Remote function module to wait untill the response came from webmethods

hi all.
here i have got a situation that the remote function module created in SAP-R/3 to wait untill the response came from webmethods :
i have created the remote function module by assigning one structure in tables(tab) and 3 parameters in changing tab just to collect the messages return from webmethods
so this rfc will be called by webmethods and pick the structure data and then it wll return 3 variables back to rfc.
here the rfc need to wait untill the response came from webmethods.
so can any body suggest me on what source code do i need to write in RFC

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.

Remote Function module to wait for the response.

Hi .
i just created the remote function module to call the webmethod by putting the parameters in tables (tab) for webmethods to pick the data from RFC and parameters in changing (tab) to collect the reponse from webmethods ,i just want to know if this is the right way of creating the RFC for webmethods and the RFC need to wait for certain time until it should get the response from webmethods.
can any body guide me in this on how i can make the rfc to wait untill it will get the response from webmethods.
waiting for your response.

Hi Jaswanth,
FM used to upload the data from the non sap system to the SAP sytem is the GUI_UPLOAD ans GUI_DOWLOAD is downloading the data from SAP to the presentation server .This file can be xls,tab or space deliminatior ettxt fiel.
I think this was your requirement.

Function Module required to convert the date coming from external system

Hi Friends,
I need a Function Module that would convert the incoming date from external sytem in format YYYYMMDD to the SAP system in DDMMYYYY. The External system data type for the date is Numberic. Please suggest any FM if you know.I found out many in SAP but didn't find for this requirement

Wait a minute. I am definetely missing something here. You want to convert from an external format YYYYMMDD to SAP's internal format? SAP's internal format is YYYYMMDD.
All you should have to do is move you external date directly to your internal date.
data: date1(8) type c value '20051225'. "Format YYYYMMDD
data: date2 type sy-datum. "Format (YYYYMMDD)
write: / date2.
When you write out date2 it will be in whatever format your user profile has.
If you want to force the date format independent of your user profile settings during the write statement:
write: / date2 DDMMYY.

Function module to find out the changed values from tables

What is the standard function module to find out the changed values (the old & new values) from tables in SAP ?

Hi Harish,
Please elaborate your requirement...
Please have a look on CDHDR AND CDPOS tables... it contains changed data... but all chages are not being tracked using it..
Try Below FMs as well..
For Header Level...
CALL FUNCTION 'CHANGEDOCUMENT_READ_HEADERS'
    EXPORTING
      date_of_change    = cdhdr-udate
      objectclass       = cdhdr-objectclas
      objectid          = cdhdr-objectid
      time_of_change    = cdhdr-utime
      username          = cdhdr-username
    TABLES
      i_cdhdr           = icdhdr
    EXCEPTIONS
      no_position_found = 1
      OTHERS            = 2.
For Item Level
CALL FUNCTION 'CHANGEDOCUMENT_READ_POSITIONS'
      EXPORTING
        changenumber      = icdhdr-changenr
      IMPORTING
        header            = cdhdr
      TABLES
        editpos           = icdshw
      EXCEPTIONS
        no_position_found = 1
        OTHERS            = 2.
Hope it will solve your problem..

Debuggin a Call to Remote Function Module

Hi
I have a scenario where i have a Remote Function Module in r3 which is being called synchronously by an external java application. The FM has a lot of input and output parameters and many tables. The output returned by the FM is not as expected.
Can anyone tell me how debug a Remote Function Module when a call has been made from an external application.
I am not able to get the test data sent by the external application . So when the external application gives a call to this Remote FM and if it is possibele to debug it would be great.
regards
Nilesh Taunk.

Hi Nilesh,
1) Login to SAP with the same ID with which you will calling the RFC function module from the outside system.
2) Goto transaction - se37/se38
3) Goto Utilities => Settings.
4) Select the ABAP Editor Tab.
5) Click on the Debugging tab.
6) Tick the Actv. button and give the user name with which you will be debugging the code. In this case the logged in user id.
7) Press Enter.
8) Now put an external break point inside the Function Module.
9) Load your external application (from where you want to debug the FM) once again.
The execution will stop in the FM.
Hope it helps..

