Function module in Genaric Extraction

hi,
this sudhakar
can any one helpme out about this
when do we go for functional module
and what senario we can use
can any one hlepme about this
I didn't work on this
thanking you
sudhakar

Hi sudha,
under Generic Extraction... normally... when we dont have a bussiness content then only we go for generic extraction..
in that , we select Function module for a specific conditions... that means. when we want to extract data from multiple tbales...(more than one table..) and those tables having ONE- TO MANY relationship. then we select this functionmodule extractions..
if the relationship between tables is ONE -TO - ONE, then we go for extract from Views
i think this will helpfull to u.. plz dont forget to ASSIGN POINTS.
thanks

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.

If there are more number of tables and data in those tables can be represented using joins then we can use this type of extraction

How to debug mapping function module during delta extraction?

Hi experts,
Somehow our delta is not working properly, and i would like to debug our mapping function module. How can i debug it during a delta extraction?
Some info:
Our source system is CRM and our extractor is extracting one order document (contracts in this case). I know that when we modify a contract, a bdoc is generated and then passed throught the mapping function then the extracted data to the delta queue. I just need to debug when the bdoc is being mapped to see what's wrong with the extracted data.
Thanks in advance,
Van

Hi,
Since you are using a Function Module for the Extraction. Edit the Function Module and give "BREAK-POINT" before the loop command. Check and activate the Function Module.
Now Extract the datasource using RSA3. Now you can debug it. After checking remove the "BREAK-POINT" from the function module. Also Check and activate the same.

Error while calling the Mapping function module for BW Extraction

iam getting runtime error while calling the BW mapping function
The error description is as shown below.

Help on Function module in Generic Extraction

Hi ,
i am writing FM in for Generic Extraction.
i am dont know ABAP.
i am using RSAX_BW_GET_DATA_SIMPLE..
i created Strcture from the MVER table ..
Strcture fileds : MATNR
                       GJAHR
                       GSV01,
                       GSV02,
                       SUM.
SUM is not in the MVER table .
Pl . give me code for this logic ..
Logic :
Take sum of GSV01 , GSV02 from table MVER with the key
                   MVER-MATNR = MARA- MATNR and
                   MVER-GJAHR = Year from SY-DATUM.
Pl . give me code for this logic..
i assign points ..

Hi Diego Lombardini ,
thanks for fast reply..
i retrieve fields from 6 tables , thats why i choose function module but
my main logic mention above .
i created view but it gives wrong values bcoz lot of joins .
so i decide FM is better option ..
Pl . provide code for this logic ..

Function module searched: Data extraction from BW to R/3?

Hello everybody,
has anyboday any idea on which function module or function group could be used for data extraction from BW to R/3?I have seen some threads,and found the function group RSAX which is actually for extraction from R/3 to BW,is it also suitable for the other direction(BW to R/3)?
I have looked for this topic for a long time,but so far no success...
Would you like to give me some hints?
Regards,
Liying
Message was edited by: Liying Wang

Hi,
It's going to be an extraction to specific application in R/3 - couldn't be any universal extractor - applications have their own specific.
But you can try application specific retractors, as examples look here:

How to control iteration of function module in generic extraction to BW

Hi Experts,
I am customizing standard Function module RSAX_BIW_GET_DATA_SIMPLE. My problem is, while excecuting datasource in RSA3, my function module is repeating many times.....example if my FM fetches data of 70 records.......FM is repeating 70* n times while executing it in a data source.
How to contol this loop?
Can anyone please help me.

Hi,
This FM is used to get list of files from Application server (will work in Background). This cannot be used to list files from presentation server. There is no way , by which you can process presentation server files in background mode.

How to do data source ehancement by using "Extraction by function module"

I have one customized datasource "ZSOURCE" in R/3, this datasource use Extraction by function module, namely one functiona
module "ZBI_FM_EX"and Extract. struct "ZBI_EX".
Now I want to add one field "ZNEW" from standard SAP table LIKP into extractor "ZBI_EX" and write coding in ZXRSAU01.
Question, could I add new field "ZNEW" into Structure:"ZBI_EX"? Do I need to change anything in functional module "ZBI_FM_EX" itself?
Many Thanks!
rajatina.

Hi Dear,
It is good to write the code in your function module i.e. ZBI_FM_EX. becuase writing the code in ZXRSAU01 include program will affect the loading performance. instead of looping the data two time (one in your FM and again in ZXRSAU01 ), you can get the same will only loop.
Thanks

Generic delta extraction using function module

Hi.
I have a generic datasource , extraction being performed by a function module. The extraction works fine in full update mode. The extract structure has a timestamp field.
I have enabled generic delta using this field(i.e., marked this field in RSO2). I understand that with this setting, I should be able to get delta data when I do a delta request. But it does not seem to happen.
I checked the ROOSPRMSC table for the last(local) timestamp stored there. Now when I do the delta upload I expect to see only those records which are younger than the stored timestamp of last upload.
But I still get the entire set of records.
Questions are :
1. Do I need to explicitly code for fetching the delta in the extractor ?
2. If not, what could be the reason why generic delta is not working ?
Thanks and regards,
Anuradha

Hi GFV,
I read-up all the forum entries on this topic but could not find anything specifically dealing with my problem. I have browsed through the how-to paper on generic delta as well.
I am quite sure that we don't need any special coding in the extrator for generating delta generically. Even the how-to paper does not mention that.
I have used the FM RSAX_BIW_GET_DATA_SIMPLE as a template
for my extractor(as suggested by F1 help in RSO2). This FM does not even have the i_updmode flag in its interface.
Thus this function module always does full extraction and I expect the system to take care of delta using the timestamp field.
Are these assumptions incorrect ?
Regards,
Anuradha

Error while creating Generic Extractor via Function Module

Hello Guys
I have created a Generic Extractor through a Function Module. I took the Standard FM: RSAX_BIW_GET_DATA_SIMPLE, gave it a new name and activated it. I made a few changes in it, like giving my structure name for E_T_DATA and giving the list of tables, from where I need to get the data. Then I created the datasource in RSO2 by giving this function module and the extract structure.
The DS was created properly, but when I check in RSA3 for records, its giving me an error: ---> The extraction program does not support object YCNA_INVY_TRNS
What do i do now? Can someone please tell me, what changes I need to make in the standard FM to suit my requirements??
Thanks.

Hi,
Just try to reactivate the structure once again. And when you open the function module, if the problem still persists just try to press Return key several times. The message you are getting is just a warning message.
PS: I am not sure whether this is the correct way, but i personally resolved this by pressing the ENTER key 4 or 5 times. So just give a try.
