Generic Data source on Function module

Hi All,
We are working on generic data source based on a function module for the first time and we do not know how to start with.
Our requirement is to fetch mode of communication field from SRM. We have identified a function module in SRM which does this job. But when we try to create a generic data source on this function module it is throwing an error.
Are the import parameters for a general function module and function module for a BI generic data source different?
If so could someone please guide us in creating the function module so that we can create a generic data source on top of it.
The function module should serve the same purpose as the function module BAPI_BUPA_ADDRESS_GETDETAIL.
Thanks,
Shravani

Shivani,
My suggestion would be creating Z-program to store the values in a custom table and use this for extraction.
Further if still want to use the FM itself, post the error details you are getting.. or try to analyse the FM and find the base table so that you can directly use in extraction.
Hope this helps,
anil

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.

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,

Creation of Generic Data source using function module based on the program which was used to created ABAP report

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,
Ravi

Hi,
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

BC data source and functional module

Hi Gurus
I know that we can extract data via functional module in case of generic extractor but when we use business content data source ( for ex.0MAT_PLANT_ATTR) is it possible to use functional module to extract the data?
How can we find the functional module? my requirement is I need to enhance this data source with few more attributes.
Pl help. also advise where I need to write the code?

You can see if it FM based or not, in RSA2, or, in table ROOSOURCE (on the source system).
In general, it is not possible/advisable to change the BC extractor FMs.
Right way to go about is to use enhancements. For this case 0MAT_PLANT_ATTR, if the other attributes are coming from same material tables, you may be able to get those by enhancing the extract structure.
If not, you can enhance the extract structure, and write the code in the user-exit provided for extending master data extraction (function EXIT_SAPLRSAP_002 - check its documentation in SE37).

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

Regarding: Loading data from R/3 To BI for a Generic Data source

Hi Every,
Need Help Urgent
I had created a Generic data source with function Module as the data source, in Rsa3 it is working fine.
1-> I had replicated the data source to Bi then i had created a info package and then I executed the same. when it is getting the data and it is show in the request monitor (Number of records ) but the status is not changing from Yellow to Green.
Status in Step by step analysis is every step is green Except "Data selection successfully finished ?" (RED)
2-> Then I had seen the Back ground job in Source system which is executing still. I waited for it for a long time but nearly 30 min.
(I had done Steps one and 2 number of time by activating replicating the data source and so on, but still their is no change in it)
3-> Then I had canceled that back ground job with the help of BASIS (as i feel that it is something going wrong).
4-> I feel that their is some thing wrong in the Code of Extractor.
Please Help...............

Please check the log of same jobs for last week and check is today its taking more time,also check with basis is their any backup initited at same time.
Moreover until the background job failed automatically its difficult to imagine what is the exact issue.

Generic Data Source issue in CRM.

Hi Guru's,
Generic Data Source with Table gave an issue "invalid Extracture structure template XXXXX of Data source XXXXX"
Generic Data source with Function Module gave an issue "Units field VOLUM_U for field VOLUME of DataSource ZTEST_XYZ is hidden"
Generic Data Source with View configured successfully but the data is not coming in Extractor Checker.
Three tables has taken in to consideration. I think there might be some issue with Join condition.
Can any one through light on this incident. Your help will be appreciated.
Thanks in Advance.
Venkat.

Hi Praveen,
yes you are right. I took reference field as VOLUM_U.
I have created Generic Table. Do you need me to take same table in the reference Table.
Thanks
Venkat.

Generic Data Source is calling multiple times in RSA3

[color:red}<Moderator Message: This topic has alread been discussed a lot of times. Additionally there are weblogs related to it. Please search the forums and/or the blogs for this issue>
Hi experts,
I have the requirement to get data from Generic Data Sources with function Module,
after finishing the FM I have checked in extact checker(RSA)
in the internal table I_T_DATA is displays 281 records,
but in RSA3 it shows 112560 records, I found that the FM is calling multiple time by executing one time in RSA3.
1.what would be the problem
2.where is the porblem is it in FM coding or any other places to check.

Hi Savita,
I don't understand clearly from your reply regarding flow you transported and what all you transported.
You need to first transport objects in R/3 and import them.
Then transport Infoprovider, Datasource in BI assuming depenedent Infoare Infoobject, application component already transported.
Then transport your Infosource, Update rule, Transfer rules, Infopackage.
Hope you understood.

