Creating Datasource and Extracting from SAP R/3 ECC 6.0

Hello Gurus,
I am very new in BI field, I am learning through notes provided in this Blog.
Curretnly I need to know how we create Datasource at SAP R/3 ECC 6.0 (is there any difference b/t these?)
and how we may extract data from R/3 ECC 6.0 Source System.
Looking for your kind reply
Thanks in Advance
KK

You can use any specific Extractors to Create Data Source in R/3 side.
Let me explain with Generic Extraction
Goto SBIW--> you can see all the extractions here
Generic extractors are of 3 types:
1. Based on table/view
2. Based on Info set Query
3. Based on Function module
If you would like to create a custom table, then goto SE11>Select Table>Click on Create (Now create you own table here & use this table while creating Transaction data)
Goto RS02-->Select Transaction data.
Click on Create
Choose an application component to which the data source is to be assigned
Click on Generic Delta
Specify the Delta-Specific and the type for the field.
Specify a safety interval
Select Data type>Save> Now Data source was generated successfully
After generating the data source , you will find Delta Flag checked.
Please go through the following link for Generic Delta
[https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/84bf4d68-0601-0010-13b5-b062adbb3e33]
Once you've done with Data Source in R/3 side--> u need to Replicate it to BI
Goto RSA1>source system>Select the Source system in which u've created Data source>R.C select Data Source Overview>Select the Application Component to which Data source is assigned>R.C Select Replicate dataSorce>here you can see your NEW Data source
Hope it helps!

Extraction from SAP ECC to SAP BI

What are the steps for Extraction from SAP ECC to SAP BI? Thanks.

Hi,
we have two types of extractions 1) Application specific 2)cross application
under applicatin specific -->we have customer genenrated and business content extractions
under customer generated means LIS, CO-PA, FI-SL(i.e no ready made data source in business content so we have to generate datasource)
Business content means there is ready made business content datasource so we can use it
LIS,LO --> when ever we go for extracting logistics informatin

Generic extraction-->table, view, infoset query, function module
Generic extractors are of 3 types:
1. Based on table/view
2. Based on Infoset Query
3. Based on Function module
GenericSteps
Log on sap R/3.
Step 1. create a table or view for generic extraction in se11.
Step 2. Goto t-code RSO2
Step 3. Here u have to decide whether to extract transaction data or master data attributes or texts.
Step 4. suppose if u have opted for transaction data,then give name in the column ex:ztd_m(data source name)
Step 5. select create button,this will take u to another screen.
Step 6. Here u have to decide from which application component u r extacting data.Ex: SD,MM,..
Step 7. in this screen u have to fill short disciption,medium,long( these r mandatory).
Step 8. then U have to Table name or view name which u have created in se11.
Step 9. I f u want to maintain generic delta then u can select generic delta in top left hand side corner.
Step 10. in next screen u have to give some field which is primary key.
step 11. here u to specify whether time stamp or cal day or numeric pointer depending on u r requirement.
step 12. then u have to specify whether new status for changed records or additive delta.
If u choose additive delta ,then u have to load data to infocube or ods object.
If u choose new status for changed records, then u to load data to ods object only.
Step 13. then save it.
Step 14. then logon to sap bw ,then replicate the data source then as usuall.

Data Extraction from SAP R/3 Table View in BW

Dear All,
I am trying to create a BW query from SAP R/3 Table View.
Till now i have created a table view
Extracted Data source in R/3 Useing Tcode : RSA3
In BW Side
1. I have replicated the data source in Source system
2. Created info object
and info object catalog
and assigned it
Now i am little confused over what to do next
wheather to create ODS object in info cube,
Please guide me with rest of steps to follow.
Regards,
Gaurav

Hi,
After replicating DS in BW, you have to maintain ODS or Cube for maintaining data in BW.
After loading data into Data Targets you can create Reports based on those Data Targets.
For better reporting performance you can create Cube rather ODS.
Info Source(After Creating info Objects, you have to create a Transfer Structure to map the Fields.)
Then create a Data Target ODS/Cube.
Update rules

Hope it helps you .
Let us know if you still have any issues.

