Generic data extractor using function module
Hi All,
I want to create a generic data extractor using a function module within the BW system. i.e. the extractor will run in BW and and store the data in a cube( in BW). No R/3 is invloved. I proceeded as follows:
1. Created a structure through se11.
2. Created a function module. But while defining "E_T_DATA" in the "Tables" section of the function module, I am getting the error "TABLES parameters are obsolete". I defined as follows:
E_T_DATA TYPE ZBW_EXTRACT
ZBW_EXTRACT is the name of the structure.
What should i do in this case ?
Thanks,
Satya
Hi,
I went to se80. Copied the function module "RSAX_BIW_GET_DATA_SIMPLE" to my function group. When i tried to change the associated type from "SFLIGHT" to my own structure, it again gives a warning that "TABLES parameters are obsolete!". It does not allow me to either save, check or activate the function module. What should i do ?
Please reply urgently.
Thanks,
Satya

Hi,
We have a requirement to create a BI report based on plant maintenance report. The plant maintenance report is based on a ABAP program with complex logic. My question is i want create a Generic Datasource using Function module and can I include the logic(Abap Program) that is used for plant maintenance report in the function module? Please share your thoughts.
Thanks,
RaviHi,
Step1-Create a table structure which you need to create same as the fields you require in you data source.
Step 2-create a custom abap program and inside that call the Client abap program with the selections as required and save the result data in some table
Step 3-create infoset query.In the infoset query give your table structure name and program name which you developed.
Step4-create data source on top of that query -

SatyaHello Satya,
The message "TABLES parameters are obsolete" is just a warning and not an error. The structure of the interface is strict (defined by SAP). You should opt to proceed even if you receive the warning.
Hope this clarifies. -

Delta with Generic Extractor using function module
Hi,
I have created an extractor using function module and it work fine (mode FULL)
It's an extractor based on the FM RSAX_BIW_GET_DATA_SIMPLE.
In TCODE RSO2, I have specified a delta field (AEDAT).
In table ROOSOURCE, this extractor is defined by :
DELTA = AIE
EXMETHOD = F1
When I extract data in Init mode, there is no problem. But delta don't extract any entries.
When I trace with TCODE ST01, in Init mode the function module is executed but in delta mode, there is no trace of any use of this function module.
I don't know how to do to make this extractor work fine in delta mode.Hi Pascal,
The same function module i have used and succesffuly doing delta using it. So it works for both full & delta.
How ur testing it and where are you testing it for delta.
Do the delta testing through BI end. Set the
As u have already set the delta field., now Follow below steps:
1. First set the safety interval upper limit to -1, so that it will extract the delta data of 1 day back records also.
2. Please make sure wether the delta records are available or not in r/3, if there is no records to be fetched in for delta then u will not be able to track out wether delta is working or not.
3. Now do the init from BI end first. Delta initialization without data transfer. - It will give u green status with 1 dummmy record.
4. Now do the delta. It will extract the delta records.
Before that make sure that if any selection your giving in Infopackage should be met out by these delta records.
Thanks

Generic Data Source with Function Module data mismatch in BI
Hi All,
I'm using Generic Data Source with Function Module, When I execute the Function Module (Which I have Created), I'm getting 16000 records and when run extractor(in RSA3) im getting different no.of records(infact they are more no.).
when I run the InfoPackage in BI im Getting more no. of records than what i got executing the function module..
and single record is divided into 2 records in BI side(not all the records), how can it be possible???
is there anything Im missing to explain you my issue???
if understood please help me out.
Thanks n Regards,
ravi.the datasource frame work starts the function module several times.
1. the initialization
2. the serval times, until you "raise no_more_data".
check you coding: have you refreshed necessary internal tables.

ravi.HI rkiranbi,
1. FIrst you excute function module according to your paramers, you will get some records. then goto tcode RSA3 --> excute
Provide your Data source name and under setting we have options like Data records/calls, Display extractor calls and selections --> fields .
in that options you have to increase the values. and then you have to pass paramers in RSA3 according to your function module
selections in SE37. Now you will get equal values in both functin module selection and RSA3 Selection. if it fail means you need to
check coding logic in function module.
2. if your are getting wrong values in BI System then check with
1. compare with PSA data and data target data (here you need to check with characterstic as well as keyfigures)
if you find any mistake you need change the coding in function module according to client requirement.
2. compare data with RSA3 and bi report data or data target data.
check it properly above steps, you will get solution.
thanks and regards,

