Hi,
You could use Openhub

Extraction, Flat File, Generic Data Source, Delta Initialization

Extraction, Flat File, Generic Data Source, Delta Initialization
I have couple of questions regarding data extraction.
1.     If you have Data Source a Flat File e.g. Excel file I know that you have to create Data Source at BW side. How do you upload updates, by selecting Delta Update when executing next Data Load? Do you ever u201Cconvertu201D this Excel file into Application Tables to become SAP Source 
2.     Can you please give me example of situation where you had to create Generic Data Source? What is difference between Time Stamp, Calend. Day and Numeric Pointer. Which one is most common to select?
3.     I read somewhere that Generic Data Source does not have Setup Table. I thought that you have to have Setup Table in order to load transaction Data otherwise you will lock the Application Tables. Where am I going wrong im my thinking please?
4.     What are steps in terms of IP before, under and after Delta Initialization. I belive that you can do two ways:
Full Update - Initialize Delta Process (without Data Transfer) u2013 Delta Update or
Initialize Delta Process (with Data Transfer) u2013 Delta Update
Am I right? What is most common method and why?
5.     If you want to add a filed in Data Source after 6 month using it, you want to do it without re-init Delta Queue. You add field in RSA6, then provide info for ABAP to populate new filed (info u2013 name of Data Source, Extract Structure, field added, name of Application Table which contains the field). How does it work now as there is no SetUp table it has been deleted after Initialisation? How does Delta Queue know that it is going to receive data which has been expanded by one field or it may does not need to know at all?
THANKSSSSSSSSSs

Hi,
1. If you have Data Source a Flat File e.g. Excel file I know that you have to create Data Source at BW side. How do you upload updates, by selecting Delta Update when executing next Data Load? Do you ever u201Cconvertu201D this Excel file into Application Tables to become SAP Source
Once you create Datasource for A flat file extraction then it is file source system specific hence you cont change to Application table source Data source
In info package you can change the source as application server instead of desktop no need to change the DS
2. Can you please give me example of situation where you had to create Generic Data Source? What is difference between Time Stamp, Calend. Day and Numeric Pointer. Which one is most common to select?
When we don't find any standard extractor then we can go for Generic(if i want information sales along with finance information in a data source then generally we dont get standard one hence we can go for generic DS)
Check the below link for More about generic DS .
http://wiki.sdn.sap.com/wiki/display/BI/Generic+Extraction
for Delta capturing you can use
Timestamp(if the table has time stamp filed so it can stamp the last changed record in that table hence it is easy to get delta based on the time stamp)
Calday- (If the table doesn't have the Timestamp filed then search for Calday where you can stamp the delta based on the date when documents are changed )
Numericpointer : If the table doesn't above both then we go for this option where you can the numeric value change stamp )
3. I read somewhere that Generic Data Source does not have Setup Table. I thought that you have to have Setup Table in order to load transaction Data otherwise you will lock the Application Tables. Where am I going wrong im my thinking please?
Generic datasource nothing but we extracting data directly from the database table without any interface between the application/systems
4. What are steps in terms of IP before, under and after Delta Initialization. I belive that you can do two ways:
Full Update - Initialize Delta Process (without Data Transfer) u2013 Delta Update or
Initialize Delta Process (with Data Transfer) u2013 Delta Update
Am I right? What is most common method and why?
Correct
5. If you want to add a filed in Data Source after 6 month using it, you want to do it without re-init Delta Queue. You add field in RSA6, then provide info for ABAP to populate new filed (info u2013 name of Data Source, Extract Structure, field added, name of Application Table which contains the field). How does it work now as there is no SetUp table it has been deleted after Initialisation? How does Delta Queue know that it is going to receive data which has been expanded by one field or it may does not need to know at all?
Once you add the new field to structure(DS) you will get the data as on date onwards not historical data hence what is the concept of setup table ( delta records come from the Delta Que not from the setup table )
If you want histaric data to new field then you need to setp table deletion ...etc...
Hope it is clear..

A question on ETL on flat file folder

Hi,all, I am a student currently exploring Oracle Technologies.
I used to use Microsoft SQL Server Integration/Analysis/Reporting Services. Wanted to achieve something like this too, using oracle.
Had done some simple tutorial on owb for a day, I briefly understand the basics.
Q:
However, all the tutorial taught me on flat files was a single individual flat file, if I want to perform extraction on ALL the flat files in a particular folder, is this possible with OWB?
Thank a lot!.

yes, its available now, trying to learn it, thank guys.
Another question: that I was pondering over about:
I was always wondering what will happen to the data in table if I were to run the ETL process flow twice, what actually happens to the previous existing data?
extra:
What I was planning to do is, I have a folder is populated with new flat files everyday, I only want to extract these datas once and have them in the Cube/Fact table for analysis.
Question is, do I have to move extracted flat files to another directory after process flow such that next time the process flow wont extract these flat files again?

