Generic datasource with function module

I am trying to create a transactional generic datasouce with fm.
I create my structure ZNVBAK1, create a function group ZRSAX, a FM ZRSAX_BIW_GET_DATA_SIMPLE1 and I adjust my source code.
I activated both FM and Function Group.
Now under RSO2 I enter the datasource name as in my code, I enter the application component SD as well as the description
When I choose extraction by FM, nothing happens, no windows prompting me to enter my function module as well as extract structure, I checked everthing look good.
Any Idea what I might be doing wrong?
Thanks!!

Hi ,
First put values in Short Description, Medium Description & long Description,fields and then click on the Extraction by FM. You will get those filelds unabled.
You can also refer.

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

How to copy a generic extractor with function module into a new system?

Dear Gurus,
i would like to know how i can copy a gneric datasource with function module from one system to the target system.
Thank you
Cheers

Hi Anesh,
thank you for replying.
Since the Datasource will have a new new in the new system, i will create a new one.
Create a generic datasource base on the table is not the problem.
My problem is how could i copy the FM in the new system?
If you can help me on that, it will be fine.
Thanks

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.

Generic Datasource with Fuction Module with delta on Created Date

Hi Experts,
I have created a generic datasource using Function Module RSAX_BIW_GET_DATA. I have copied this function module and created a my own Function Module. I want to load delta using this. But I don't know how to handle delta in the code.
my code is working for full load but not for delta. I have seen that in ROOSOURCE tabel the Delta field is showing the AIE instead of D and extraction method is showing as F2. I have searched a lot of forums and articles but didn't get how to handle this.
Please advice.

Hi Amit,
Go through the link as suggested by AKhan which lets you understand the concept of offsets and the last extraction status.
In case of Table or View based GDS, the system takes care of the deltas based on the selections you make in the "Generic Delta" screen whereas in case of FM based DS, it is your responsibility to handle this part. Within your code, capture if the load is a Delta load (I_UPDMODE = D). Since your delta is on Created Date, maintain a Z table with name of the DS as the Key and a field representing the current value of the Delta field(created date in this case). When you first load the delta, there will be no record for your DS in this table. Create an entry with the current day. Next time when you load a delta, take this value, compare it with sy-datum and get all the records falling within these days. This has to be done in the Select stmt. Once selection happens, replace the value in the Z table with sy-datum. This way you can simulate the delta. The Z table can be used for other FM based Datasources also as it has DS as the key.
It would be easy if the exact SAP table where RSA7 delta field status is stored is known. Otherwise, the above method can be used.
Revert for any further queries.

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,

Generic delta with function module

Hi Gurus,
Is it possible to create a generic DataSource with delta support using function module following the queue delta mechanism (u can get some function moduel in MCEX function group, and check the outbound delta queue before and after update in transaction smq1.
I can store the delta data using qRFC and collective update mechanism. but I don't know how to create a generic data with delta and how to attach a rfc destination (& logical system) to the data source. The Source system information is stored in the table "ROOSGEN". Is there any configuration setting required to do the same.
Regards,
Jugal

Jugal,
What I understand you to be asking is if it is possible to create a generic delta extractor which uses the delta queue. If this indeed is your question the answer is yes.
First you need to create your data source so it is visible via tx RSA5 and need to make sure that the delta type (ie ABR, AIM)is set appropriately for the datasource.
The issue however is determining from where you will associate your delta hook (when will you write to the queue)? I have in the past utilized BTE's, Business Transaction Events to write information out to the delta queue, you can see a list of available BTE's in your system via tx FINF.
Once you find a place to write your deltas from you call the below FM with the appropriate datasource.
RSC1_TRFC_QUEUE_WRITE.
Once you have done this the standard BW extractor for deltas will pull the information from the delta queue. But from what I understand you just want to know how to associate the data with the delta and that is the FM listed above.
Hope this helps,
Cheers,
Scott

Generic Datasource by Function Module.

Hi there,
Our ABAP guy is building a function module to bring data to BW by using Generic DataSource. My qtn is how we are going to handle delta?
Can we use the delta provided in Rso2 or we have to hard code it in the function module?
Your prompt help will be highly appreciated.
Kara.

Error in Extraction with Generic Datasource via Function Module

Dear Gurus,
Iam working for BI-HR module.We are extracting data with generic data source via function module. The client some more extra fields in already existing DS. So we made a copy of that Function module and tried to create new generic DS, we got error while extraction like "Error occured during the extraction process". Can you please help in resolving this issue, your valuable suggestion would be highly appreciated.
Thanks and regards
Arun S

Hi,
Which structure are you using??
Are you using the same old structure for this function module as well.
Have you enhanced the structure with new required fields.
New extrac fields needs to be added to existing structure if you are using the same or create a new one and make sure that you have all the fields in the structure which you are going to use in the data source.
You need to take care for the append as well and the issue could be in the code as well.
Make sure you have written the proper code and just for the new fields done an append
Thanks

We have a requirement to create a Generic Data Source which will be having fields from the tables COEP, COBK & BKPF. Generic datasource should be delta enabled. We are planning to achive it by writing a Functional Module.
No my question is can i use BWFI_AEDAT & BWOM2_TIMEST tables to make Generic Datasource delta enabled. If i can then please let me know how. If i can't then please let me know what should i do to make it delta enabled.

Generic datasource by function module to fetch data from multiple tables?

I'm writing a function module to fetch price, for generic datasource.
At first, extract test is OK. But InfoPackage never stop when loading data to PSA in BW.
And I find the example codes:
     OPEN CURSOR WITH HOLD S_CURSOR FOR
      SELECT (S_S_IF-T_FIELDS) FROM SFLIGHT
                               WHERE CARRID IN L_R_CARRID AND
                                     CONNID IN L_R_CONNID.
    ENDIF.                             "First data package ?
* Fetch records into interface table.
*   named E_T_'Name of extract structure'.
    FETCH NEXT CURSOR S_CURSOR
               APPENDING CORRESPONDING FIELDS
               OF TABLE E_T_DATA
               PACKAGE SIZE S_S_IF-MAXSIZE.
    IF SY-SUBRC <> 0.
      CLOSE CURSOR S_CURSOR.
      RAISE NO_MORE_DATA.
    ENDIF.
    S_COUNTER_DATAPAKID = S_COUNTER_DATAPAKID + 1.
ENDIF.
There using Cursor to fetch data package by package, and raise exception NO_MORE_DATA to stop the loading process.
Now I fetch data from multiple tables, I don't think I can use Cursor.
Then How can I handle this?
Thanks a lot.

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 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
