Fetching data from multiple datasources

Hi,
I want to fetch data from different datasources to a single cube.
What would be the pre-requisites for carriying out the activity.
Awaiting kind advise.
Thanks

Hi
There r no prerequisites to your requirement . How ever we have different data flows for your requirement as 1. multiple data source to different info sources or transformations to a single cube 2. multiple data sources to single info source or transformation to a single info cube . Any way regarding data flow complexity , second approach is easier one ......
Thanks.

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.

Thanks

Filters on non-conforming dimensions when fetching data from multiple facts

Hi,
I would like to confirm my understanding about how OBI fetches data from multiple facts. I have set up the BMM layer. Through Answers I am getting data from multiple facts as expected. However, is it necessary to base filters only on the conforming dimensions? If I do so, I am getting the correct data. But if I filter data on non-conforming dimensions, then I am getting more data which I am not expecting.
Suppose, Fact1, Fact2 and Fact3 share a CommonDim dimension. If I have a filter on CommonDim, then the filter is used on the three fact tables. However, if I filter data based on Fact1's DimTwo which is not shared by Fact2 and Fact3 and I have measurements from all the fact tables, then from the SQL generated, it seems that OBI is fecting all data from Fact2 and Fact3 and data from Fact1 where DimTwo = 'SomeValue'. Then it seems to be merging the data from the three result sets.
Is this expected, esp. a scenario where a filter is based on a non-conforming dimension (DimTwo in the example)? Have I missed anything? What do I need to do, if I want to return rows from Fact1 based on DimTwo's filter and then if there is data on Fact2 and Fact3 based on the value in CommonDim corresponding to DimTwo's filter?
Please let me know.
Thanks and regards,
Manoj.
PS.: I have got a link now which is http://obibb.wordpress.com/2010/06/06/multiple-fact-reporting-on-non-conforming-dimensions-part-ii/
Edited by: mandix on 25-Oct-2011 12:01

Hi
The problem you describe is similar to mine (I wrote several threads ago).
That is, if there is a non-conformed dimension in a report then the column from the fact table which is not connected with those non-conformed dimensions containes zeros or blanks.
Was this problem solved? I didn't quite catch one of previuos messages... If you can please repeat it more detailed.
What I tried to do is to set Total level in the Content tab (LTS properties). In this example - I could set Total level to JOBS in the plan type dimension. But it didn't help.
So if you know what to do then please describe it here...

Fetching Data from Multiple Services or End Applications in BPEL

Hi,
We do have a requirement of fetching the data from multiple services exposed by the end applications. And there are no inter dependencies among these.
Mostly 6 to 10 partner links have to be used to fetch this data. So planning to use the flow N activity to achieve this.
But i did come across a best practice to avoid the use o Flow N activity with number of lines. So i wanted to know pros and cons of this approach and i there is any better way of doing the same in BPEL.
We are using SOA Suite 11.1.1.4.0.
Thanks

To fetch Data from multiple database tables!

How to fetch Data from fields of multiple database tables!
Give me one example!

use <b>join....</b>
c the SAPHELP docs...
FROM tabref1 [INNER] JOIN tabref2 ON cond
Effect
The data is to be selected from transparent database tables and/or views determined by tabref1 and tabref2. tabref1 and tabref2 each have the same form as in variant 1 or are themselves Join expressions. The keyword INNER does not have to be specified. The database tables or views determined by tabref1 and tabref2 must be recognized by the ABAP Dictionary.
In a relational data structure, it is quite normal for data that belongs together to be split up across several tables to help the process of standardization (see relational databases). To regroup this information into a database query, you can link tables using the join command. This formulates conditions for the columns in the tables involved. The inner join contains all combinations of lines from the database table determined by tabref1 with lines from the table determined by tabref2, whose values together meet the logical condition (join condition) specified using ON>cond.
Inner join between table 1 and table 2, where column D in both tables in the join condition is set the same:
Table 1                      Table 2
A
B
C

    | a4 | b4 | c4 | 3 | 3 | e2 | f2 | g2 | h2 |
    |--||||||||--|
Example
Output a list of all flights from Frankfurt to New York between September 10th and 20th, 2001 that are not sold out:
DATA: DATE   LIKE SFLIGHT-FLDATE,
      CARRID LIKE SFLIGHT-CARRID,
      CONNID LIKE SFLIGHT-CONNID.
SELECT FCARRID FCONNID F~FLDATE
    INTO (CARRID, CONNID, DATE)
    FROM SFLIGHT AS F INNER JOIN SPFLI AS P
           ON FCARRID = PCARRID AND
              FCONNID = PCONNID
    WHERE P~CITYFROM = 'FRANKFURT'
      AND P~CITYTO   = 'NEW YORK'
      AND F~FLDATE BETWEEN '20010910' AND '20010920'
      AND FSEATSOCC < FSEATSMAX.
WRITE: / DATE, CARRID, CONNID.
ENDSELECT.
If there are columns with the same name in both tables, you must distinguish between them by prefixing the field descriptor with the table name or a table alias.

