Function Module extractor extracting as a Single Package?

Hi All,
I have created a generic function module extractor, which works fine, but extracts all the records in a single package. The default is set in SBIW as 50000 records. But right now I have only 2500 records. But I changed the packet size to 100 in my info package setting and also specified as 100 with in the function module.
But still I get all the data come as a single package of 2500. I want to make sure that this extractor will not create any problem in production, so I want to test the data packet size. Any suggestion. I have used he standard function module DATASIMPLE and I do setup I_MAXSIZE as 100 in the IMPORT parameter in the function and hav ethe following code in the function module...
         APPEND mgremp_stru to E_T_DATA.
          mseq = mseq + 1.
          if mseq = 100.
             G_COUNTER_DATAPAKID = G_COUNTER_DATAPAKID + 1.
             mseq = 0.
          endif.
    endloop.
    IF SY-SUBRC <> 0.
       RAISE NO_MORE_DATA.
    ENDIF.
    S_COUNTER_DATAPAKID = S_COUNTER_DATAPAKID + 1.
Any Suggestions?
Thx,
Alex.

Ramesh,
The simple truth is that what ever you define as a data structure for E_T_DATA should be exactly matching to your selections in the CUSOR. My scenario is way too trichy not just because too many sqls, but because of the nature of HR Tables. Same field will have two different values such as in one record SOBID refers to Org Unit, in the next record the same is Person and in the next record it is Position. So I should have the same field 3 times in a single record. But it is not possible. SO what I did was found 3 different fields whose length and type are same as what I need and selected them but inside my function module I manipulated with internal tables. So the extractor thinks I declare cursor for the same fields I defined in the data source (the value you use in E_T_DATA) and extract them in the FETCH. In the fetch all it checks internally is that whether the only the CURSOR selected fields are extracted , because you will update the E_T_DATA. I know this is little more than what I explained here, but this is the concept.
I am planning to have a weblog or a white paper published on this in a week or two.
If this idea helps assign points.
Goodluck,
Alex.

Function Module not extracting records when InfoPackaged is executed

Hi,
I'm using a Function module for extracting data. The DataSource is working fine in RSA3 with a selection criteria. But when i schedule the infopackage with the same selections in the data selection tab, Its not getting me any records into BW. In the Details Tab i get the message "Error occurred in the data selection" . I guess there is a problem with the data selection. Pasted below is the code i'm using for extraction. Can anyone please let me know if there is any issue with the code.
Also how do we pass on the value of I_MAXSIZE into the function module, the remaining parameters get the values from BW. And can anyone please explain me the concept of the "s_counter_datapakid" and when it should be incremented and where it should be located in the code?
Thanks,
AM

Function Module in a Generic Function Module Extractor

I want to use a generic function module (ZFM_CONNECTION_DETAIL) in a Generic Function Module based Extractor.
After Creating, I have checked it in RSA3... Data is showing properly on the Extractor Check.
And replicated on BW side, after triggering the extractor using infopackageu2026 only one record is coming on the target side (BW).
And one job is running endless on the source system.
Generic extractor on the normal code is working properly on both sides.
But problem occurs while I was using Function Module in the Generic function Module extractor.

How to Function module extractor

Can anybody give me a step by step procedure to do a function module extractor ?
Like the steps that I need to perform even before i start writing my code
Thanks
Shruti

Dear Shruthi,
Do a Search in SDN .you get lot of threads for FM Extraction ...
The easiest way to work out with Function Module is to copy the standard one and modify according to your reqirement.
The standard one is RSAX_BIW_GET_DATA_SIMPLE .
Dont forget to copy the Function grp RSAX into a custom defined Grp and Modify the Ranges options as per ur req.
and in Function module, in Sourcecode and Tables, Do modify the E_T_data with ur Generic datasource ,make sure u also modify the select statements within the sourcecode. If you have an idea on ABAP its really easy to work out.
And regarding the creation of Datasource.
Its really Simple.
Goto RSo2.
Give the name of Datasource.
Give the Fm name and Extract Struc ( name of D.S only).
Save and Generate.
thats it.
Dont forget to assign points.Its a way of saying thanks.
Thanks,
Krishna

DB table for function module extractor

I would really appreciate any comment or suggestion about this topic: Function module based extraction. I opened this thread on the BC & Extractors forum, but unfortunately none has given me any feedback yet.
Thanks & Regards, Davide

So none see any advantage with storing the extracted data in a materialized DB table, before transmitting the records to BW. Can I infer it's probably not a good idea wasting time with an additional massive write operation?
Cheers, Davide

Creating BW Function module to extract R3 Function module data.

