When to go for generic extraction using view and infoset query?

Hi,
Can anyone clarify me when we should go for generic extraction using view and when we should go for generic extraction using infoset query....
Also what is the difference between view and infoset?
I tried but could not find out....
Regards,
Kalyani.

Hi Kalyani,
We normally go for View or infoset when the data to be fetched in BW is distributed in different tables in SAP R/3.
Had the data been available in one table we can easily build our datasource on that table but if there are more tables then its not possible to do it without Views or Infosets. You can use Function Modules to build your datasource in case it involves complex logic to figure out the data from various tables.
Depending upon the table relationships we create view and include various fields from these tables in that view. Same is with the Infosets, you can have more flexible options like Outer Join, left outer Join etc.

Generic Extractors for HR Reports using views and Infoset Query

Hi Friends... I am working to come out with the HR reports in BW for the HR reports which are already there in R/3. The HR reports in R/3 are created based on Infoset Query.I could not find any standard business content cubes which can give me these reports.
1)So please can anyone give me step by step approach so to create a generic extractors based on Infoset Query.
2)And also how to populate the data into the fields of the generic extractor which is created by Infoset Query( Please provide any sample ABAP code if available)
3)can anyone give me step by step approach so to create a generic extractors based on View/Table.
4)And also how to populate the data into the fields of the generic extractor which is created by View/Table( Please provide any sample ABAP code if available)

Generic Extraction - query view and infoset query difference

Hi Guys,
I want to know the Generic datasource difference between Extraction from view and Extraction from Query .I have read some threads and documents, still i am not getting the exact difference.
My understanding :
Views: combination of tables to view the end result , we use views.
Infoset query also with help of SQ01, 02, 03 : we combine tables to see the result.
both use primary key to select the data.
Please help me.
Thanks ,
Nithi.

Hi Nithi ,
When we build the datasource on the View
View is basically a table in which you can take data from many table combniation .
in view you can specify the table join condtion and selection condtion
View data gets updated as the data in the source table gets updated
When we build the datasource on the Infoset
Data source str gets filled from the infoset query .you need to use SQ01 and Sq02 transaction for this
in infoset you can define the tables from which you want to read the date .There is also facilty to write ABAP code which will process the data and fill the the data source str using infoset query
infoset query read the data from infoset and transfer to data structure
Thanks

Need code for Generic Extraction using FM using multiple tables.

Hi Experts,
We are doing a generic functional module extraction based on four tables - say,
Table TT1 u2013 with fields AA, BB.
Table TT2 u2013 with fields CC, DD.
Table TT3 u2013 with fields EE, FF.
Table TT4 u2013 with fields GG, HH.
The value of the field BB = DD.
The value of the field DD = FF.
The value of the field FF = HH.
The key field with which we have to extract data is AA.
We have created a structure for the above tables u2013 say STR containing all the fields from the above tables.
Now as such all the data from the tables is in the internal table ITF.
This data from the internal table is passed to the structure STR.
Somewhere, I think we are making a mistake. I do not know where.
When we check the datasource extraction in RSA3, we find that there is data only from the Table TT1. Data from other tables does not populate in the datasource.
We do not know where we went wrong.
Kindly help us.
Thanking you all in advance.
With Kind Regards,
Shreeem.

Hi,
You will have to use the select query with joins as given in the below example,
SELECT pcarrid pconnid ffldate bbookid
INTO CORRESPONDING FIELDS OF TABLE itab
FROM ( ( spfli AS p
            INNER JOIN sflight AS f ON pcarrid = fcarrid AND
                                       pconnid = fconnid    )
            INNER JOIN sbook   AS b ON bcarrid = fcarrid AND
                                       bconnid = fconnid AND
                                       bfldate = ffldate     )
WHERE p~cityfrom = 'FRANKFURT' AND
        p~cityto   = 'NEW YORK' AND
        fseatsmax > fseatsocc.
But I would suggest you to better create a Data base View with all the required tables and then use that view for data selection in your FM.