Master data extraction from SAP ECC

Hi All,
I am a newbie here and teaching myself SAP BI. I have looked through the forums regarding master data extraction from SAP ECC in all forums but could not answers for my question. Please help me out.
I want to extract customer attributes from SAP ECC. i have identified the standard data source 0customer_attr and replicated in SAP BI. I have created infopackage for full update. I validated the extractor checker(RSA3) and found 2 records for 0customer_attr.
When I run the info package, the info package remains in yellow state until it times out. Please let me know in case i am missing anything, Please let me know if there is any other process for master data extraction similar to transaction data extraction.

Hi All,
i did the below and afte clicking execute in the Simple job, it takes me back to the Monitor Infopackage screen.
From your info pack monitor --> menu environment-->job overview--> job in the source system--> prompts for source system(ECC) user id and password, enter them, you will get your job at SM37(ECC), select job and click on log details icon. there you can see details about your error. please share that error screen shot.
Please find the screenshots.

Datasources and Extract structure

Hi guys,
I am pretty confused about DataSources and Extract structure.
Can someone please explain it me in simple words.

Hi Zubin,
Data Source is a consoliated list of fields available and the extract structure is a data dictionary structure which illustrates the fields with additional technical elements like DATA ELEMENT , DOMAIN ans so on...
To make it more clear look at this description from F4 help:
A DataSource is an object for retrieving data. The DataSource is localized in the OLTP system.
It has
an extract structure,
an extraction type, and
an extraction method.
The extract structure describes the fields of the internal table that contain the extracted data. The extraction type describes which type of extractor the DataSource uses. The extraction method extracts the data and transfers it into an internal table with the same type as the extract structure.
The DataSource also contains information on the type of data that it stages, for example, attributes, transactional data, hierachies, or texts. It can also support different types of data update.
Extract Structure for a DataSource
The extraction structure for a data source shows the format in which the DataSource, or the extractor for the DataSource, transfers its data.
A data element must be assigned to each field of the extraction structure. This allows in the Business Information Warehouse an intelligent mapping between field names and InfoObjects using just this data element.
The extract structure must be created in the DDIC as a dictionary structure or transparent table. A view is not permitted here since it would then not give you the option to add an append.
Appends enable you to convert your individual requirements and own "Business Logic" in the extraction process. You can fill the fields in the append using function enhancements.
Hope this helps
Thanks,
Raj

Compare creation of Datasources and JMS Queues : SAP vs (Weblogic/Websphere

I am used to creating JDBC Datasources and JMS Queues on Weblogic/Websphere thru their Admin applications.
Can someone compare/contrast that process to that on SAP's netweaver ( either using NWA or Visual Administrator).
Thanks

Hi Parag,
For the process of creating JDBC datasources and JMS resources @ SAP NetWeaver you can refer to the documents here on SDN and help.sap.com, and compare that process for yourself, thus not being influenced by others' biased or unbiased opinions.
For NetWeaver 04 and 04s these would be:

DataSources and extract structures generation

Hi,
How would I generate the DataSources and extract structures using transaction LBWE? It seems that there are no push buttons to say to generate the DataSources and extract structures from LBWE? Would clicking on the DataSources and extract structures and click on the continue button be enough?
Thanks

I check from LBWE maintenance structure column, and the fields are there on the left hand side for the selection criteria.
How would I check "..fields you have enhaced are ready to use...." from LBWE.
From RSA6, I would doubleclick on the LIS datasource, and I see no enhanced fields and therefore could not see if they are hidden.
"Did you check in LBWE if your strcutures have the fields ready to use?" How would I do this? Maybe this is the problem.
Thanks

Java applets run in a "sandbox" so to speak... so you
can't do this :)
If you really really want to, you can purchase a
license from Verisign, sign your applet and then (try
to) turn off all of the security restrictions in your
applet and then do whatever you want...I believe you can also change the permissions file - on each client.

Creating Logic and modeling for SAP BW datasource in SAP HANA views and SLT

Hi to all,
I have small question.
We have BW system and SAP ECC as source system and to get data from SAP ECC source system we are using SAP ECC Standard data source.
Now we required to, create modeling in SAP HANA by use of HANA View and get data from SAP ECC source table via SLT.
So we can replicate same modeling,as we done in SAP BW system.
But my question is that, as SAP ECC standard data source hit multiple table and do run-time calculation, before sending to SAP BI.
How we can derives such calculation and logic, in our HANA studio, because as we know in SLT data transformation can be done in limited way also
in view we can not drive such logic via SQL script ?.
Is there any way we can do such modeling and logic in SAP HANA ?
or
is there any standard document for this type of case, which we can use ?
Note: We don't want to use SAP DS or DXC for data loading to HANA, as we want it in more real time.
Regards
Pavneet Rana

Thanks for reply,
As SLT is based on ABAP, so we can write complex logic in it.
But if we talk about SAP ECC standard data source, they have complex logic, based on multiple table.
So we need to write code from scratch in SLT to derive same result. but it will be huge time consuming , and required good ABAP skills, also it will lead to bug in code.
Also it will reduce the real time performance of SLT, due to complex logic.
Second option is procedure via SQL script, which is again huge effort in term if logic and can lead to error/bug in logic.
Does we have any other way or architecture to do this is very simple way, with high performance and less error issue.