R/3 Master Data Extraction Using Function Module
Hi Experts,
Could you please let me know why & How (Detail procedure) to extract R/3 master data using function module.
My team manager asked me to extract master data from R/3 for 3 more attributes of info object '0material' which is already defined as data target.
I would like to know why they are extracting data using function module
ThanksThe steps for creating extractor using Function Module. I
1. Create new Function group (if you have already not done so) in Se80
2. Copy Function module "RSAX_BIW_GET_DATA_SIMPLE" with suitable name.
3. Change the code that populate data.
Following table may give you the guideline for parameters.
Parameter Description
I_REQUNR (import) BW provides this request identifier. It is a system-generated identifier in the form REQU_XXXXXX. BW uses this same identifier in all function module calls that relate to a single load.
I_DSOURCE (import) The name of the generic extractor
I_MAXSIZE (import) The maximum number of records that BW expects to be in each data packet
I_INITFLAG (import) A Boolean flag that indicates if this is the initialization (first) call to the function module
I_READ_ONLY (import) A test flag not needed in most extraction scenarios
I_T_SELECT (table) This table holds any selections from the BW InfoPackage. The function module should examine these selections and only return data that matches the selections.
I_T_FIELD (table) This table holds the fields that BW requests
E_T_DATA (table) The function module fills this table with data records. These records then return to BW as data packets. This table has the same structure as the extract structure defined in the generic DataSource.
NO_MORE_DATA (exception) The function module raises this exception when no more data is available
ERROR_PASSED_TO_MESS_HANDLER (exception) The function module raises this exception if an error occurred during the extraction. It alerts BW to check for error logs.
Change following code to put the selection fields
Select ranges
RANGES: L_R_CARRID FOR SFLIGHT-CARRID,
L_R_CONNID FOR SFLIGHT-CONNID.
Change following to populate data
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 ?

Delta Problem while extracting the data by using function module
Hi Experts,
I have extracted the data by using Function module, for delta loads I have given Calday and additive delta in Generic delta settings, in BW side I have initialized the data after that I have given delta update option in infopackage and I made process chain also, every day process chain is running successfully but it is showing zero records, but there is a data in Data source (RSA3), means delta is not working.
What is the problem,
Is there any another settings for delta loads,
Please help me to do this,
Helpful answer will be appreciated with points,
Regards,
VenkatHi,
Try this delta type :NEW STATUS FOR CHANGED RECORDS.
More information from Nagesh, this information may help
1. New status for changed Records.
2. Additive delta.
New status for changed records means
New Order
order no quantity
1000 10
order changed to quntity 8. then 2 records will posted 2 BW in first case.
1000 -10
1000 8
if you come to Additve delta.
for the same case it will send the same record as
1000 10
changed records
1000 -2
this is the difference. New status with changed records should be used only in association with ODS not cube becoz we don't have overwrite option.
Additive delta we can use for ODS and Cubes with update mode Addition.

How to extract the data by using function module?
hi experts,
what are the steps i have to fallow to extract the data from R/3 by using FUNCTION MODULE.
thanks & regards
venkatHi,
Extracting data from R/3 extract structure thru function modules
You can proceed with create function module using SE37, thereu2019s sample in system RSAX_BIW_GET_DATA_SIMPLE,
You need to know the logic how to populate the structure,
after that RSO2, create datasource specify extract structure and
function module,
activate and replicate to bw.

Generic Extraction By Using function Module with Three Table fields?
Hi,
I need to bring the data from three tables by using function module.
Tables: VBAK, VBAP, VBUK.

Hi Experts,
I try to create a generic data source using the transaction RSO2. I got the following error message
" Das Einheitenfeld CURR des Feldes ZPKZA1 der DataSource ZBWN_DS_POLPOSP ist ausgeblendet"
"The unit field CURR of the field ZPKZA1 of the DATA SOURCE ZBWN_DS_POLPOSP is not visible/ stopped/ hide".
How shall i handle this issue..........any suggestions please........
thanks in advance
Cheers
JayaHi Jaya ,
The error msg which is coming as...
"The unit field CURR of the field ZPKZA1 of the DATA SOURCE ZBWN_DS_POLPOSP is not visible/ stopped/ hide" may be due to the currency field made hidden at the data source lavel. Also check weather you have included it in your structure (code).
So, to check it and make it unhide go to "Display Field List (F7)" in RSO2.
Hope it helps.
