Function modules calling Application server

I am working on a SAP Migration for windows to unix. Right now I am patching up all custom programs which call the Application server using physical filenames and paths (platform specific) and replacing them with logical paths and names (platform independent). I need help from you guys to identify more function modules which uses file names that are platform specific. I have taken care of open dataset and FTP commands. Any help pointing out function modules is highly appreciated. Points will be rewarded. Thanks in advance.

Hi ,
Check the following function groups for file related operations.
GRAP - Frontend related.
SVRZ - System related.
SFTP - FTP related.
SFIL - Logical file name related.
As per my understanding, we are not using any function modules to read data from application server.
Best of luck.
Thanks

Rfc function module call error

Hi Abaper,
I'm doing upgrade from 4.7 to ecc 6.0 currently and encounter problem in one of the rfc function module that we used. I've tested the connection to destination using sm59 and the connection is successful.
As an information, in the rfc setting, the target system is not Unicode system.
When I test using se37 and put the rfc destination in my function module call, I always encountered system_error exception. There's no issue with this rfc call before in 4.7 system.
Please help me on this. Thank you.
Edited by: Abraham Bukit on Sep 3, 2008 2:36 AM

Hi,
I had the same issue in the past and solved it in the following way.
If the destination system is not Unicode please try to set the password for the communication user set in SM59 using only upper-case characters and taking into account that the password shouldn't be longer than 8 characters.
Hope this will help.

now my first question is what is the difference between function modules calling normally and in the above said way
and the second question is
under tables parameter i have four internal tables defined where as while calling the same function module using recive results i have three internal tables. is this correct?
i am asking this because i am getting an error message while using this funciton module
please do not give generic answers, all the helpful answers will get a def reward

Call function starting new task is used to make Asynchronus RFC Call. In this case your function module will be called in a NEW SESSION and it will exceute independently from the Main program which is calling the FM. Also, the main program will continue its own processing and it will not wait for the RFC FM to complete.
Its not mandatory to have all the TABLES parameters in the RETURN Perform (..Receive results from ...)

Need to track Function modules called when executing a transaction

Hi All,
Is there a way through which i can track function modules called, while executing a Transaction. Kindly provide pointers to it.
Thanks in advance.
Regards,
Navin.

Goto SE80 Transaction and use Program name for corresponding Transaction Use Find operation like Call Function .. then you will get list of FM ..
There is no other option .

Can a function module call another function module

Can a function module call another function module:-
within the same function group
(ii) within different function groups

Hi,
We can call function from another function. If there is a function which is like a calculator and all the operations are from different functions then we have to call the functions from the calculator function for different functions.
If all the function are from same function group, Then the data is globally available to all the functions with in the group.
Otherwise we have to declare the data definitions for each of the functions if they are in different function groups.
Yes it is possible to call a function module from another function module:-
within the same function group
(ii) within different function groups

Dynamic function module call

Hi,
I need to call few function modules dynamically.The exporting and importing parameters are also known only at run time.
Can somebody help me out in this regard,
Thanks and regards,
Archna

hi ,
Create Function module according to your requirment and call the same
such as
Create functi0n module   where you are passing PLant runtime   and get data related to Plant
write code in function according to requirment .
FUNCTION zrfc_test.
""Local interface:
*" IMPORTING
*"     VALUE(ZWERKS) TYPE MARC-WERKS OPTIONAL
*" EXPORTING
*"     VALUE(RETURN) LIKE BAPIRET2 STRUCTURE BAPIRET2
*" TABLES
*"      ZIT_DATA STRUCTURE MARC
IF zwerks IS NOT INITIAL.
    SELECT *
      FROM marc
      INTO CORRESPONDING FIELDS OF TABLE zit_data
     WHERE werks = zwerks .
ELSE.
    SELECT *
      FROM marc
      INTO CORRESPONDING FIELDS OF TABLE zit_data.
ENDIF.
IF sy-subrc = 0 .
    MESSAGE ' Selected ' TYPE 'I' .
ENDIF.
ENDFUNCTION.
Suppose at runtime you get Plant 7100
types : begin of w_marc .
         include structure marc .
types : end of w_marc .
data : it_data type standard table of w_marc with header line .
p_plant = 7100 .
Call to function module
CALL FUNCTION 'ZRFC_TEST'
EXPORTING
   ZWERKS         = 'p_plant
IMPORTING
RETURN         =
TABLES
    zit_data       = it_data .
You will get result in it_data .
Note : if you don't know how to create Function Module then search on SDN you will get lots of Forum .

