3 generic data sources or only one function module

Hi all,
I have 3 custom tables
1. ZCOUNTRY (giving the link between code entity and country)
1. ZCURR (giving the link between code entity and currency)
1. ZYTPE (giving the link between code entity and type entity)
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:

How to give only one function module execution Auth for a User ?

Dear Experts
I have reviewed S_DEVELOP auth object. It is not ful filling my requirement
Any Ideas !!
Rgds

Rakesh...Firstly thanks for reply.
As i said i reviewed these and found it is not meeting my requirement.
As we aware We can control auth to Function modules thru object type
Filed OBJTYPE----
FUGR --> 1st control
and with Function Group Name
Field OBJNAME----
<Function Group Name> --> 2nd control
In my scenario - I have given the authroizations as below
++++++++++++++++++++++++++++++++++++++++++++++++++++
ACTVT            Activity                                                 Display, Execute
DEVCLAS       Package                                               *

P_GROUP       Authorization group ABAP/4 pro              *
++++++++++++++++++++++++++++++++++++++++++++++++++++
The above authroization is giving all Function modules authrozation under ZECC_FG Function Group.
My Requirement
I shoudl be able to give only one Function Module of a Function group where multiple function modules exist under the same Function Group.
How can i acheiveit. Any Custom Control can be place to acheive this.
I am sure S_DEVELOP will not solve my requirement (I Beleive)

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 Enahncement

Hi All,
I have to add two field from a Z*table in source system into an existing Generic Data Source based on a functional module.
What should be the approach ?
Kind regards,
Tapish

Hello Tapish,
You would have to change the extract structure to include the new fields. Also, you have to change the coding in the funtion module to extract the fields. Then replicate the datasource to the BW system.

Vincent

Error in Using Generic Data Source

Hi,
I have created a generic data source which uses a function module and replicated in the same system for testing. Now when I try to create a infopackage and load data into PSA, I am getting a short dump. Please help me out as I am very new to this.

Hi,
in order to get some help you need to provide the information of the short dump as it can have multiple reasons. So please give us a more detailed error description.

Generic Data Source Creation (Very Urgent)

Hi Friends,
I am getting errors while i am creating Generic Data source using Table "ECMCT" .This table contains all fields which is required for my Data Source.
---> I gave <b>ECMCT</b> table in "Extraction from DB view " but when i click save its showing error message "INVALID EXTRACT STRUCTURE TEMPLATE ECMCT OF DATASOURCE ZFI_ECMCT(is name of my data source)".
> I created Function Module using this Table.
In Function Module "Tables tab"
i gave "ITAB LIKE ECMCT".
In "Source Code tab"
i gave "SELECT * FROM ECMCT INTO TABLE ITAB".
In RSO2 "Extraction Using Function Module"
i gave FM name and Extract Structure name as ECMCT. After clicking save its showing ERRORS:
1) ZFI_ECMCT(is my data source name) : Tables parameter E_T_DATA for Extractor ZFI_CONSOLIDATION(is my Function module)
2) Units field CURR1 for feild HSLVT of datasource ZFI_ECMCT is hidden.
3) ......................................HSL01.....................................................
4)........................................HSL02...................................................
;etc.
Could u anybody suggest me where i am doing wrong. This is very very urgent for me.
Thanks,
Mani.

Hi,
For " Extraction Using Table" the system does not create an extract structure automatically if the Amount field (type CURR) and currency key field (type CUKY ) are in different tables . Hence u create a View of the data table and the reference table (Say PA0002 and T001) wherein, include all the fields from PA0002 and just the referenced fields from T001 so that all the fields come under the view.
But if the above solution is not possible say for ex. if the key fields don't match , then u should go for function modules.

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.

FUNCTION MODULE CREATION FOR GENERIC DATA SOURCE

Hi BI gurus,
I am creating function module for generic datasource. For that I followed below mentioned steps
Steps
1.     Created s structure with the fields that needed.
2. Created FM by copying the standard Function module
" RSAX_BIW_GET_DATA_SIMPLE " and Give a New name starting With
Y or Z .
3. IN SE37 ->Your Function module name -> Change, In table tab given structure
name by deleting the associated type given in E_T_DATA .
And inserted the required code given below
      PROGRAM 'ZHU_BALANCE'.
*& Report ZHU_BALANCE
TABLES: VEKP, VEPO.
DATA: BEGIN OF T_DISPLAY,
      DATE   LIKE SY-DATUM,
      EXIDV LIKE VEKP-EXIDV,
      LGORT LIKE VEPO-LGORT,
      WERKS LIKE VEKP-WERKS,
      END OF T_DISPLAY.
DATA: ITAB_DISPLAY LIKE TABLE OF T_DISPLAY.
DATA: WA_ITAB_DISPLAY LIKE LINE OF ITAB_DISPLAY.
SELECT VEKPEXIDV VEPOLGORT VEPO~WERKS
       INTO CORRESPONDING FIELDS OF TABLE ITAB_DISPLAY
       FROM VEKP AS VEKP INNER JOIN VEPO AS VEPO
         ON VEKPVENUM = VEPOVENUM