Could you tell me how to create a BW Function Module to Extract data from R/3 Function module?.
Also, the BW function module needs to pass a date/time filter to R/3 function module basis which the R/3 function module passes the date/time restricted data to BW function module.
Thanks,
Gautam

You will have to create a function module in R/3 and then call the same in BW using the RFC call function option.
Please do not raise separate threads for each question - you have asked the same question in another post of yours..

Function Module Extractor with Internal Table

Hi All,
I have a need to extract records from a complex SQL Statements, so I will be using different SQL Statements and merging the results in to a single internal table. In the function modules what will happen if I do not use cursor WITH HOLD option, (I know it maintains the cursor position) and what if I directly load into E_T_DATA from my internal table. How this will affect the datapackage size?
In the future I will have records beyond 1 million and I am concerned to send all the 1 million record in one package rather than multiple packages during extraction.
Please give a solution if you have come acroos this kind of situation with your development.
Thanks,
Alex.

Alex,
I do not see why the complexity of ABAP statements should make you change the data processing logic proposed by SAP by way of the sample Function module.
It appears to me that you are changing something knowing fully well its implications and then trying to find a solution for it.
Good Luck!
Mathew.

While in the functional module on the basis of RSAX_BIW_GET_DATA_SIMPLE ' has made the following
* Data transfer: First Call      OPEN CURSOR + FETCH
*                Following Calls FETCH only
* íà÷àëî îáðàáîòêè
* First data package -> OPEN CURSOR
    IF S_COUNTER_DATAPAKID = 0.
delete from zdbasetable1.
import inttable1 inttable2 inttable3 from database INDX(IM) ID 'IDENT'.
loop at inttable1.
move-corresponding inttable1 to zdbasetable1.
modify zdbasetable1.
clear zdbasetable1.
endloop.
      OPEN CURSOR WITH HOLD S_CURSOR FOR
      SELECT (S_S_IF-T_FIELDS) FROM zdbasetable1.
    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.
But it would be desirable, without use database table - zdbasetable1

Functional Module Extractor not pulling all the record on BW side

Hi,
i have written a FM extractor to pull data from CDHDR and CDPOS table. the Records count shows on RSA3 is more than 3,00,000 but while pulling it on BW side it brings only 41,000 Around records.
I steps i have taken is -
tried setting and resetting the package side in Info package.
Tried putting the default package size to 50K in FM setting
but nothing is working.
It seems like the pacet size is not incrementing in the code. i have tired to find ou the fault but coult not and RSA3 is working fine.
can anyone please suggest a correct piece of code or find out where exactly the fault is?

Vikrant,
The structure of your generic extractor function module should be something like:
If initialisation
Store parameters, clear packet count
Else
If first packet
Create cursor
Endif
Read block of records from cursor
If cursor returns no more records
Raise NO_MORE_DATA exception
Endif
Process records from cursor and output
Add one to packet count
Endif
This function module code can get called repeatedly. Possibly you are only extracting data for the first packet?

Fields inclusion for Function Module Extractor

Hi Gurus,
I am planning to design a Function Module based extractor. This Function modules is supposed to extract data from approx 10 different tables. Most of the tables have 5 or more fields of it to be pulled in.
However, there are also few tables, which have got just a single field or just 2 fields.
As a design, is it a good idea to include the logic of extracting these fields in the Function module? or
Is it recommended to have these fields included via a user exit, once the datasource is developed?
I appreciate all the help

Thanks Dash I have assigned the points.
I guess you are recommending the User Exit approach as mentioned in my original post where few of my tables have got just a single field or just 2 fields.
Let me know please.
Other SDNers,
Let me have your thoughts too