REMOTE FUNCTION MODULES

hi all,
i want to know how to create remote function modules. how to give the import and export parameters. i want the link of how to create the function modules.
bye
suresh

Hi Suresh,
Goto transaction
SM37 -> Create your function module as Z_FUNCTION.
Assign a function group ( if function group is not there then create a function group as SE37 -> GOTO -> Function Group -> Create Function Group)
On attribute tab, you will see three radio buttons.
Select 'Remote enabled module'
Select :Import tab.
Enter i_MATNR
Type MATNR
Select : Export tab
Enter : e_mara
TYPE MARA
Select : Source Code
Enter :
SELECT SINGLE * FROM MARA INTO e_mara FOR MATNR = i_MATNR.
Save your module.
Activate it.
Test using F8.
You can call this function in your program as
CALL FUNCTION 'Z_FUNCTION' DESTINATION destination_name.
Hope this will help.
Please award few points if it resolves your issue.
Thanks and Warm Regards.

Regarding the Remote Function Module

hi,
Can any body can provide the brief information regarding the Remote Function Module.
1)How to create the remote function module
2)how it differ from the normal function module
3)any special features about this.
Thanks in advance

Hi
RFC (Remote Function Call) is similar to the general SAP fun module: except that in the attributes you click the radio button: RFC enabled;
and you will be passing an Import parameter DESTINATION to it.
Other code and usage will be similar to any fun module;
Have a look at any fun module in SE37 to understand better about the different components of Fun modules;
Refer this link:
http://help.sap.com/saphelp_nw04/helpdata/en/22/042518488911d189490000e829fbbd/frameset.htm