Extraction from SAP, hidden fields problem

Hi Expeerts,
I have the following problem / question:
From an SAP Datasource (2lis_11_vaitm) we have some fileds, those are HIDED, and we need them. This is a central SAP, and a lot of BW systems connect to this SAP.
The problem is, that we need a field from that datasource (and other BWs do not need), that has 'HIDDEN' option. The SAP side is afraid of having problem, when they just uncheck that option. (TELF1; KONDA fields we need).
Does anyone know, what is the affects on other BW systems, when we unhide this fields? Of course we load with delta from this source.
If a field is hidden in SBIW-Maintain Datasources, am I right, that the delta does not collect those fields, or it is collected, just not sent to BW systems?
Any good idea, how can we get that fields in other way, because it seems, that the datasource cannot be modifyed, because of the other countries' BWs, connected to teh centra SAP.
I hope i were clear, but if not, please ask me.
Thanks for Your help.
Laszlo

Hi,
If a field is hidden in SBIW-Maintain Datasources, am I right, that the delta does not collect those fields, or it is collected, just not sent to BW systems?
--> As hidden fields are already available in extract strucute, unhiding will not create any problem. As far as i know hidden means it will transfer data from extract structure to further.
--> You can try pulling this particular data using generic datasource. OR
--> Enhance datasource by adding required fields and use. OR
--> Unhide files and use.
Note: Bit careful while transpporting datasource to production as time stamp changes.

Relation between LIS datasources and Extract Structures

Roberto,
Your detailed information does make it very clear why the SAP creates 2 SnnBIW1, SnnnBIW2 tables, and a structure.
I have another question related to this process.
Once you create a datasource from the custom LIS structures, you can assign a Development class to that datasource.
But the automatically created 2 tables and the structure are local objects, and you cannot reassign them to other object. That is fine because when you export/import the transport, all the other objects are also transported.
But when we enhance the extract structures, it creates a structure ZASnnnBIWS which also HAS TO BE a local object. This creates a problem of how do we transport these changes?
I would appreciate your insight into this.
Thanks
InduBala

I check from LBWE maintenance structure column, and the fields are there on the left hand side for the selection criteria.
How would I check "..fields you have enhaced are ready to use...." from LBWE.
From RSA6, I would doubleclick on the LIS datasource, and I see no enhanced fields and therefore could not see if they are hidden.
"Did you check in LBWE if your strcutures have the fields ready to use?" How would I do this? Maybe this is the problem.

Data extraction from sap r/3 to flatfile

hello Guru's
i am new to this feild. i got a requirement in such a way i have to extract data from feilds of different tables to flatfile.
( actual Scenario is we want to send data to sybase server through flatfile)
plz send me some documents how to proceed with the specification
usefull code in this regard is lot helpfull.
thanks and regards
aj

Hello Raja,
Here are some simple steps ...
When you want to load data from a flat file, there is no process of datasource replication. The datasource has to be created manually on the BW system itself. When creating this datasource you start from the InfoSource and assign the source system for flat file load. This is usually something like PC_FILE or FLATFILE.
Then you can start creating the datasource. You need to mention the field names in this datasource. Note that in your flat file, the sequence of fields must exactly match the sequence of fields in the datasource, else the data will be wrongly mapped.
On the same screen and tab you can also do a preview of the data that will be loaded. Click the preview button and put in the path of the file. Mention other details like header row, and number of rows to be displayed and then you will be able to judge if the data is being loaded correctly or not.
When loading the data, then file cannot be open else you will get an error message. Also to be able to schedule the flat file loads in process chains, the file cannot be on your PC. It has to be on the application server.
This is some basic info. Please post back if you need details on any aspect.
Hope this helps...
Assigning points is the way to thanks in sdn.