Fetch data from multiple cubes...help

Hello,
this is the very first time I post in this forum. I am using EssBase and now Smartview since about one year getting simple retrieves from cubes. One sheet for each cube I need.
Now I would like to merge two sheet that are based on different cubes and I am thinking to use only one sheet to fetch data from the two cubes. I think I have to define multiple grids but I'm not sure if it so.
Can you suggest me some useful link or tutorial where I could find more info about it? I am really new with this.
thank you, your help will be really appreciated.
ciao

Hi,
Welcome to the forums!
This document will show you how to define multiple grids: Page 55

Extracting data from multiple datasources through DAC

We have to extract data from two Oracle datasources (GL datasource 1 and GL datasource 2) by DAC client to one Datawarehouse. We have configured DAC for one datasource and it is working fine. How can we add another datasource into the same DAC client.
Neeraj

You will need to update the Source DB connections in both the DAC and Informatica Workflow before you want to load the DW with the other GL Database. You will contnuously have to switch these configuration settings or stand up another DAC Server, Repository and Client that point to the same Datawarehouse.

Fetch data from multiple tables

Helo all,
I am having four tables in database which are independent having no relations and all columns are different in each table.
I wants to create Sp where all data can be fetched at once where there is something to differntiate that Ok this data is of this table and so on...
so that from server side code i have to hit database only once and from output i will assign tables to their array.
Is there any way to do so ??
Niki

Hi Nikijain,
Since your requirement is not precise so I have to guess you may be looking for a sample as below.
CREATE TABLE T1(ID INT);
INSERT INTO T1 SELECT 1;
GO
CREATE TABLE T2(ID INT);
INSERT INTO T2 SELECT 2;
GO
CREATE TABLE T3(ID INT);
INSERT INTO T3 SELECT 3;
GO
CREATE TABLE T4(ID INT);
INSERT INTO T4 SELECT 4;
GO
CREATE PROC p4test
AS
SELECT ID FROM T1;
SELECT ID FROM T2;
SELECT ID FROM T3;
SELECT ID FROM T4;
GO
EXEC p4test
DROP TABLE T1,T2,T3,T4
DROP PROC p4test
Regarding how to access the resultset individually, you may reference the below links.

How to fetch data from multiple fact tables from a normalized schema?

Hello everybody,
I am working on a normalized schema to build my repository. I have categorized the tables into dimensions and facts. I have 3 fact tables in my schema and they have a 1:m:1 relationship i.e. if I have table A, B, and C; A has 1:m relationship with B and C also has 1:m relationship with B. How can I use measures from these tables to create a star schema. If A = Sales, B = Transaction, C = Payment_Amount
Sales(Sales ID, Amount, Tax pct, ...)
Transaction(Transaction ID, Sales ID, Payment ID,Transaction Amt, ...)
Payment_Amount(Payment ID, Check ID, Payment Made, ...)
Please give me some direction to pursue.
Thank you!

Data Upload from Multiple DataSource

Hi All,
How can i upload data from multiple datasources to a single Cube in BI 7??
Kindly provide step by step procedure.
Regards.

Hi,
In BI 7 you still have both data flows present, You can either use the old 3.5 dataflow or the new BI 7 dataflow.
SAP has still allowed organizations to use the old 3.5 dataflow till they convert over to the newer flows so that the production dosen't disturb. Its takes some efforts to convert the 3.5 data flows to the 7.0 flows.
So, the way its usually done is, a technical upgrade is done. Then existing modules are converted over to the 7.0 dataflows in a phased manner. Any newer projects that come along are carried out with the 7.0 functionality.
Even if you install business content in a 7.0 system, you'll get 3.5 objects. You need to convert them over to the 7.0 versions.
Cheers,
Kedar

Move data from multiple Tables to a Single Table & Convert the list to ALV.

Change like this,
SELECT matnr
lgort
labst FROM mard
INTO CORRESPONDING FIELDS OF TABLE i_mard
FOR ALL ENTRIES IN i_marc
WHERE matnr = i_marc-matnr.
LOOP AT i_mard.
   WRITE: /10 i_mard-matnr,
   30 i_mard-lgort,
   40 i_mard-labst.
ENDLOOP.
LOOP AT i_marc.
   READ TABLE i_mard WITH KEY matnr = i_marc-matnr.
   READ TABLE i_makt WITH KEY matnr = i_marc-matnr.
   MOVE i_mard-matnr TO i_final-matnr.
   MOVE i_marc-dispo TO i_final-dispo.
   MOVE i_marc-minbe TO i_final-minbe.
   MOVE i_makt-maktx TO i_final-maktx.
   MOVE i_mard-labst TO i_final-labst.
   APPEND i_final.
ENDLOOP.

Multiple select queries used in Excel BI report ,fetching data from Sharepoint DB(SP2010_Prod_ProjectServer) causing blockage on DB ,when more than one workbook(same copy of Excel BI Report) refreshed using Refresh All option.

is being fetched in secs. but when more than one copy of same Excel BI report is refreshed using 'Refresh All' option, then these select queries cause blockage on DB.
Please let me know mitigation for this blockage issue.
Should I use begin transaction and commit transaction statements/ shared lock statements.

Business components from multiple datasources

Hi All,
I want to create business components from multiple datasource. Please tell me if it is possible in ADF framework and Jdeveloper 11.1.1.4
I opened the Model.jpx and tried adding the two datasource but it is showing as a dropdown list from which I can choose only one.
My requirement is to have components from one datasource and read data from a second database to create a LOV
Please suggest how to go about it
Thanks

Hi,
There are many ways to achieve this.
If your requirement is just to read data from different database (and not to update it), then using a database link would be a better approach.
You could create a database link in the primary database (target database being the one you would like to query). Base your sql query for the vo using the db link.