Delta for generic extraction using FM

Hi All,
I am trying to create generic datasource using function module. I need to set delta functionality for this DS but I don't know how to set delta for FM.
Do I need to give delta specific field in RSO2? My delta specific field is either AEDAT or ERDAT? Is it possible? how to write code for this?
I have around 13 tables & there is no stadard DS for these table so is it correct way to use generic using FM or is there any other way?
plz suggest & if u have any step by step document for FM plz provide.

Hi Manesh,
Yes you need to set up your delta enabled field in RSO2 when you click the delta button for the datasource.
Usually for generic datasources we use any date field to genarete deltas and looks like you have the same (AEDAT and ERDAT a re date fields).
You dont need to write any code for this. Just provide any field for executing delta and initialize. It will get you the delta based on the date.
In some scenarios, we get postings happening on an older date and hence dates cannot be used, in those scenarios we can go by numeric pointer.
Creating a datasource on 13 tables, i ma not sure how efficient it would be (mainly depends on the data volume on these tables) but yah writing a function module will be fine.
Let me know in case of any clarification
Thanks
Sachin

Scenarios for Generic extraction

Hello experts ,
Please give me some scenarios where we will go for the extraction using
function module,
infoset query,
View.
Thanks in advance,
pragya.

Hi Pragya,
Generic extractors are of 3 types:
1. Based on table/view
2. Based on Infoset Query
3. Based on Function module
In some cases Business Content will not give your required data sources , In such scenarios you need to develop your own data sources ( Views / Function modules ) , Then you can bring that data source to BW and use that .
if you can't find the suitable business content data source then you have to create
your own data source ( Generic )
or enhance the given data source.
Need for customized generic extractor
Business Content may not have a suitable
Data Source for your application.
Business Content may require additional enhancements that need data that is not supplied by SAP BW.
The application may not have its own generic data extraction method.
We have used our own custom programs to populate tables in SAP system.

When we go for Views and Function Modules for Generic Extraction

Hi Experts,
Can you please explain when we go for extracting the data using Views and when we got using Function Modules using Generic Extraction from R/3 system to BW with examples. And also can you explain when we go for delta for the above both scenarios.
Thanks for you help in advance
Rohith

Hi,
Scenario for Extarction using FM
Imagine the scenario where you need to extract data from
tables having no common field between them and thereby preventing you from creating a view on top of those tables..
Or simply consider tables that are highly unrelatd in terms of fields, but you have a requiremnt to extract data from them.
Also Refer.

Generic extraction using table

Hello friends,
We have three methods in Generic extraction, as we know.
1. Using view/Table
2. Using FM
3. Using Infoset Query
I know pretty well the extraction using View, but when do we use "Table"?
Is there a specific method to perform generic extraction using TABLE?
Please clarify

Thanks for the replies.
In case of a generic extraction with view, i've followed the below procedure.
1. RSO2.
2.create a generic datasource by giving a view name and selecting the fields for selection criteria, save and generate.
3. replicate data sources in BW.
4. create an infosource and assign the data source, mapping and create an infopackage to load data.
Now ,
1. how do we enable Delta for this method?
2. Is this possible at all? if yes, how?
3. How do we proceed after the replication of DataSources in BI? specifically, procedure in BI?
Pls clarify.

Bussiness Scenario for GENERIC EXTRACTION

Hi friends,
 can any one explain me... in what situation we go for Generic Extractions..
The normal reason is When the Bussiness Content Datasource is not matching with our requirement.. we go for Generic extraction..
 I told like this only... but they are not satisfied with my answer.. and they asked .. tell me the bussiness scenario( in what situation u done generic extraction)
so, friends... could any one plz explain me any scenario... which you done for generic extraction...
 i will appriciate by giving points to the appropriate answers..
Thanks

