Creating a Generic Datasource using Function Module

Hi Guru's
We are tryin to create a Generic datasource using function module, we have found few old how to guides for doing the same but it is not effective and need to be altered. Can anyone suggest me the latest step by step procedure to create the above, also if you have the how to guide kindly paste the link as it will be a great help at this point.
Thanks in advance

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,
Deepak

How to create a generic datasource from function module?

Dear experts,
I have created a generic datasource from function module. For this extrator, I created a function module and a structure.
I have now some difficulties to continue:
In this function module, i get data from different transparent tables. Then i put these data into an internal table.
I just don't know what is the relatioin between the structure i defined and this internal table.
I should make "iTab structure AA" in the source code?
Thanks

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.

Generic DataSource on Function Module - Query

Hi All,
We have a requirement wherin we have to pull data from MARM (Material UOM fields) table. This table has some 1,130,000 records. Since this table doesn't have a Last Changed on or Created on field we are not able to create a Generic Delta on the table itself.
We have come to know that in MM02, we can change the Unit of Measure fields for material. When we update in MM02, both MARA and MARM table gets changed. MARA will be updated with the last changed date.
So we are thinking of creating a Generic DataSource on Function module so that we can perform the delta on Last changed or Created on field of MARA.
I have a doubt about creating the function module. How should we achieve the initial load (Getting all the material and it's UOM to BW) and then Delta loads through the function module?
Does the first load needs to be or should be a full load?
If someone can tell me the steps that should be followed, it would be very helpful
Please let me know your suggesstion.
Regards,
Vivek Das Gupta

Hi
Could u try creating a view based Datasource.
Also u can do a full load in parallel by creating 4-5 Infopackages. After which a Init without data transfer can be done.
Hope this helps.

Error occurred while loading Generic extraction using Function module

Hi all
I'm trying to do INIT for Generic Extractor using Function module, but i'm getting error as "Error occurred in the source system"
Error message from the source system
Diagnosis
An error occurred in the source system.
System Response
Caller 09 contains an error message.
Further analysis:
The error occurred in Extractor .
Refer to the error message.

How you remove the error depends on the error message.
Note
If the source system is a Client Workstation, then it is possible that the file that you wanted to load was being edited at the time of the data request. Make sure that the file is in the specified directory, that it is not being processed at the moment, and restart the request.

Generic DataSOurce on Function Module

Hi Everyone,
I know how to create a Generic Datasource based on a view. I amfirst time trying to create a Generic DS based on FM. I know the steps. Like we go to SE11..select database type..give the name..select structure..give the name..enter the fields name in component save it..then go to SE80..select function gp..etc...etc.
My question is This function module should get data from two tables. In which step we need to mention the table names?
Can anyone please explain?
Regards

Hi,
If you would like to have a DS which'll extract using FM then you've to copy RSAX_BIW_GET_DATA_SIMPLE FM.
Now once you copy it then in that only you see the line:
open cursor with hold s_cursor for
select distinct pernr from pa0000
where pernr in l_r_pernr
and stat2 = '3'.
If you want to have more than one table then create cursors and use them accordingly.
Best Regards,
Rachit

I have created a a generic data source using function module to load data from PA0000 and PA0001 Tables ,Function module is working fine when i execute it indipendently and the data source is also working fine when i extract data using RSA3. it is showing correct no of records 157.
When loading data into DSO from BW (using 3.x/7.0 flows) data is comming to PSA all 157 records but in the RSMO the load status is showing yellow when i look into the step by step analysis it is

after and hour time load getting failed and in the error message it is showing " job terminated in source system---> Request set to red"