Function Modules;
Check this matter.
Function Modules are Global ABAP programs created by SAP for reusable purpose.they have IMPORT,EXPORT and TABLE parameters, and EXCEPTIONS to through when error occurs.
You can create them from TCode SE37.
Go through the following doc:
Function modules are cross-program, reusable procedures that are organized into function groups, and whose functions are implemented between the statements FUNCTION and ENDFUNCTION. Function modules and their interfaces are created in the Function Builder.
Function Module Interfaces
The parameter interface of a function module is defined in the Function Builder. It includes the definition of interface parameters and the specification of exceptions that can be triggered by a function module. The Function Builder automatically generates comment lines below the FUNCTION statement in the source code of the function module, which represent the interface of the function module with the following syntax:
Syntax
... [IMPORTING parameters]
[EXPORTING parameters]
[CHANGING parameters]
[TABLES table_parameters]
[{RAISING|EXCEPTIONS} exc1 exc2 ...]
The syntax and semantics of IMPORTING, EXPORTING, CHANGING, RAISING, and EXCEPTIONS mainly correspond to the definition of method interfaces with [CLASS-]METHODS. The additional option of defining table parameters using TABLES is obsolete.
Interface parameters
The interface parameters are defined on the relevant tab pages in the Function Builder.
IMPORTING parameters are input parameters. When the function module is called, a suitable actual parameter must be specified for every non-optional input parameter. The content of the actual parameter is passed to the input parameter when the call is made. The content of an input parameter for which 'pass by reference' is defined cannot be changed in the function module.
EXPORTING parameters are output parameters. When the function module is called, a suitable actual parameter can be specified for every output parameter. The content of an output parameter that is defined for 'pass by value' is transferred to the actual parameter if the function module is completed without errors. An output parameter that is defined for pass by reference is not initialized when the function module is called.
CHANGING parameters are input and output parameters. When the function module is called, a suitable actual parameter must be specified for every non-optional input or output parameter. When the function module is called, the content of the actual parameter is passed to the input/output parameter, and when the function module is completed, the content of the input/output parameter is passed to the actual parameter.
TABLES parameters are table parameters. Table parameters are obsolete CHANGING parameters that are typed as standard tables with a header line. If an internal table without a header line or a table body is passed as an actual parameter to a formal parameter of this type, an empty local header line is generated in the function module. If an internal table with a header line is used as an actual parameter, both the table body and the header line are passed to the function module. Pass by value is not possible in formal parameters defined using TABLES. Formal parameters defined with TABLES can be replaced by formal parameters defined with CHANGING. A local work area can be created for the internal table in the function module by using the addition LIKE LINE OF itab of the DATA statement.
Exceptions
The exception of a function module are defined on the Exceptions tab page in the Function Builder. Here you can select exception classes to define whether class-based exceptions are declared or non-class-based exception are defined. Class-based exceptions are represented in the above syntax by RAISING, and non-class-based exceptions are represented by EXCEPTIONS.
The addition RAISING is used to declare class-based exceptions that can be propagated from the function module to the caller. Exceptions in the categories CX_STATIC_CHECK and CX_DYNAMIC_CHECK must be explicitly declared, otherwise a propagation can lead to an interface violation. A violation of the interface leads to the treatable exception CX_SY_NO_HANDLER. Exceptions of the category CX_NO_CHECK are implicitly always declared. The declaration of exceptions of the category CX_STATIC_CHECK is statically checked in the syntax check. For exceptions of the category CX_DYNAMIC_CHECK, the check is not performed until runtime. In a function module in which class-based exceptions are declared with the RAISING addition, the statement CATCH SYSTEM-EXCEPTIONS cannot be used. Instead, the relevant treatable exceptions should be handled in a TRY control structure.
The addition EXCEPTIONS is used to define a list of non-class-based exceptions that can be triggered in the function module using the statements RAISE or MESSAGE RAISING. Exceptions defined in this way - as with formal parameters - are bound to the function module and cannot be propagated. If an exception of this type is triggered in a function module, and no return value has been assigned to it with the homonymous addition EXCEPTIONS of the CALL FUNCTION statement when the call was made, this leads to a runtime error.
Note
For new developments after release 6.10, SAP recommends that you work with class-based exceptions that are independent of the function module.
RFC is a technology which is used to access a functions (Modules) from
the remote systems.
If a function module is set as remote enabled which can be access from
the remote system via RFC.Eg: U can access the Remote enabled function modules in ur VB,Webdynpro,Java,Visual composer program.
A function module can be set as remote enabled by SE37->Go to ur FM->click the option Button "remote enabled".
But Normal function modules can not accessd from the remote system.
Good Example for RFC enabled function module is : BAPI(Business Application Programming Interface)
Note: All BAPIs are Remote enabled but not all remote enabled function modules are BAPI.
CALLING A FUNCTION MODULE:
1)In U ABAP Editor --> Click "Patter" ---> Selection Option Button "Call Function"
--> Write the Corresponding FM name --> Hit Enter
2)The appropriate import ,export Parameters will be displayed in ur editor
3)Pass the Values Here.

Error in calling the Remote Function Module

Hi all,
I am trying to call the Remote function Module which is in CRM from ECC .
But we are not able to detect the function module as it is showing the error as Function Module not found.
Can anybody help us in calling the Remote Function Module .
Regards,
Madhavi

Please check the foll 2 things :
RFC radio button clicked in se37 for that FM
RFC connection established with the remote server in SM59
Thanks

What is the exact syntax for calling remote function module.

Hi to all
1.....what is the exact syntax for calling remote function module.?
Thanks and regards,
k.swaminath reddy

