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..

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,

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

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,

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.

To call webmethods using RFC(Remote Function Module)

Hi Sap Group.
i have got a situation on how to call the webmethods using Remote Function Module ,i know that there should be rfc destination created in sm59 already,so can i use the same existing rfc destination which was used to call webmethods with another scenario in my interface.
can anybody help me in this.

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

Problem while calling an RFC Function Module in Background

Hello,
I have created a RFC function module for reading data from an external DB system. The FM calls an external RFC program (coded in C++ using RFC SDK), which delivers the required data. This external program is maintainged as an TCP RFC Connection in SM59.
Further I have created a report, that calls the RFC function module to get the data from the external RFC programm.
My problem is, when I call the report in foreground, everything works OK, the RFC connection works and data can be read from the external program.
However, when I schedule the report to run in background as a job, the report is stating in the protocoll that there was a problem calling the defined RFC connection (although the connection is working properly at that time).
More funny is, this particular problem with running in background occurs only in the productive system, in test and development system the report works correctly also while running as a job in background.
Can you suggest the solution to this problem? Could it be something with authorisations or server settings?
I will be on holiday for the next 6 weeks, so take your time to answer .
Regards,
Dusan.

Please read the forum rules about u r g e n t ...

This is an external RFC server program, not a remote enabled ABAP RFC function module as the others seem to be assuming, right?
Is it possible that your DEV and QAS systems only have one application server, but the PROD has many and dedicated one(s) for processing low priority background jobs?
It might be that the target server of your TCP connection is not this BTC instance, and your RFC server is returning the data "locally" - so, into nirvana...
Just guessing, but might be worth checking.

Julius

Calling a RFC Function Module

Hello Guys,
I have a question regarding calling a RFC function module.
In BW - BI 7.0 I call a RFC function module:
(The ABAP program in BW-BI 7.0 is below)
CALL FUNCTION ''ZTESTFUNCTIONMODULE' " Function module in ECC
     DESTINATION 'DECCLNT110' " ECC system
    TABLES
      it_gl_item   = it_gl
      it_errlog_gl = it_errlog_gl.
The 'ZTESTFUNCTIONMODULE'   is RFC enabled in the ECC system.
The purpose is we retarct the data from BW to ECC.
When I run the function module it always asks for the user id and password.
The SAP logon screen appears and it asks for the user id and password.
The destination is maintained in the SM59 transaction and also the user is maintained there. I think it should login automatically into remote system and return the tables. is it correct. How to skip the logon screen.
Do I have to pass the user id and password in the function module. I think it should take the user id from the SM59 destination. Is it correct.
Please advise. As always thanks for your help guys.

Hi Senthil,
I think you answered your query in your question itself
The user ID and password need to be maintained in RFC destination in SM59.
Go to SM59 and then click on test connection..if it does not ask for ID and passwoed that means correct ID and password is maintained in SM59 otherwise maintain it.

CALL_FUNCTION_REMOTE_ERROR when calling a remote function call through PI

Hello. Thanks in advance for your perspective on this.
We are developing an interface that runs in an R/3 system and is suppossed to perform a lookup in another R/3 system via a PI 7.0 system.
Here's what we are trying to do, let's call these systems "A", "B", "C" respectively.
R/3 -> PI   -> R/3
The R/3 system (A) executes code, which calls this function module like this:
      CALL FUNCTION 'Z_CHK_MAT' DESTINATION 'XI_RFCADAPTER'
        EXPORTING
          iv_region           = lv_region
          iv_matnr            = ls_matnr-matnr
        IMPORTING
          ev_flg_is_purchased = e_flg_is_purchased.
This code, is set via the "DESTINATION" parameter to use the RFC destination 'XI_RFCADAPTER'. This destination, points to the PI (B) system above.
Anyhow, we're getting a short dump in the R/3 (A) system, which is like this:
CALL_FUNCTION_REMOTE_ERROR
"JCO.Server could not find server function 'Z_CHK_MAT'"
From my analysis, I believe this is because the remote function module Z_CHK_MAT does not exist, in the PI (B) system.
Our developer, believes this should just "pass through" the PI (B) system, and call the function module in the R/3 (C) system.
Any insight on this? In this scenario, does this Function Module need to exist in the PI abap side? Can you give perspective / guidance on this?
Thanks a lot
Steve

No need to exist in PI ABAP side.
Just make sure that:
1. as Michal said, you import it in Integration Repository (and use it in your configurations);
2. the RFC Destination type that points to XI is of type T, not 3;
3. both the RFC Destination & the Sender RFC Adapter (and only them) are using the same Program Id.
Regards,
Henrique.

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 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,

Invoking a Remote function module for every 5days

Hi Experts,
How to invoke a remote function module in R/3 from XI for every 5days?
After invoking tht i need to post data to a FTP server! Could any one tell me how to achive this
Thnx
RAMS

Hi Ram,
             If your scenario is R3 -- > XI -- > FILE .
My suggestion is to go for ABAP Client proxies. It is fast and we can move huge data .
             1. Generate abap proxy from Outbound interface from R3system .
              2. Write ABAP report , call RFC , fill TABLE structure of abap and send to XI ( IS) . then according to the Receiver determination . It will create flate file .
            3. Schedule report once in 5 days .
                 Please refer how to work with abap client proxy   and steps to activae
How do you activate ABAP Proxies?

Export and Import Strings To/From Remote Function Modules

Hi,
I am building a Web Application in which the user can enter very large string (unlimited) and we want to store that value in the backend. So i need to create Remote function module which can take large strings, store it in backend and when queired export the strings to the calling web application.
The Remote function module is allowing me to create "Import" and "Export" parameter with type String....but it is not allowing the String type "Table" parameter. I am kind of stuck now as i want to import and export multiple records of type String.
Can anyone suggest an altenative?
Regards,
Kumar.

Hi,
To have a table parameter with string type fields, Goto SE11 and under data types, create a structure with the required fields of type string.
Then u can use this structure to refer to the table parameter and declare it as
p_tab like ZSTRUCTURE in the tables tab.

Vik

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.
regards.

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.