         AND VEKP~STATUS = '0020'
         AND VEPO~VEPOS = '000001'.
LOOP AT ITAB_DISPLAY INTO WA_ITAB_DISPLAY.
WA_ITAB_DISPLAY-DATE = SY-DATUM.
MODIFY ITAB_DISPLAY FROM WA_ITAB_DISPLAY TRANSPORTING DATE.
ENDLOOP.
WRITE:/ 'DATE', 20 'EXIDV', 40 'LGORT', 60 'WERKS'.

WRITE:/ WA_ITAB_DISPLAY-DATE, 20 WA_ITAB_DISPLAY-EXIDV , 40 WA_ITAB_DISPLAY-LGORT, 60 WA_ITAB_DISPLAY-WERKS.
ENDLOOP.
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
Regards,
praful

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

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,

More than one field in generic data source

Hi All,
We wanted extract Allocation data for the sales order from R/3 to BW. I am not able to find proper data source for it... there are two datasources..we wanted afs specific datasource
2LIS_11_V_ITM : Sales-Shipping Allocation Item Data
2LIS_11_V_SCL : Sales-Shipping Allocation Schedule Line
But its not reflecting allocated quantity at all...
So we decided to create generic data source.. but there is one problem for some allocation ARUN is initial.. so i cann't use ARUN as delta field... can i use comination of Sales order no,Item and Schedule line number as delta field....
Because in RSO2 i can define only one field as delta specific field....
How to proceed ???
Regards,
Viren.

Hi,
If you decided to use generic data source, make sure that, U'll have to take only
one filed as a delta, I suggest, you take any date field rather than the value fields
it may be created date/change date and so on so forth..

Pattan.

Design Studio 1.3 : one large generic Data Source or multiple smaller Data Sources

Dear all,
In DS 1.3, is it still a best practice to have one large generic Data Source ? Or is having multiple smaller Data Sources a better solution ?
Minimizing the number of Data Sources remains a golden rule, but what is the best solution :
One large generic Data Source : and using setDataSource
or
Multiple smaller Data Sources : and using Load in Script and Background Processing
Many thanks for sharing your ideas,
Hans

It depends on your application and how much the data is pulling in and how you want to present that to the user/consumer of the application.
At TechEd Las Vegas last year, SAP showed a 9 dashboards (3 per row) with background processing for each row.

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...............

Hi,
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.
Thanks,

Error while testing Generic Data Source extraction

I've created generic data source for Texts and Attributes in R/3 based on VIEW (Z table)
I get error "Error 6 in function module RSS_PROGRAM_GENERATE" while trying to test the data sources through RSO2
I guess there can be a lot of reasons... Please name me anybody who knows them...
thanx in advance

Hi,
Please Check the OSS note 328948 and it provides solution to same error what you have. Additionally you can have a look into this OSS note 705212 too.
Syntax error in the generated extraction program Symptom
You notice the error by one of the following symptoms:
The loading of transaction data from an R/3 system terminates with a syntax error in the generated extraction program. The monitor displays the error messages:
R3027 "Error & during the generation of the data transfer program"
RSM340 "Error in the source system"
The extraction within the extractor checker terminates with error message RJ028 "Error 6 in function module RSS_PROGRAM_GENERATE".The activation of transfer rules ends in BW with error message RG102 "Syntax error in GP$ERR$, row... (-> long text)" from the source system. Usually, the diagnosis in the long text of the error message is: "...could not be interpreted. Possible error causes: Incorrect notation or... "
Other terms
OLTP, extractor, data extraction, DataSource, Service API, SAPI,
R3 027, R3 27, RSM 340, RJ 028, RJ 28
Reason and Prerequisites
The error only occurs in the source system, if this contains Basis Release 3.1I and Service API (SAPI) 3.0C Support Package 6. SAPI 3.0C Support Package 6 is contained, for example, in PI 2003.1 Support Package 7 (see attached composite SAP note 673002).
Solution
To correct the problem you need service API 3.0C Support Package 7 in the affected source system. The attached composite SAP note 704971 explains in which software components service API 3.0C is contained, and what the corresponding Support Packages of these components are.
Alternatively, you can also copy the advance correction from the appendix.
Hope it helps.
Regards