BI 700 - How to preview flat files in an Infopackage

HI Friends,
Just another cry for help _
When extracting flat files, tab 'External Data' of Infopackage provided the option to preview data and to adjust
seperators for decimals and thosuands in BW 3.5. I'm missing this in BI 700. The place I found to adjsut this, is the datasource.,
That means, I've to transport all changes. Is this really the only way?
Please help.
W are on SP21 and GUI Patch 14.
Thanks in Advance
Joe

Hi Pratap & RK,
you're completely right, there is always a workaround, but in the past I had just tp press one button
for receiving my information required, and I'm just not able to understand why somebody removes it (from 3. to 700).
And until we impemenetd BI 700 my understanding purpose of releasing a new software version should be progress and not
regress. It should make work faster and easier. So far my philosopy....
@RK Due to our system settings change of a Da is not allowed in Prod, so I can only preview file defined in
DEV of tarsnported DS.
Thanks and Regards
Joe

InfoSpoke Flat File Extract to Logical Filename

I'm trying to extract data from an ODS to a flat file. So far, I've found that the InfoSpoke must write to the application server for large data volume. Also, in order for the InfoSpoke to transport properly, I must use logical filenames. I've attempted to implement the custom class and append structure as defined in the SAP document "How To... Extract Data with OPEN HUB to a Customer Defined Logical Filename". I'm getting an error when attempting to import the included transports (custom class code). It appears to be a syntax error. Has anyone encountered this, and, if so, how did you fix it?

Hello.
I'm getting a syntax error also. I did not import the transport, but applied the notes thru the appendix. When I modified the method "GET_OBJECT_REF_INT" in class CL_RSB_DEST as below, I get a syntax error on the "create object" statement.
    when rsbo_c_desttype_int-file_applsrv.
*{   REPLACE        &$&$&$&$                                          1
*\      data: l_r_file_applsrv type ref to cl_rsb_file_applsrv.
      data: l_r_file_applsrv type ref to zcl_rsb_file_logical.
*}   REPLACE
      create object l_r_file_applsrv
        exporting i_dest    = n_dest
                  i_objvers = i_objvers
Class CL_RSB_DEST,Method GET_OBJECT_REF_INT
The obligatory parameter "I_S_VDEST" had no value assigned to it.

One Time Flat File load in a Cube that extracts from ECC

Hi,
I have a cube that is already extracting data from ECC on a daily basis. I am asked to load some historical data into the cube from their legacy system. My question is, how do i prepare that file from the legacy system to match the fields in the Cube? What are the technicalities that i need to look at?
For Example:
0MATERIAL in the Cube: Material Number in the Flat File
ZAMOUNT in the Cube: Cost of Product in the Flat File
How do I arrange to match these?
Thanks

Hi
Create DS and enter the required objects
Preview the Data
Create Transformations (Map DS fields to Targets Objects - direct assignemnt)
Create Infopack and extract data upto PSA
Create DTP and run - it will extract data from PSA to Target
No of Heade rows to be ignored : 1
File type : CSV
Data seperator : ;
Escape Sign: "

Extracting data from Oracle to a flat file

I'm looking for options to extract data a table or view at a time to a text file. Short of writing the SQL to do it, are there any other ideas? I'm dealing with large volumes of data, and would like a bulk copy routine.
Thanks in advance for your help.

Is there any script which i can use for pulling data from tables to a flat file and then import that data to other DB'sFlat file is adequate only from VARCHAR2, NUMBER, & DATA datatypes.
Other datatypes present a challenge within text file.
A more robust solution is to use export/import to move data between Oracle DBs.

Extracting XML Data to a flat file

I have an application which is puting an XML string into a field in the database... now my problem is that I have to extract that information and put it in either 1. a flat file, or 2. a seperate table containing a column for each XML attribute... Does anyone know of the best way to approach either solution?
cheers.

And your Oracle version is?
There are many different ways to put something into a file. How about UTL_FILE?http://www.psoug.org/reference/utl_file.html
How to get it out of the table in the first place?
I usually try a SELECT statement. They seem to work.
PS: Databases don't have fields ... table's don't either. Check your verbiage.
Try looking of the word "FIELD" in the Oracle docs. Then try "COLUMN."

