[b]How to improve data retrival from a table?[/b]

Hi,
I have table with 600 million records having 8 fields and containing 30 days data.
The table is partitioned with 10 segments. Each segments having equal updates or deletion.
The table is indexed with a time field.
While I am using a query to retrieve data for 14 days it takes around 9 hours(I was not using any order by or group by key word) by using the time field index.
Could you please suggest any methods to improve the data retrieval?
Thanks in advance

Hi,
You have data of 30 days, from them you want to retive 14 days, which is about 50% or 300M Rows. Why would you use an index to do that? A FTS would probably be much faster.
Also could you please show the query itsel as well as the explain plan.

Hi theresita,
i would like to retreive payroll results from it's allocated cluster tables .
1. U want the remuneration (monthly salary )
2. U won't get it DIRECTLY from any table.
(Its stored in cluster format)
3. Use this logic and FM.
DATA: myseqnr LIKE hrpy_rgdir-seqnr.
DATA : mypy TYPE payin_result.
DATA : myrt LIKE TABLE OF pc207 WITH HEADER LINE.
SELECT SINGLE seqnr FROM hrpy_rgdir
INTO myseqnr
WHERE pernr = mypernr
AND fpper = '200409'
AND srtza = 'A'.
IF sy-subrc = 0.
CALL FUNCTION 'PYXX_READ_PAYROLL_RESULT'
EXPORTING
clusterid = 'IN'
employeenumber = mypernr
sequencenumber = myseqnr
CHANGING
payroll_result = mypy
EXCEPTIONS
illegal_isocode_or_clusterid = 1

OTHERS = 10.
myrt[] = mypy-inter-rt.
READ TABLE myrt WITH KEY lgart = '1899'.
4. the internal table myrt
will contain what u require.
I dont think there is any buffering concept
involved in cluster table.

How to creat   individual Datasource for   1.Finance & Payemnt Mis , 2. Inventory, 3. Invoices, 4. Taxation , 5. Mater data. ?

Hi,
Go for the generic data sources.
1. first create the view on all the tables.
        You can only use join conditions but not Union.
        you can specify one table as primary table based on your requirement.
2. build the data source based on the view.

Hi,
You can get it from "User" or "Shop" business object.
Try to get User or Shop Business Object as shown below.
BusinessObjectManager bom = (BusinessObjectManager) userSessionData.getBOM(BusinessObjectManager.ISACORE_BOM);
User user = bom.getUser();
char decimalNotation = user.getDecimalPointFormat().getGroupingSeparator();
If you are seeing "1,234.00" then above code will return "."
I hope this information help you to resolve your issue.

How to make data flow from one application to other in BPEL.

Hi All,
I am designing work-flow of my application through BPEL(JDeveloper), I am making different BPEL projects for different functions, like sales manager got the order from sales person and sales manager either approve it or reject it, if he approve it it goes to Production manager and he ships the goods, now I want to keep sales person, sales manger,production manager in seperate BPEL files and want to get the output of sales person to sales manager and sales manager to production manager please help me in dong this.
I was trying to make partner link in Sales manager of sales person and getting the input from there. I dont know this is right even or not, if it is right I dont know how to make data flow from one application to other.
Experience people please guide.
Sales Person -----> Sales Manager ----> Production Manager
Thanks
Yatan

Yes you can do this.
If you each integration point to be in different process, you have to create three BPEL process.
1. Create a Async BPEL process 'A' which will be initiated when sales person creates the order.
2. From BPEL process 'A' call a ASync BPEL process 'B' which has the approval flow. Depending on the input from process 'A' the sales manager will review the order in workflow and approve or reject and send the result back to process 'A'.
3. Based on the result from workflow, invoke the Sync BPEL process 'C', where you can implement the shipping logic.

how to restore data file from back up on iPhone 5 docs to go

If it backed up the lock file, then Lightroom was open when Time Machine ran, and the backup therefore may be corrupted. You could try restoring that backup (without overwriting your week ago version) and see if it'll open. If it does, you're off and running. What methods have you tried?

How to retrieve the values from a table if they differ in Unit of Measure

How to retrieve the values from a table if they differ in Unit of Measure?

If no data is read
- Insure that you use internal code in SELECT statement, check via SE16 desactivating conversion exit on table T006A. ([ref|http://help.sap.com/saphelp_nw70/helpdata/en/2a/fa0122493111d182b70000e829fbfe/frameset.htm])
If no quanity in result internal table
- There is no adqntp field in the internal table, so no quantity is copied in itab ([ref|http://help.sap.com /abapdocu_70/en/ABAPINTO_CLAUSE.htm#&ABAP_ALTERNATIVE_1@1@]).
- - Remove the CORRESPONDING, so quantity will fill the first field adqntp1. ([ref|http://help.sap.com/abapdocu_70/en/ABENOPEN_SQL_WA.htm])
- - Then loop at the internal table and move the quantity when necessary to the 2 other fields.
* Fill the internal table
SELECT msehi adqntp
INTO TABLE internal table
FROM lipso2
WHERE vbeln = wrk_doc1
    AND msehi IN ('KL','K15','MT').
* If required move the read quantity in the appropriate column.
LOOP AT internal_table ASSIGNING <fs>.
CASE <fs>-msehi.
    WHEN 'K15'.
      <fs>-adqnt2 = <fs>-adqnt1.
      CLEAR <fs>-adqnt1.
    WHEN 'MT'.
      <fs>-adqnt3 = <fs>-adqnt1.
      CLEAR <fs>-adqnt1.
ENDCASE.
ENDLOOP.
- You could also create another table with only fields msehi and adqntp and then collect ([ref|http://help.sap.com/abapdocu_70/en/ABAPCOLLECT.htm]) the data to another table.

How to do a SELECT from different tables into an internal table?

How to do a SELECT from different tables into an internal table?
I want to select data from MARA, MARC and ZPERSON and populate my ITAB_FINAL
REPORT zinternal_table.
TABLES:
mara,
marc,
zperson.
TYPES:
BEGIN OF str_table1,
v_name LIKE zperson-zname,
v_matnr LIKE marc-matnr,
v_emarc LIKE marc-emarc,
v_werks_d LIKE marc-werks_d,
v_dstat LIKE marc-dstat,
END OF str_table,
i_table1 TYPE STANDARD TABLE OF str_table1.
DATA:
BEGIN OF str_table2,
v_mandt LIKE mara-mandt,
v_ernam LIKE mara-ernam,
v_laeda LIKE mara-laeda,
END OF str_table2,
itab_final LIKE STANDARD TABLE OF str_table2.

first find the link between mara , marc and zperson , if u have link to 3 tables then u can jus write a join and populate the table u want ( thats final table with all the fields).
u defenitely have alink between mara and marc so join them and retrieve all data into one internal table.
then for all the entries in that internal table retrieve data from zperson into another internal table.
then loop at one internal table
read another internal table where key equals in both the tables.
finally assign fileds if sy-subrc = 0.
gs_finaltable-matnr = gs_table-matnr
etc...
and finally append gs_finaltable to gt_finaltable.
there u go ur final table has all the data u want.

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).
