How to control iteration of function module in generic extraction to BW

Hi Experts,
I am customizing standard Function module RSAX_BIW_GET_DATA_SIMPLE. My problem is, while excecuting datasource in RSA3, my function module is repeating many times.....example if my FM fetches data of 70 records.......FM is repeating 70* n times while executing it in a data source.
How to contol this loop?
Can anyone please help me.

Hi,
This FM is used to get list of files from Application server (will work in Background). This cannot be used to list files from presentation server. There is no way , by which you can process presentation server files in background mode.

When we go for Views and Function Modules for Generic Extraction

Hi Experts,
Can you please explain when we go for extracting the data using Views and when we got using Function Modules using Generic Extraction from R/3 system to BW with examples. And also can you explain when we go for delta for the above both scenarios.
Thanks for you help in advance
Rohith

Hi,
Scenario for Extarction using FM
Imagine the scenario where you need to extract data from
tables having no common field between them and thereby preventing you from creating a view on top of those tables..
Or simply consider tables that are highly unrelatd in terms of fields, but you have a requiremnt to extract data from them.

Scenario for Extraction using View
If there are more number of tables and data in those tables can be represented using joins then we can use this type of extraction

How to control sequence of Function Modules processed in update task?

Hello,
I've some questions regarding following process that needs to be extended: a Function Module (FM) 'Save' calls several other FM e.g. 'X1' and 'X2' in update task. Those update modules are independent from each other and write data to the database that finalize the save process.
Now a third FM 'X3' needs to be called in update task. This one is also independent from 'X1' and 'X2' but it calls a further FM 'X4' in background task as separate unit which starts a job. This job requires the data from FM 'X1' and 'X2' already persistent on the database. By the way: the FM 'X3' triggers the Access Control Engine (ACE) notification that calculates the authorization data in the mentioned job. Therefore this process needs to be the last FM call in update task in the queue of calls in FM 'Save'.
Questions:
(1) Is it possible to control the process sequence of the FM 'in update task' simply by the sequence they are called in FM 'Save'.
(2) Presumed that all FM beside 'X3' have processing type "Update with immediate start" or "Immediate start, no restart" (in short V1) would it be another solution to specify FM 'X3' with type 'Delayed' to control the process sequence? When a delayed FM will be processed?
(3) Is it uncritical to call in FM 'X3' (already running in update task) the FM 'X4' with addition in background task as separate unit that furthermore starts a job by an event? I'm afraid that this nesting could lead to unexpected errors.
Thank you in advance for your help!
Best regards,
Oliver

ya it will this be in the same sequence only...........

Help on Function module in Generic Extraction

Hi ,
i am writing FM in for Generic Extraction.
i am dont know ABAP.
i am using RSAX_BW_GET_DATA_SIMPLE..
i created Strcture from the MVER table ..
Strcture fileds : MATNR
                       GJAHR
                       GSV01,
                       GSV02,
                       SUM.
SUM is not in the MVER table .
Pl . give me code for this logic ..
Logic :
Take sum of GSV01 , GSV02 from table MVER with the key
                   MVER-MATNR = MARA- MATNR and
                   MVER-GJAHR = Year from SY-DATUM.
Pl . give me code for this logic..
i assign points ..

Hi Diego Lombardini ,
thanks for fast reply..
i retrieve fields from 6 tables , thats why i choose function module but
my main logic mention above .
i created view but it gives wrong values bcoz lot of joins .
so i decide FM is better option ..
Pl . provide code for this logic ..

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 *
OBJNAME Object name ZECC_FG
OBJTYPE Object type FUGR
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)

How to create EXCEPTION in function module

hi experts,
          how to create exeptions in function module i want step by step.
regards,
chaitu