Idoc - Error Status 51: Incorrect function module called up

Hi,
In the receiver system for the custom message type, I got this error.
Incorrect function module called up
Can any one pls help me to solve this one.
Regards,
Bala Raja

Hi Bala,
     Check the inbound function module attached to process code in receiving system. Generally in every inbound function module first check is coded for checking message type or for checking funciton module like below.In the receiving system go to WE20 and then select the partner and select inbound message type. in that double click on assigned process code.then you have to double click on displayed FM. In that fm check first few lines. You will find this error message.
LOOP AT IDOC_CONTRL.
    IF IDOC_CONTRL-IDOCTP(6) <> 'DESADV'.
      MESSAGE ID 'E0' TYPE 'E' NUMBER '029'

Calling a function module on another server

Dear all,
I have a function module on a test server which accesses a database table on it. I need to call that function module from a development server. Both servers are AS ABAP. I believe I need RFC, but how do I specify the test server address from the development server function call?
Thanks for your help,
Philon

You need to call the Function module as a RFC FM.
The function module needs to be set as such.
In its atributes, it needs to be Remote-enabled function module.
To call it, proceed as follows:
CALL FUNCTION <FUNCTION MODULE> ON <DESTINATION>.
<DESTINATION> needs to be a predefined RFC destination. (See transaction SM59)
CALL FUNCTION func DESTINATION dest parameter_list.
Effect
Synchronous call of a remote-enabled function module specified in func using the RFC interface. Use addition DESTINATION to specify the destination in dest. For func and dest, character-type data objects are expected. After terminating the remotely called function, the calling program is continued after CALL FUNCTION.
Note
If the content of dest is equal to the constant space, then the addition DESTINATION is ignored and a normal call CALL FUNCTION func is executed.

ABAP Dump due to RFC Function module call in another thread

Hi,
I am facing some problem since yesterday. In one of my executable program I am calling a RFC fm as below mentioned
REPORT ZREPORT.
CALL FUNCTION 'Z_XXXXXXXXX'
      STARTING NEW TASK L_NAME
      DESTINATION IN GROUP 'TASK'
      PERFORMING RETURN_INFO ON END OF TASK
      EXPORTING
        P_exp1       = l_emp
      TABLES
        R_VBELN      = r_it_vbeln
      EXCEPTIONS
        NO_DATA_TO_PROCESS = 1
        OTHERS             = 2.
wait until v_task = 1.
update ztable.
Due to some data inconsistence one of the SAP function
module which I am calling in my function module Z_XXXXXXXXX
is generating dump with message type X. Since there is data inconsistence it is generating dump that's OK.
But the problem i am getting is, report ZREPORT is generating dump at WAIT statement saying illegal statement even though I am calling that function module
Z_XXXXXXXXX as a separate new task.
Can somebody help me.
Thanks,
Amara.

hi, Amara
I agree with Rich said, and do a simulate test in my server, here is the analysis.
Assume we have a RFC, like this:
FUNCTION ZGZL_DUMPTEST.
*"*"Local interface:
*" EXPORTING
*"     VALUE(OUT) TYPE I
*" EXCEPTIONS
*"      CONVERT_FAIL
data:a type i.
a = 'A'.
ENDFUNCTION.
And call this RFC like you way:
REPORT ZGZL_DUMPTEST .
DATA:
SEMAPHORE(1) VALUE SPACE,
LC_OUT       TYPE I.
CALL FUNCTION 'ZGZL_DUMPTEST'
STARTING NEW TASK 'DUMP'
PERFORMING RETURN_INFO ON END OF TASK.
WAIT UNTIL SEMAPHORE = 'X'.
WRITE: 'OVER'.
FORM RETURN_INFO USING TASKNAME.
RECEIVE RESULTS FROM FUNCTION 'ZGZL_DUMPTEST'
          IMPORTING OUT = LC_OUT.
SEMAPHORE = 'X'.
ENDFORM.                    " RETURN_INFO
if we run the RFC in se37 directly, obviously it will occur a rumtime error CONVT_NO_NUMBER, and dump.
But if we run the above application to call the RFC, we will get a different runtime error CALL_FUNCTION_REMOTE_ERROR.
Error Analysis in ST22 like this:
An error occurred when executing a REMOTE FUNCTION CALL.
It was logged under the name "CONVT_NO_NUMBER"
on the called page.
I think that means the application receive the runtime error from RFC when call <b>RECEIVE RESULTS</b>.
In normal CALL FUNCTION, the external application will accept the rumetime error throw from FM, that's correct, because it let the caller can handle these runtime errors.
In you case, you said RFC run in a new task, yes, that's true, so you can call the RFC like this:
CALL FUNCTION 'ZGZL_DUMPTEST'
STARTING NEW TASK 'DUMP'
PERFORMING RETURN_INFO ON END OF TASK.
WAIT UNTIL SEMAPHORE = 'X'.
WRITE: 'OVER'.
FORM RETURN_INFO USING TASKNAME.
SEMAPHORE = 'X'.
ENDFORM.                    " RETURN_INFO
It will goes well, no dump. Why? because we don't use RECEIVE RESULT. RECEIVE RESULT will bring the result from FM, also bring the runtime error from FM.
So if you want to call the FM and receive the result, handle the runtime error in FM inside at first.
like this:
CATCH SYSTEM-EXCEPTIONS CONVT_NO_NUMBER = 1.
    a = 'A'.
ENDCATCH.
IF SY-SUBRC = 1.
    RAISE CONVERT_FAIL.
ENDIF.
And then you call FM like this:
CALL FUNCTION 'ZGZL_DUMPTEST'
STARTING NEW TASK 'DUMP'
PERFORMING RETURN_INFO ON END OF TASK.
WAIT UNTIL SEMAPHORE = 'X'.
WRITE: 'OVER'.
FORM RETURN_INFO USING TASKNAME.
RECEIVE RESULTS FROM FUNCTION 'ZGZL_DUMPTEST'
          IMPORTING OUT = LC_OUT
          EXCEPTIONS CONVERT_FAIL = 1.
SEMAPHORE = 'X'.
ENDFORM.                    " RETURN_INFO
That's will be ok for your scenario.
Hope my reply is useful.
thanks