hi
good
Lets do simple example where you will first create a RFC in one server (say A) and create normal program in othere server (say B). Finally you will call the RFC in A from B.
Do the following steps for creating RFC in server A.
1. log on to server A
2. go to se37
3. Edit -> function groups-> create function group and give the function group name (say ZGRP).
4. create a FM ( say Z_TEST_RFC) in se37 providing the function group which is created just now.
5. go to attribute tab -> choose remote-enabled module from processing type.
so that your FM will become RFC.
6. provide the import parameter in import tab.
we will provide only two import parameters.
- parameter name : P_NUM1, typing: TYPE, associated type : I & check the pass value (all the parameters of RFC must pass by value).
- parameter name : P_NUM2, typing: TYPE, associated type : I & check the pass value
7. provide the export parameter in export tab.
parameter name : P_SUM, typing: TYPE, associated type : I & check the pass value
8. write the given simple code in source code tab.
FUNCTION Z_TEST_RFC.
P_TOT = P_NUM1 + P_NUM2.
ENDFUNCTION.
Do the following steps for creating ABAP program which will call the RFC in server B.
1. se38 - > creat a program.
2. write the given simple code.
data tot type i.
call function 'Z_TEST_RFC' destination 'XXXXXX'
exporting
p_num1 = 10
p_num2 = 15
importing
p_tot = tot.
write tot.
please note that XXXXXX is RFC connection which is avialable in sm59 transaction in server A.
-go to sm59 - > abap connection (list of RFC connection configurations are avialable). choose server B connection and replace it of XXXXXX in the code.
finally you can execute the normal abap program that will call the RFC and display the result.
reward point if helpful.
thanks

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.

Wait until the session has been processed

Hi folks,
I have a report in which I create and trigger an SM35 session. I use RSBDCSUB report to do the same.
Now, is there anyway to wait until the session has been processed? I mean, I need to do a few things in the report only after the session has been processed.
Thanks

Hi,
You could try checking the job status (table TBTCO) inside a DO or WHILE loop. To pause up to 5 seconds between your lookup on TBTCO, you can call function module 'RZL_SLEEP'.
If checking TBTCO does not work out for you, you can try the same loop logic with a call to function module 'ENQUEUE_BDC_QID' instead of looking up the job status. If the enqueue has been released then the job has finished.

Hi Nilesh Taunk,
You can go through the following steps
-o JCO Exceptions 1. http://help.sap.com/saphelp_nw04s/helpdata/en/f6/daea401675752ae10000000a155106/frameset.htm
-o JCO Exceptions 2. http://help.sap.com/saphelp_nw04/helpdata/en/f6/e002416225f023e10000000a155106/frameset.htm
-o Restart of the J2EE instance and try re-importing the RFC model. Sometimes it helps.
-o Logon into WebDynpro Content Administrator as a J2EE Admin and check if the JCO Connections and User /pwd of your application is correct. You can ping or test your JCO connections. if something is wrong, enter the values again for JCO n retest them.
-o Try undeploying or removing the complete application and redeploy it.
Tu undeploy please go to
Go to Visual Admin -> Server -> Services -> Deploy ->

Under Runtime Tab
select the server, open the tree , you would find the webdypro list there.
Now select an application, first stop it, remove it and redeploy if necessary.
Let us know if you could solve the problem or not, gud luck!

How to debug a remote function module in calling system? Help!

Hi Experts,
 I have a ABAP report (in System A) from where I am calling a remote function module which exists in a different system B.
ABAP Program(System A)<----calls--
RFC(System B)
Can I debug the RFC funnction module in system A using ABAP debugger? In other words if i put a breakpoint on the "call function" statement then in debug mode I want to see that the control is going to system B and I should be able to process the FM code line by line. Is this possible?
Is there any special transaction or settings?
Is there any alternative?
Please help
Thanks
Gopal

hello,
Try this method.
first check whether RFC connection is working b/w 2 systems.
if connection is working, then do like this.
In System B , put endless loop in FM before some main select statement.
like
DATA : v_a TYPE c VALUE space
DO .
 IF v_a = 'X'.
 EXIT.
 ENDIF.
ENDDO.
the above code will be endleep loop.
In system A, when cursor goes to CALL FUNCTION DESTINATION 'XXXXX'.
u shud be logged in system B. the moment control comes to system B.goto tcode SM50 . check ur username . choose that particular checkbox then in menu bar --> program/session --> Program --> Debugging.
i hope it will help u.
try & let us know.
Thanks,

Remote function module is not compilable, normal function is not

Hi,
i have a function module with processing type "normal function", which is compilable and working well. I'm using the type definition ABAP_COMPNAME.
If i change the function module to "remote-enabled", i'm getting a compiler error that ABAP_COMPNAME is unknown.
Can someone explain why this is happening? For what reason ABAP_COMPNAME is no longer available when i'm chnaging the FM to remote enabled?
PS Please dont give any hints how to change my function module, that is NOT the question. I just want to understand the mechanism behind.

