnr charg.

Hi,
These kind of tables will be storing large volumes of data. Thus while making a select on it, its important to use as many primary key fields as possible in the where condition. Here you can try mentioning KAPPL since its specific to a requirement. If its for purchasing use 'M' and try.
if not lit_mch1[] is initial.
SELECT kschl
matnr
charg
datbi
knumh
FROM a507
INTO TABLE it_a507
FOR ALL ENTRIES IN lit_mch1
WHERE kappl = 'M'
AND kschl = 'ZMRP'
AND matnr = lit_mch1-matnr
AND charg = lit_mch1-charg.
endif.
SORT it_a507 BY kschl matnr charg datbi DESCENDING.
DELETE ADJACENT DUPLICATES FROM it_a507 COMPARING kschl matnr charg.
This should considerably increase the performance

Generic datasource by function module to fetch data from multiple tables?

I'm writing a function module to fetch price, for generic datasource.
At first, extract test is OK. But InfoPackage never stop when loading data to PSA in BW.
And I find the example codes:
     OPEN CURSOR WITH HOLD S_CURSOR FOR
      SELECT (S_S_IF-T_FIELDS) FROM SFLIGHT
                               WHERE CARRID IN L_R_CARRID AND
                                     CONNID IN L_R_CONNID.
    ENDIF.                             "First data package ?
* Fetch records into interface table.
*   named E_T_'Name of extract structure'.
    FETCH NEXT CURSOR S_CURSOR
               APPENDING CORRESPONDING FIELDS
               OF TABLE E_T_DATA
               PACKAGE SIZE S_S_IF-MAXSIZE.
    IF SY-SUBRC <> 0.
      CLOSE CURSOR S_CURSOR.
      RAISE NO_MORE_DATA.
    ENDIF.
    S_COUNTER_DATAPAKID = S_COUNTER_DATAPAKID + 1.
ENDIF.
There using Cursor to fetch data package by package, and raise exception NO_MORE_DATA to stop the loading process.
Now I fetch data from multiple tables, I don't think I can use Cursor.
Then How can I handle this?
Thanks a lot.

How to fetch the data from databse table and get the required output

Hi,
I have made a project that connects CEP to database table but i m getting some problem in fetching the data from database.
From the following code :
If the where condition is removed then the application runs fine but i am still not able to fetch the data from the table because it is not showing any output.
Can anyone please suggest me that how to write WHERE statement correctly and how i will be able to see the output.
Following is the config.xml for processor:

Kindly let me know if you need further info.

Do you have StockDs configured in your server config.xml?
I think the query should look more like this:
SELECT stocks.SYMBOL, stocks.EXCHANGE
FROM STOCK as stocks, ExchangeStream [Now] as datastream WHERE stocks.SYMBOL = datastream.SYMBOL
