Error in Data selection in R/3 Generic Extraction Using function Modules

Hi Friends,
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
data selection successfully started
Data selection successfully ended
All Data packets completed.
are showing in red.
after and hour time load getting failed and in the error message it is showing " job terminated in source system---> Request set to red"
it is giving this message wir no RSM 78.
Please let me know it

Hi Jerry,
Thanks for the immediate replay
But here in my source system job is getting terminated.
this is the status of job in Job logs.
the job is running till this step not going ahead.

Generic Extraction using Function Module

i want to know the step by step procedure for this extraction and also why we need to go for this, i mean in which scenario this is the best method. and do we need to write any abap code for doing this.and also i need what alla transaction codes we use including concepts.

1> I don't have a step by step procedre doc. But, there is a sample fucntion module, RSAX_BIW_GET_DATA_SIMPLE. You can take a look at this to create urs.
2> It is an alternative to the of using InfoSet query (using ABAP datasource) where you cannot split the data to be extracted into DataPackages. So, it is very helpful for huge extracts.
3> Yes, you have to write ABAP code for this.
4> Transactions used.
Create function module - SE37
Create DataSource using FM - RSO2
that is all!

Urgent: Problems in Generic Extraction by Function Module

Hi BW Gurus,
I am new to SDN and also new to generic extraction using function module. My requirement is to extract long text(142 char) from CRM to BW as the text is not stored in database table I used function module read_text with in another ZXXX function module copy of (RSAX_BIW_GET_DATA_SIMPLE). In my extract structure I used GUID(char,32), Langu, long text(142 char) and 2 placeholders. Text can be extracted by passing STXH table fields(Tdname, Tdid, Tdobject, Tdspars) to read_text as parameters and i also need to use CRMD_ORDERADM_H field GUID(32 char) to compare 1st 32 chars of tdname(70 char) with Guid to select Guids and loop thru this Guids and for each Guid i need to append lines of text to e_t_data but as i donot know ABAP i unable to write the code for this. Through my friends help i wrote code when i check in RSA3 it is displaying the text but when i replicate into BW and load into data target in monitor the status is red with records initially but afterwards it will be red status again with 0 from 0 records for initial load again.when i check on job logs the errors i have are:
The background job has created a job log file of 2Gb size and it is currently on a infinite loop writing entries into the SAP System Log that it cannot write to the Job log file due to Error 22 for write/read access to a file this is because of the datasource i have created. Please find my Function module and if anyone would please correct FM and send me that will be really great.I appreciate it in advance.
MY Function Module is:

Hi,
The statement <b>RAISE NO_MORE_DATA</b> should be active (uncommented) in your code. Otherwise, the infinte loop occurs.

3. Create the data source using transaction (RSO2).
4. If structure exists for the table parameter of your function module then ok else create a structure for the table parameter E_T_DATA.
5. Test the datasource in R/3 using transaction RSA3.
6. Transfer the data source to BW System and replicate it in the BW-System.

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

Delta Extraction Using Function Module ( Customization )

Dear Experts,
I want a sample code for Delta Extraction using Function Module ( If it is customized already working code very helpful ), I have already created Function Module but Full update is happening. If I give delta update again it is retrieving all records. It is very urgent, if you have please send me to the following mail ID.

Hi SGK,
I've done this for a delta based on a timestamp and it's actually pretty easy. The basic steps are:
1) Create an extract structure in SE11. Make sure the structure has a date or timestamp field in it that you can use for delta. You'll need to include the field twice if you also want to extract it to BW/BI since once it's chosen as the delta field then it will be hidden in the interface.
2) Create the extractor function module in SE37. You can use RSAX_BIW_GET_DATA_SIMPLE as a template. Make sure your logic restricts the data it retrieves according to the selections that are passed in I_T_SELECT, including restrictions on the delta field.
3) Create a generic DataSource in RSO2. Click Extraction by FM then fill in your extract structure and function module. Click Generic Delta and pick your delta field and the appropriate radio button (time stamp or calendar day). If your delta field is a timestamp field then be sure to set the upper and lower safety limits to -86400 and 86400 respectively. This might not be necessary on your version of SAPI but on mine there is a bug where it doesn't translate between system time and UTC (GMT) correctly so this was necessary.
You don't need to program any special delta handling logic in your function module as long as you restrict the data you retrieve based on the delta field (I_T_SELECT). This is because the SAPI takes care of catching the init, delta and repeat requests, translating them to the appropriate delta field values, and then passing them to your function module as if it was a full extraction for a specific date or timestamp range.
Hope this helps!

Dear KJ,
Thank for your response. I saw the code that you sent, you have used some ztables like ZSC_DELTA_IP, ZSC_SAFETY_DELTA, ZSC_SET_EXT_TIME
What are the fields that you have created in these tables , what is use of these tables, can you send the fields that you have used in these tables.
Thanks & 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
Thanks

The 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 ?
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.