hi,
Raising Exceptions
There are two ABAP statements for raising exceptions. They can only be used in function modules:
RAISE except.
und
MESSAGE.....RAISING except.
The effect of these statements depends on whether the calling program handles the exception or not. The calling program handles an exception If the name of the except exception or OTHERS is specified after the EXCEPTION option of the CALL FUNCTION statement.
If the calling program does not handle the exception
·         The RAISEstatement terminates the program and switches to debugging mode.
·         The MESSAGE..... RAISING statement displays the specified message. Processing is continued in relation to the message type.
If the calling program handles the exception, both statements return control to the program. No values are transferred. The MESSAGE..... RAISING statement does not display a message. Instead, it fills the system fields sy-msgid, sy-msgty, sy-msgno , and SY-MSGV1 to SY-MSGV4.
Source Code of READ_SPFLI_INTO_TABLE
The entire source code of READ_SPFLI_INTO_TABLE looks like this:
FUNCTION read_spfli_into_table.
""Local Interface:
*"       IMPORTING
*"             VALUE(ID) LIKE SPFLI-CARRID DEFAULT 'LH '
*"       EXPORTING
*"             VALUE(ITAB) TYPE SPFLI_TAB
*"       EXCEPTIONS
*"              NOT_FOUND
SELECT * FROM spfli INTO TABLE itab WHERE carrid = id.
IF sy-subrc NE 0.
    MESSAGE e007(at) RAISING not_found.
ENDIF.
ENDFUNCTION.
The function module reads all of the data from the database table SPFLI where the key field CARRID is equal to the import parameter ID and places the entries that it finds into the internal table spfli_tab. If it cannot find any entries, the exception NOT_FOUND is triggered with MESSAGE ... RAISING. Otherwise, the table is passed to the caller as an exporting parameter.
Calling READ_SPFLI_INTO_TABLE
The following program calls the function module READ_SPFLI_INTO_TABLE:
REPORT demo_mod_tech_fb_read_spfli.
PARAMETERS carrier TYPE s_carr_id.
DATA: jtab TYPE spfli_tab,
      wa   LIKE LINE OF jtab.
CALL FUNCTION 'READ_SPFLI_INTO_TABLE'
     EXPORTING
          id        = carrier
     IMPORTING
          itab      = jtab
     EXCEPTIONS
          not_found = 1
          OTHERS    = 2.
CASE sy-subrc.
WHEN 1.
    MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno.
WHEN 2.
    MESSAGE e702(at).
ENDCASE.
LOOP AT jtab INTO wa.
WRITE: / wa-carrid, wa-connid, wa-cityfrom, wa-cityto.
ENDLOOP.
The actual parameters carrier and jtab have the same data types as their corresponding interface parameters in the function module. The exception NOT_FOUND is handled in the program. It displays the same message that the function module would have displayed had it handled the error.
Hope this is helps,Do reward.

How to create a callback function module

Hi all,
I am working in a requirement where we need to call a function module at a 'after change' event. So how to create a callback function module and register it with the crmvevent ?_
I created a sample function module and try to create entries in table crmv_event_cust, but i got an error message saying that the function module name I provided is not in table CRMC_FUNC_ASSIGN. When I try to create entry there, I got a message that function module is not in CRMC_OBJ_FUNC and that table is a standard table with no maintanance options !!
looks like i am going in wrong way ... can any one please help ??

Looking at my system all you need to do is create the entry for the callback function in maint view: CRMV_FUNC_ASSIGN.
Your entry should be as simple as Z-function name Object Function - <same as others in the segment you are assigning>
IE for the partner it would be CRM_PARTNER as object function, for general order processing CRM_ORDER
Take care,
Stephen

How to check for a function module with its description and functionality

Hi all,
How to check for a function module,with its description and its functionality,in detail how can I know the purpose of a particular function module,how to search for a function module which suits my requirement .

Hi,
You can search a FM of your requirement by putting in the Key words and searching for a FM. Like * KEYWORD * and then pressing F4.
Say for example you need to search something regarding converstion.
Search for * CONVERT * and press F4.
If there is something specfic like converting date to something you can give
DATE * CONVERT *
OR
CONVERT * DATE * and press F4.
Once you narrow down your search you will have a Function module documentation inside the Function module. Please note that all the FMs willl not have documentation.

Pramod

How to connect our outbound function module to the message type

how to connect our outbound function module to the message type any transcation code exits to assign the message type with the function module .
Thank in advance .
A. Thiru

Hi Thiru,
Standard Transaction Codes, have their own Function Modules for generating Outbound/Indbound Idocs. Where these Function Modules will be configured to a particular Process Codes.
For E.g for PO's
Process code : ME10 - IDOC_OUTPUT_ORDERS - for creation
In case if its a Z Function Module, It depends on the case how you use IDOC types. either directly through Z Program or through Inbound/Outbound Process codes with respective Function modules.