It is clearly mentioned in SAP Help that we cannot use types from type-pool
in RFC function modules.
Associated Type of an Interface Parameter
ABAP associated type for an interface parameter. The associated type must be a
global Dictionary type or exist in a type pool. In the latter case, the type pool must
be declared in the function group.
Note that you cannot use types from type pools for RFC-enabled function modules.
When assigning a type using the LIKE typ method, you cannot use types from
type pools either.
Additionally you can use the internal ABAP types C, I, N, X, P, D, T, F, and the
TABLE type - to an extent in generic form.
You can find further information about this in the Function Builder manual and in the
ABAP online documentation under the keyword "Types".

Remote Function Module problem

Hi Experts,
I have written a Se38 progarm to execute a remote function module, so as to send some data out of the system. The receiving system is an XI system. Pls see below the code and the load at the XI end, I donno why and what mistake am I doing in the se38 program part, as a result of which, only part of the data is getting send to XI.
REPORT ZRFC_ADAPTER.
Data: it_final1 type standard table of zrfc_str with header line .
it_final1-NAME = 'ARNAB'.
it_final1-ADDRESS = 'ADDRESS'.
it_final1-EMAIL = 'EMAIL'.
it_final1-ID = 'ID'.
CALL FUNCTION 'ZRFC_XI'
IN BACKGROUND TASK DESTINATION
'R32XIRFC'
EXPORTING
username = sy-uname
tables
it_final = it_final1 .
break-point.
COMMIT WORK.
Clear it_final1.
I have seen in debugging mode, after removing the "
IN BACKGROUND TASK DESTINATION
'R32XIRFC'", that the internal table " it_final1 " is working fine......
The structure used in remote Function Module is
IT_FINAL LIKE ZRFC_STR -- in tables parameter. and the structure of ZRFC_STR is as follows!
NAME ZNAME CHAR 14
ADDRESS ZADDRESS CHAR 40
TELEPHONE ZTEL CHAR 20
EMAIL ZEMAIL CHAR 40
ID ZID CHAR 10
Note that , apart from a COMMIT WORK statement, there is no other coding done in the SOURCE CODE part of the remote Function Module.
The load in XI is showing as
<?xml version="1.0" encoding="UTF-8" ?>
<rfc:ZRFC_XI xmlns:rfc="urn:sap-com:document:sap:rfc:functions">
<USERNAME>RETAILDEV</USERNAME>
<IT_FINAL>
<item>
<NAME>ARNAB</NAME>
<ADDRESS>EMAIL</ADDRESS>
<EMAIL />
<ID />
</item>
</IT_FINAL>
</rfc:ZRFC_XI>
Note that EMAIL is actually a content of field EMAIL and not ADDRESS. But I donno why, it is behaving like this,,
Pls note, this RFC has been imported completely in integration repository of XI, so we dont have to worry about any settings change or activities, left pending in XI.
I am very sure, something is missing in the se38 code, pls suggest!!
Regards,
Arnab .

Hi Arnab,
I am having really doubt that there is problem in field mapping.
COuld you please check the following.
In the FM structure contains 5 fields as follows,
NAME ZNAME CHAR 14
ADDRESS ZADDRESS CHAR 40
TELEPHONE ZTEL CHAR 20
EMAIL ZEMAIL CHAR 40
ID ZID CHAR 10
In the Internal Table it has got 4 fields. Check the Mapping properly
and data on each field.
t_final1-NAME = 'ARNAB'.
it_final1-ADDRESS = 'ADDRESS'.
it_final1-EMAIL = 'EMAIL'.
it_final1-ID = 'ID'.
Thanks & Regards,