Hi,
These 2 below links may be helpful,
GENERIC DATA EXTRACTION USING FUNCTION MODULE
Difference between Generic Extraction and Enhancement of existing Extractor
1)Go to RSA6 and find the data source you need to enhance.--> Display
2)Double click on the Extract structure.
3)Now click on the append structure button to add the required field on to the existing structure.
4) add your required fields with ZZ appended to your field.
5) Save & Activate the append structure. Then go back and make sure you activate the extract structure also.
6) Now again go back to RSA6 and select your Data Source. But this time go to change Data Source to remove the hide option to the enhanced fields. By default theyll be in hide mode. If you dont remove the hide field then this field will not be seen in BW side.
7) Now go to SE38 to write the logic to populate the data into the enhanced field. Program name to write the logic is ZXRSAU01.
8) Check + Save + Activate.
9) Check in RSA3 if data is populated as per your requirement.
10) Replicate your Data Source.
11) Now go to Data Source/ Trans. Structure screen. Now you can see the enhanced field on the right hand side.Enhancements:
Enhancements:BW Side:
Go to CMOD.
1. To Save give Description  createcreate new projectgive the project name
2. Select the radio button Enhancement Assignment and give the Enhancement name you want and press Enter.
3. If the Enhancement is already assigned to some other project it will display the same message saying it is already assigned it some other project. Click on
4. If the Enhancement is not assigned to any project save.
5. Give RSR00001 (For Variable Exits)
6. Activate the Project.
7. and click on the components button.Now go to Display
8. Now Double click on EXIT_SAPLRRS0_001. In that you can see an include ZXRSRU01.
9. Double click on that include, it will say program name ZX are reserved for includes of exit Functions groups.
10. Just Press Enter.
11. Itll Pop-Up a window Create Object.saying Include ZX. Does not exits
12. That is where you have to write the code for the variable exits. BW: Virtual
13. RSR00002 Chars and Key Figures. BW: Moving Characteristics.
14. RSR00003

Delta for Generic Extraction

Hi all,
Can anyone tell about delta for generic extraction i.e 3 options in detail and when do we use it.
thanks in advance,
chandra sekhar

When you want to customize existing datasources at R/3 sides then you can do that with customer exits.
Suppose if you want to add a column to the existing datasource then you will use append structures (Transaction SBIW-> Edit Data sources - Enhance Datasource) then to fill the column you will write the code in these Exits.
There are 4 types of Exits available.Function Group (XRSA)
EXIT_SAPLRSAP_001 Customer Function Call for Supplying Transaction Data
EXIT_SAPLRSAP_002 Customer Function Call for Supplying Master Data (Attributes)
EXIT_SAPLRSAP_003 Customer Function Call for Supplying Text
EXIT_SAPLRSAP_004 Customer Function Call for Supplying Hierarchies
As you are aware there 4 types since the datasources in R/3 are predefined to fill the data of BW viz, attributes,Text,Hierarchy and Transaction.
Check the below forum discussion for more information..

Issue with generic extraction using FM

Hi All,
I am trying to load from one DSO to other DSO, where i am trying to use generic extraction using FM, where i created strucutre of second DSO .
created Generic datasource with Function module.
when i am loading data using infopackage, its loading perfectly into PSA(with 100 records) and when i am loading thru DTP to Data target( second DSO), it is looping many records in each datapackage(like 8 million in each package) and updating into datatarget finally 100 records. but it is taking long time to finish the process.( i copied RSAX_GET_SIMPLE_DATA) and added transformation logic to it .
so i would like to know, if there is anything i have to change in the Function module code, to fix this.
i would also like to know, request is already in PSA, will it again extract from FM, when updating thru DTP.
Thanks
R,man
Points will be awarded.

Hi
I also had the same process. In the code of the function module. just check the Raise Exception code, probably ABAP guy can help. Also try to debug the code in RSA3 in debug mode. Actually it is going to a infinite loop, I guess.

Code For Delta Extraction Using Function Module

Dear Experts,
I want a sample code for Delta Extraction using Function Module ( If it is customized already working code very helpful ), I have already created Function Module but Full update is happening. If I give delta update again it is retrieving all records. It is very urgent, if you have please send me to the following mail ID.
[email protected]
Best Regards,
SGK.

Dear KJ,
Thank for your response. I saw the code that you sent, you have used some ztables like ZSC_DELTA_IP, ZSC_SAFETY_DELTA, ZSC_SET_EXT_TIME
What are the fields that you have created in these tables , what is use of these tables, can you send the fields that you have used in these tables.
Thanks & Regards,