Query extraction to a flat file

We have a requirement to extract the query result and send it as a flat file to a different system. The query is created on a multi provider and the key figures have lot of restrictions. We currently use RSCRM_BAPI for this. Would like to know if there is a better options, if any one has used it.
Thanks,

How to extract required data from a column to a flat file

my ssis package is working OK. However, I want to refine one of the column extraction.
when data is extracted to the flat file, I just want to the initials, firstname, lastname e.g.
FZ = Ben Smith, Add1, add1, etc
the only bit that i want is Ben Smith
how can i state in the package to just give me the name and exclude the rest
sukai

Add a derived column task to extract Name part alone and give expression as below
LEFT([ColumnName],FINDSTRING([ColumnName],",",1)-1)
If before SSIS 2012 use SUBSTRING
SUBSTRING([ColumnName],1,FINDSTRING([ColumnName],",",1)-1)
Please Mark This As Answer if it helps to solve the issue Visakh ---------------------------- http://visakhm.blogspot.com/ https://www.facebook.com/VmBlogs

How to Extract data to a Flat File?

Hello,
Im using OWB 10g and Oracle 9.2 version of database. I want to know the complete steps of creating the flat file as my target module. I need to extract the data (source) from the oracle tables and load it into the flat files. Pls let me know your suggestions. Pls note except the flat files, I do not have any oracle tables as my targets.
Thanks,
Kishan

Hi, here's an excerpt from some notes I wrote a few months ago, they shpoud be clear enough.
0) the file will be created on the server using the utl_file package. So the path where the file will be created must be added to the utl_file_dir Oracle Server parameter. Request your DBA to complete this step.
-In OWB client:
1) create a file location (or use existing one) under "Files/Locations" in project tree
2) create a new Flat File module (or use existing one) under "Files" ; associate it with the desired location (not really necessary)
3) create a new mapping in an Oracle module
4) add to mapping a table operator bound to the table to dump
5) add to mapping un unbound Flat File (FF) Operator, give it a meaningful name
6) drag the desired attributes from table to FF Operator. This will instruct OWB to feed the file with comma-separated values from the source table using the utl_file package. Be careful to format attributes accordingly to the format you want.
7) reconcile outbound the FF Operator, creating a new flat file in the module created during step 2
8) close mapping, right-click on it an from menu "Configure..."->"Sources&Targets"-><YOURTARGETFILE>, specify the desired output location and the output file name
9) Open deployment manager and connect to runtime rep. If the FF location is new, register it by right-clicking+menu "Register" and specify parameters: operating system user/passawrd of the DB server, host and path where the file will be stored (must be the same added to utl_file_dir). ATTENTION: path info is stored in the generated mapping so be sure to redeploy mappings if changes occur
10) deploy mapping, test execution
11) OPTIONAL you can specify a different delimiter (TAB,etc) for the target file directly in its editor. But be careful then to reconcile inbound the FF op in the mapping before deploying.
Cheers, Antonio

Error Extracting Essbase Product Dimension to a Flat File

I am new to ODI and do not know how to troubleshoot this issue.
I am trying to extract an Essbase Dimension (Product) to a Flat File.
The source is Essbase Product and the Flat File is the Target. The target file is .csv.
I have the fields to execute on Staging Area.
When I click apply, I get an error stating: Target/Staging Area: You must set a IKM for the target.
In the IKM folder I have the following:
IKM SQL to File Append
IKM SQL Hyperion Essbase (DATA)
IKM SQL Hyperion Essbase (METADATA)
I appreciate any help you can offer.

Follow this and you should be able to get an interface to extract metadata from essbase - http://john-goodwin.blogspot.com/2008/10/odi-series-essbase-outline-extractor.html

Extract BW infocube data to a flat file

Hi Folks,
I have a requirement where I need to extract data from Infocubes to a flat file.
Please suggest me the ABAP programming methodology where i can use function module to extract data from cube and dump it to internal table.
Your immediate help is required.
Thanks,
Rahul

you can simply try a workaround for your problem
right click on cube -> display data-> menu bar->edit--download->save as spreadsheet (.xls) and extract the data
and if you want .txt only. try saving excel in .csv then you can open that via notepad and save it in .txt
you wil be saved frm writing abap codes

Extract data from Query to a Flat File - scheduling in the background

Hi All,
We need to extract data from a query to a flat file periodically, but each time 10 separate executions based on 10 profit centers, to get the separate files.
So, we have PC1, PC2, ... PC10 Profit centeres.
We have Query1, with profit center variable.
We have created 10 variants for Query1 so that we can execute for 10 profit centers.
Now, we have used RSCRM_BAPI to execute the Query1 and write to a flat file. Now we are having a problem in getting this feature used to execute the query automatically for 10 different varaints.
Thanks in advance,
_ Shashi

Shashi,
You can try using Information Broadcasting or Reporting Agent. You can schedule this in Information Broadcasting.

Infocube data extract to a flat file

Hi,
I have a requirement to extract data from a infocube into a flat file and send it to a 3rd party. The data in infocube is coming from erp and another 3rd party system. This combined data in inficube needs to be extracted and send to another 3rd party system in a flat file system. Is there any generic function module that can be used or I have to extract from underlying tables directly. Pl. let me know your experiences.
Thanks,
Jassi.