Function Module - Generic Extraction : Not able to solve

Hi Guys,
       I have created a function module. The function module is working well. But when i start the extraction. It does not stops. It starts loading same data package again and again. It is becoming an endless loop. I have ot ask basis person to kill that job. He inturn has to restart SAP r/3 server. This has become a big issue. Guys please help I am attaching the code for your reference
Example: DataSource for table SFLIGHT
TABLES: YSALES,
       MBEW.
DATA: BEGIN OF I_YSALES OCCURS 0.
          INCLUDE STRUCTURE YSALES.
DATA: END OF I_YSALES.
DATA: BEGIN OF I_MBEW OCCURS 0.
          INCLUDE STRUCTURE MBEW.
DATA: END OF I_MBEW.
Auxiliary Selection criteria structure
DATA: L_S_SELECT TYPE SRSC_S_SELECT.
Maximum number of lines for DB table
STATICS: S_S_IF TYPE SRSC_S_IF_SIMPLE,
counter
          S_COUNTER_DATAPAKID LIKE SY-TABIX,
cursor
          S_CURSOR TYPE CURSOR,
          S_CURSOR1 TYPE CURSOR.
Select ranges
RANGES: L_R_ZYEAR FOR YSALES-ZYEAR,
          L_R_ZMONTH FOR YSALES-ZMONTH.
Initialization mode (first call by SAPI) or data transfer mode
(following calls) ?
IF I_INITFLAG = SBIWA_C_FLAG_ON.
Initialization: check input parameters
                buffer input parameters
                prepare data selection
Check DataSource validity
   CASE I_DSOURCE.
     WHEN '0SAPI_ysales_SIMPLE'.
     WHEN OTHERS.
       IF 1 = 2. MESSAGE E009(R3). ENDIF.
this is a typical log call. Please write every error message like
*this
       LOG_WRITE 'E'                  "message type
                 'R3'                 "message class
                 '009'                "message number
                 I_DSOURCE   "message variable 1
                 ' '.                 "message variable 2
       RAISE ERROR_PASSED_TO_MESS_HANDLER.
   ENDCASE.
   APPEND LINES OF I_T_SELECT TO S_S_IF-T_SELECT.
Fill parameter buffer for data extraction calls
    S_S_IF-REQUNR    = I_REQUNR.
    S_S_IF-DSOURCE   = I_DSOURCE.
    S_S_IF-MAXSIZE   = I_MAXSIZE.
Fill field list table for an optimized select statement
(in case that there is no 1:1 relation between InfoSource fields
and database table fields this may be far from beeing trivial)
    APPEND LINES OF I_T_FIELDS TO S_S_IF-T_FIELDS.
ELSE.                 "Initialization mode or data extraction ?
Data transfer: First Call      OPEN CURSOR + FETCH
               Following Calls FETCH only
First data package -> OPEN CURSOR
   IF S_COUNTER_DATAPAKID = 0.
Fill range tables BW will only pass down simple selection criteria
of the type SIGN = 'I' and OPTION = 'EQ' or OPTION = 'BT'.
    LOOP AT S_S_IF-T_SELECT INTO L_S_SELECT WHERE FIELDNM = 'ZYEAR'.
      MOVE-CORRESPONDING L_S_SELECT TO L_R_ZYEAR.
      APPEND L_R_ZYEAR.
    ENDLOOP.
    LOOP AT S_S_IF-T_SELECT INTO L_S_SELECT WHERE FIELDNM = 'ZMONTH'.
      MOVE-CORRESPONDING L_S_SELECT TO L_R_ZMONTH.
      APPEND L_R_ZMONTH.
    ENDLOOP.
Determine number of database records to be read per FETCH statement
from input parameter I_MAXSIZE. If there is a one to one relation
between DataSource table lines and database entries, this is trivial.
In other cases, it may be impossible and some estimated value has to
be determined.

Hi Baljit,
This is a dangerous way of extracting your data.
I am not surprised that it has become an endless loop.
You have to use the cursor and the fetch statement and after the fetch statement you have to use a subreturncode
to wonder if the fetch statement did get any data.
if not use the folowing statements.
close cursor s_cursor.
raise no_more_data.
In your situation the select statement will start every time from the first record in the table ysales because you don't use the cursor. By using the cursor and the fetch statement, the fetch statement will start from the cursor everytime it calls the function module.
I guess this function module is part of an endless loop and will be exited at the moment that the function module returns with raise no_more_data. (in other words, the cursor is at the last record of the table ysales, so no more records will be found)
Hope this will help

Enhancing Function Module Extractor

Is it possible to enhance an extract structure which is using a function module as an extractor.
Basically I want to extract some more fields which the function module is not extracting. Can someone let me know how to do this.
Best Regards,
James.

hi James,
is it generic extractor or business content ?
if generic extractor, since it's our own, you can add field(s) in extract structure and add code in the function module to populate these fields.
go to transaction RSO2, and you will see the extract structure, use SE11 to 'change' the structure and activate. then add code in function module, use SE37.
if business content, RSA6, choose your datasource and double click the extract structure and click 'append structure', add field(s) with prefix ZZ. activate the structure.
and populate the field(s) via user exit ZXRSAU01 (for transaction data).
hope this helps.

Function Module Extractor with Delta Functionality

Hi Friends,
I have to extract the entire data of CDPOS table in R/3 , as its a cluster table I am unable to build a view, I am planning to go for FM extraction, Could someone help me as how to build it with Delta Functionality.
I think I need to develop the Datasource, with Extract Structure,( Do I need to create a Structure in SE11) Please help me out .
Thanks,
Krish

Hi,
you can either use an existing structure or else create one on your own. (SE11).
The DeltaHandlig fairly easy.
When having finished the extractor (FunctionModule, Structur and DatasSource), go to the "generic Delta" button and select the relevant field.
The Generic Delta and its DeltaPointer is managed within the DeltaQueue (RSA7) and works more or less like a selection. Don't think too hard about it in your function module except taht you need to select by this field in your FM.
Did that come clear?