Update sap table using a function module call by php code

Hello,

Marie, create a Blog please, about more details for dummies....
1) how to connect to sap system?
2) you run the php code where? in a webserver or where?
3) wich is the url for run the FM: ZZ_SET_DISTANCE
4) you placed some dlls files on the web server?
please is interesting this...

Getting values from a function module called in a WDA method

Friends,
I am trying to execute a function module from WDA.
I have created a service call for the function module. The function module takes values from the user, looks up the corresponding values of another field and returns the values in an internal table.
I am using the "Method Call in Used Controller" of WD Code wizard to call the function module.
When the event handler method containing the call to the function module is executed, nothing happens.
I am not sure how to pass values to the function module and to get the return values from the function module.
I am new to using function modules from WDA. Please help me out.
Thanks and Regards.

Rashmi,
Is the function module intended to collect input data from the UI and process it? - Yes
If yes, then the input (importing parameter) to the Function Module is a table of values (which should be ideally from the context mapped to the Table UI Element). - The importing parameter is a single value NOT a table and is mapped to the view context.
Now this table UI Element is bound to the view controller context , which in turn is mapped to the component controller context. And you are indeed being able to read the value of this internal table in the component controller method where the function module is being called by means of get_static_attributes_table (Is this right? - Yes, I am able to read the table of values that is passed from the component controller view to form view context by using get_static_attributes_table.
Or are you being able to read it in the event handler method of the view controller and not being able to read it in the component controller method) -
The function module takes a single value as import parameter and returns a table of values as return value.
It works fine when no importing parameter is being used and returns the table of values that is getting passed from component controller context to form view context when i am able to read it using get_static_attributes_table.
Now the question is: how to pass the import parameter value to the function module. I assumed since the importing parameter is a context node (like the return values are), i should set the value ( captured when the user enters the value in the form) to the importing parameter context attribute using set_attribute method. Since it is mapped to the component controller context, i assumed it will get passed and the method will take it as input parameter.
Let me know if my assumptions are correct regarding passing the import parameters and what is missing here.
Thanks and Regards.

Function module called within a loop seems to carry over global data

Hello all,
I am calling FM "RS_COVERPAGE_SELECTIONS" inside of a loop of all variants for a program and then writing the variant values to spool. If only one variant is entered on the selection screen, all the values are correct. If nothing is entered, some of the variant values are carried over from a previous variant. I am emptying the internal table returned by the FM every time before the FM executes.
Would some one be willing to run the following code for a program with many screen fields and many variants and tell me if they get the same behavior?
Thanks
Bruce

Hi
Try using the function module PRINT_SELECTIONS, within this FM, the FM RS_COVERPAGE_SELECTIONS is being called. So it will not copy the previous values.
Pass Mode as 'A' , report name and variant name, then it will display the same output.
Please try it

RFC remote function module call from XI

hi
I am trying to call a remote function module directly from XI which is not a bespoke module.
And i am getting the following error:
com.sap.aii.af.ra.ms.api.DeliveryException: error while processing message to remote system:com.sap.aii.af.rfc.core.client.RfcClientException: failed to parse BAPI response due to: com.sap.aii.af.rfc.util.bapi.BapiException: Parameter with name RETURN not found.
Please help me in this.
Thanks in advance.

Hi Naina,
Normally RFC are synchronous, they do have return parameter as export parameter.
If return parameter is missing then , you can create Wrapper RFC.
Wrapper RFC:
It is nothing but you just create BAPI in SE37 transaction with Return parameter as export parameter and make it remote enabled by clicking on Radio button.
Under source code, CALL BAPI which XI has to call.
Thats it!
I hope this helps.
Let me know if any help required.
