Generic Extraction using Infoset Query

Hi Experts,
I am trying to create on Infoset query on the R3 side for creating one generic Extractor Joining EKKO and EKPO table.
u2022I have created the User group in SQ03.
u2022I have created the Infoset in SQ02 and selected few 5/6 fields from each EKKO and EKPO tables into the Field Groups of the Infoset.
u2022I have generated the Infoset and assigned it to the user group created on SQ03
u2022I have created a query on SQ01 using this Infoset and deselected the u201Ctextu201D fields created by default and selected the Basic list. Done everything needs to be done in there.
Now when I am going to RSO2 and created the extractor using that Infoset, I am not seeing the Function groups that I have created in the Infoset in the Extract Structure, rather its pulling all the fields that is there in the Infoset joining both tables. It should show me those 5/6 fields that is there in the field group.
I just want to see only those 5/6 fields in the extract structure of the DS.
I am not sure what is missing.
Any documentation on the same or if anyone faced similar problem, please help.

Hi,
You can create the infosets in r/3 using the t code Sq01,sq03 etc.
You can create a generic extractor in r/3 using the tcode rso2 and that you can specify the infoset name.

Extraction using infoset query.

Hi,
I have an extractor in R/3 which is using infoset for extraction. The infoset contains some logic for extraction. I want to debugg the infoset. As the infoset is not attached to a query how can i debugg the code written in infoset.
Thanks & Regards,
Soumya.

Soumya,
If the problem is in the data which is being extracted from R/3 then debug the datasource by:
use transaction RSA3 in R/3 to execute the datasource and put a tick in the option "Debug Mode".

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 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.

Generic Extraction using Function Module

i want to know the step by step procedure for this extraction and also why we need to go for this, i mean in which scenario this is the best method. and do we need to write any abap code for doing this.and also i need what alla transaction codes we use including concepts.

1> I don't have a step by step procedre doc. But, there is a sample fucntion module, RSAX_BIW_GET_DATA_SIMPLE. You can take a look at this to create urs.
2> It is an alternative to the of using InfoSet query (using ABAP datasource) where you cannot split the data to be extracted into DataPackages. So, it is very helpful for huge extracts.
3> Yes, you have to write ABAP code for this.
4> Transactions used.

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.

Generic DataSource using InfoSet on BI 7.0

Hi gurus,
I need to extract data from a InfoCube through a generic DataSource. I have created an InfoSet Query based on this InfoCube and I have noticed this kind of InfoSet is not the same that is used by Tcode RSO2.
Does anybody know if there is any way to get this vai generic DataSource?
I need to get data from Infocube because de Delta Control must be the package number.
Thanks in advance,
Silvio Messias.
P.S.: The version of my environment is 7.0.

Hi Ashok,
Into the Tcode RSO2 (Generic DataSource) I have the option to collect data from an InfoSet. This InfoSet must be created through Tcode SQ02, right?
I woult like to get data from a Infoset Query based on InfoCube, created through RSA1 on BI 7.0.
Is there any way to do it?
Thanks for your help,
Silvio Messias.

Extraction using ABAP Query

Hi Experts,
I have a data source in which the extraction is using ABAP Query. From RSA2 I got the infoset name. I would like to know if the extraction logic is put inside this infoset. If so how to see the extractor ouput in R/3 and how to debugg the infoset. I can't put break point in infoset. I tried to debugg the extractor through rsa3 and it is not going to the infoset also.
Please help me as I don't have any experience in BI.
Thanks,
Soumya.

Hi Soumya,
Infosets are similar to views created on different tables by linking them with one another. So instead of debugging one should look for how this tables have been linked in tcode SQ01.
Hope that helps.

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

Using Infoset query

Dear Experts and friends,
I have created a infoset using the logical database sdf, and have created a query adding two more tables( mara and marm) giving conditions.
The problem is when i try to add some fields under basic list for list output the message comes " You placed fields from different parallel branches of the hierarchical data source in the same line. . This makes no sense. The list will not be displayed as you desire. . List is only displayed in simple format for correction purposes. . Please check the sequence. Button allows you to color list fields according to the hierarchy".
I have tried all the possibilities of list order and still the message comes.
eg.
when i tick the profit center(faglfreesel-prctr) first and then material number(bseg-matnr) , this error message comes.
Please tell a solution for this as this report wants to be moved to the production server this week end..
Thanks
Sujeel

Soumya,
If the problem is in the data which is being extracted from R/3 then debug the datasource by:
use transaction RSA3 in R/3 to execute the datasource and put a tick in the option "Debug Mode".
