Generic Datasource using Infosets

Dear Experts
What can be the problems we face when we do Generic Extraction based on Infosets in ECC or R/3 and what are the other alternatives to this one?
Thanks for your inputs,

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.

Problem in creating a generic datasource with infoset

Dear Expert,
I have to create a generic datasource with infoset. I linked the infoset with a test program below. In the program, I have one selection option, which is s_order. After creating an infoset and a datasource, this selection option 'SELECT_S_ORDER' is added to my extract structure. However, after try filtering with this SELECT_S_ORDER, it doesn't filter data at all. Why? I want to filter data with my s_order.
REPORT ZBI_DS_TEST.
tables: vbak.
* DATA

What do you mean by linking program with infoset?
Do you get the field in your RSA3 Tcode?

Generating a Generic DataSource using Function Modules

I am attempting to create a generic DataSource using a function module. All of our DataSources are business content or custom generated that involve views. At least in our company this is true. Is there any resources available to me with examples on how to do this. I have looked at SAP's 'simple example' and would need a ABAP/BW Guru to figure it out! Any help would be greatfull. Thanx. JJ

Hi Jerry,
The simple example should provide you with the necessary requisite. All what you need to do is to
create your own extract structure and assign that as type for the table parameter e_t_data.
Now you will get the selection criteria, as well as the fields selected in the datasource from the 2 incoming tables. You need to write the necessary abap code to execute a query and populate your extract struture.
Once important peculiarity of this function module is that it is called several times, or as many times as the MAX parameter + 1. ie, once for each row fetched. Hence you will find a persistence method of using a CURSOR with HOLD property to retain the data between the function calls.
The help in generic datasource explains the 3 modes,
initialize, first call and the repeat call for the
function module. The simple function module example actually provides the necessary logic to deal with these modes and the example uses the sflight table.
Hope that is some information that could help u begin with.

Generic DataSource using function module

Hello experts,
I created a generic dataSource using copy of function module RSAX_BIW_GET_DATA. It is syntactilly correct. But when I execute and debug associated generic DataSource in RSA3, this generic function module could not identify DataSource(i_isource) and update mode(i_updmode).
Could you please answer what went wrong?
I also created by using copy function module RSAX_BIW_GET_DATA_SIMPLE. I did not find above such problem. The generic DataSource is executed fine in this case.
Thanks in advance,
Zak.

Creating generic datasource using function module in R/3 4.6c

Hi,
I am not able to see the option (in TC RSO2) to create generic datasource using function module in R/3 4.6c. Is there any special plug in or some SAP Note to be applied to get the option ?
Waiting for a quick response.
Thanks and Regards,
Deepak

Hi Sat,
Thanks for the reply.
I know that creating generic datasource from function module is available in R/3 4.7.
In 4.6c version there are only two options available. They are Extraction from DB View and Extraction from SAP Query.
The third option i.e. Extraction from Function Module is not available in 4.6c. I wanted to know if there is any plugin that needs to be installed to get this option.
Thanks and Regards,

Problem while creating generic DataSource using table

Hello all,
I am creating a generic DataSource using table EKBE. It is giving error " invalid extract structure template EKBE ". The reason is " The system tried to generate an extract structure with the template structure EKBE. This operation failed, because the template structure quantity fields or currency fields, for example, field MENGE refer to a different table (EKPO)".
Could you suggest how to approach?
Thanks,
Zak.

hi zahir,
In your case the reference table used for quantity is ekko and the field is meins.
and the reference table used for currency is ekpo and the field is waers.
So you are not taking data from a single table. so you better create a view give the table name ekbe and select the corresponding fields you want.
Add MEINS and WAERS and as well your required field in the view for example Zview and for Quantity field mention Zview as reference table and reference field as MEINS same for WAERS.
try this if it doent work, tell me what error you are facing.
with regards!

Generic DataSource using FM - Delta doubt

Hi All,
I have few doubts on Generic DataSource Delta.
I am working on one HR requirement. where I need to pull the Mandatory courses information.
to get this done, we have created one Generic DataSource using Function Module.
FM has huge and complex logic, at present it is taking long time when I run in RSA3, if I continue with this to BI, daily running FULL load to BI is not suggestible, because it takes much time to load.
I have planned to set the Delta, just want to know what would be the best option to set the delta option for this requirement? and how? I have 2 dates (Course Start and End dates), Employee, Course Id, Course Type, Position, Job, etc in my DS structure.
Please suggest someone so that I can do FULL load once in BI and continue with Delta without missing any delta records going forward.
Regards,
Kiran

Hi,
In mystrucure used dates are not relating to aedat and erdat, they are CHAR type. here the requirement is little different.

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.

Error when extraction with generic datasource using function model

Hi,experts,When i check the error log in bw side for one egeneric datasource from R/3 side , it shows all the data from the datasource has been extracted ,and the error lies in the data selection .But when I use the Tcode RSA3 to check the datasource to check the functionality of selection ,its seems ok .
Could and I give me some clue ?

Hi,
Seems function module checks the selection in the infopackage while loading the data. Could you check if there is any selection which is expected but not given in the infopackge or incorrectly given.
Hope this helps.

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.

Identifying the target system using FM extraction in a Generic Datasource

Hi all,
We are using a Generic datasource using FM for extraction from R/3 system to BW system. This Function module picks data from a Z table! After each successful delta extraction from the table, a flag field is set to identify whether the data is pulled or not.
We are about to use BO data services which is connected to the R/3 system to fetch data. For capturing delta records after the BW run has happened, the table can be added a new flag field to pull delta for Data services.
Is there any way to identify which target system's extraction is running particularly in the function module (for e.g., if BW extraction is triggered or BODS extraction is triggered) so as to set the respective target flag in the Z table?
Regards,
vivek

Leandro,
The calling program of your FM should have a local variable I_RLOGSYS which is populated with the BW server ID.
If you don't know how to access a variable in a program that is in call stack using field symbols, search SDN.
I haven't tested this, so you may have to explore a little.
Good luck.

How do i assign master datasource to my generica datasource

Hi All,
I got confused when linking master datasource to Generic datasources.
I have created a generic datasource using View in CRM system (tables - CMSD_CB,CMSD_LO_QUANT AND CMSD_LO_PRICE) and replicated in bw.
all records are coming to BW system and it is working fine.
We want to link master datasources- 0ORGUNIT and 0BPARTNER because commission analyse is done based on Sales Representative(business partner number) wise quantity and price.
- 0ORGUNIT will give all CRM and R/3 sales offices, sales group...etc
- 0BPARTNER will give all business partner ..etc
Could some one help me how to proceed/.
Thanks in advance...
Mahantesh

Hi Mahantesh,
Since SAP is already giving you the datasources, why don't you join the data togther into a ODS table or create a InfoSet that shows the join for you. Cheers! Bill