Delta Enabled Generic Data Source

Hi All,
I have created one Delta Enabled Generic Data Source with
Function Module. The Delta field is Date Field. The Data source picks data from R3 to BW.
In RSA3, I executed the Extractor with the Delta Type "C" i.e Delta Initialization ... but it is throwing the error "Errors occured during the extraction". I also checked the Display Log and the error message is "Could not determine BW release of logical system".
Moreover I am not able to see the Delta Attributes in
RSA7. I checked with the other delta enabled generic extractors which uses Views .. is found to be working fine ... and I also able to see the Delta Attributes in RSA7.
Any suggestions?
Bye
Dinesh

Dinesh,
Once you have generated transfer rules in BW for the datasource, delta init can be tried out in RSA3. It iwll not create the delta queue though. Only test the initialization.
To do this, once you have created the transfer rules in BW, specify the logical system name of the BW system in the target system field. After that the extractor can be run in RSA3. It is flagged as read only so delta queue will not get created.
Cheers
Aneesh

While checking the function module its populating the syntax error as
THE TYPE SRSC_S_IF_SIMPLE IS UNKOWN. (Though this is commented in program)
So pls suggest

hi indira,
thanx for ur reply we have created the funcion module successfuly it is also showing the output correct. But when we put that function module in the generic data source and try to extract data in RSA3 it shows the correct output of function module but with the msg ' 0 entries found in customer enhancement' and therfore zero records in the display list.
is there any correction or steps to be followed in data extraction
pls suggest

Function modules transfer repeated records in Generic data source

Hello Friends ,
I have created a FM to extract the data from fields of tables BKPF and BSEG .
This functional module is used in the Generic data source.
Now if I check in RSA3 for this Generic data source,
the records are coming 10 times instead of a single time.
Means one records at data base table is showing ten records in RSA3.
Any help please.
Regards,
Amol.

Hi Amol,
Can you please check the Fetch statement that you are using after opening the cursor and selecting data into it. It should be in the format below.
FETCH NEXT CURSOR S_CURSOR APPENDING CORRESPONDING FIELDS OF TABLE E_T_DATA PACKAGE SIZE S_S_IF-MAXSIZE.
Also are you incrementing data package ID or not by using the statement
S_COUNTER_DATAPAKID = S_COUNTER_DATAPAKID + 1.

I shall fill an info object which has as fields code entity, country,currency and type entity.
I have 2 solutions i suppose:
1. Create 3 generic data sources based on the 3 tables.
2. Create a generic data source by using the function module.The function module will populate an extract extracture from data from these 3 tables.
What is the best solution?What is the advantage of the chosen solution?
Thks a lot.

Hi,
Generic Extractors are based on View/Table or Fn Module or Infoset Query i.e all the extractors created via RSO2. The extractors you create for the customers would generally be generic extractors only. SAP has some other extractors like your LIS, LO Cockpit which are based on different extraction method.
Generic extractors are of 3 types:
1. Based on table/view
2. Based on Infoset Query
3. Based on Function module
The first 2 are straight forward extraction where you would either use a standard SAP or custom table/view or Infoset query to extract data.
However if you have to get data from more than 1 table and also incorporate some logic then you would use a fn module extractor. It is like a program where you would code using ABAP and have all your logic incorporated.
Check this blog for more info on fn module extractor:

Generic Data Source Based On Function Module (Delta capable)

Hi,
My requirement is to develop a Generic Extractor based on Function Module (Delta capable). As I already found many threads explaining this concept, but most of them discussing FM RSAX_BIW_GET_DATA_SIMPLE with Extraction Method F2. There is another FM RSAX_BIW_GET_DATA which, one can use to build delta enabled extractor.
Although I do have some doubts:
what is the E_T_SOURCE_STRUCTURE_NAME ?
read table i_t_select into l_s_select with key fieldnm = 'PGMID'. Use of this code ?
Templet only showing
case i_updmode.
      when 'F'.
      when others.
        if 1 = 2. message e011(r3). endif.
        log_write 'E'                  "message type
                  'R3'                 "message class
                  '011'                "message number
                  i_updmode            "message variable 1
                  ' '.                 "message variable 2
        raise error_passed_to_mess_handler.
    endcase.
i.upmode as F, D(delta) is not included, do i need to include this?
Can someone help to solve this. Appropriate points will be allotted to helpful suggestions.

Try using following piece of code;
READ TABLE g_t_select INTO l_s_select
                             WITH KEY fieldnm = 'Date Field for Delta'.
      IF sy-subrc EQ 0.
SELECT SINGLE *
                       FROM ROOSGENDLM
                       WHERE oltpsource EQ 'DataSource Nameu2019
                       AND slogsys      EQ lw_slogsys.
          IF sy-subrc EQ 0.
            lw_date = roosgendlm-deltaid+0(8).
            lw_time = roosgendlm-deltaid+8(6).
                                                                                ENDIF.                       " IF SY-SUBRC EQ 0.
ENDIF.
OPEN CURSOR WITH HOLD S_CURSOR FOR
SELECT * FROM TABLE
                               WHERE CPUDT     GE   lw_date   AND
                                           CPUTIME GE   lw_time.
    ENDIF.
Table R00SGEMDLM stores the date and time data was last extracted from a data source.
Alternatively, you can also try using the i_updmode.
When 'F'.
SELECT * FROM TABLE (without any where clause on last change date)
When 'D'
SELECT * FROM TABLE
                               WHERE CPUDT     GE   lw_date   AND
                                           CPUTIME GE   lw_time.
These are just suggestions. Try these out, I hope it helps.
