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.
regards.

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.

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.

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'.

RFC enabled function module using call transaction

Hi,
We have a scenario wherein we have a RFC enabled function module which inturn uses a call transaction to create a PM order & attaches the PM notification against it. Sometimes it so happens that the order does not get created for some reason or the other and there are no logs generated on the system to investigate. However we are capturing the messages produced via the BDCMSGCOLL. At present we are using the update parameter as 'L'.
In some scenarios it states that the notification is locked by the same notification and comes out without creating the order, in this process we are losing out on the order & the notification number which if successful would have got updated in the database.
I know this could be done via the BAPI, but there are innumerable steps within the BDC which can't be actually done using the BAPI and hence we could not use this procedure.
Is there any other way by which we can ensure that there's always a successful order creation, I mean without losing out on the order/notification number?. Would changing the update mode to 'S' help?. Since this process is time bound, it can't actually take more time then what its taking with the current logic.
Please let me know if you require further details on the same. Any help in this regard would be highly appreciated.
Regards,
Vidya

Sorry for an unclear replay.
In Simple terms; I have 2 scenarios;
Launch a new tab (IW38 tcode), on click of a button in SAP screen of custom transaction in NWBC.
Launch a new tab (IW38 tcode), on click of a button in a Non - SAP App opened (using URL) in NWBC.
For 1st case, i have used
CL_NWBC=>URL_CONSTRUCT
EXPORTING
     CANVAS_WDA__CLIENT_TYPE       = 'nwbc'
     CANVAS_TRANSACTION            = 'IW38'
RECEIVING
     URL                           = lv_URL.
CALL METHOD CL_NWBC=>URL_LAUNCH
   EXPORTING
     URL    = lv_url
But it gets open in NWBC HTML not in NWBC Desktop client.
I tried all the Parameters you have mentioned in your response to this post earlier, but nothing worked. the last one is CANVAS__WINDOW which actually hides the top area and few buttons but still it is a HTML version.
If i set the HTML_CLIENT = ABAP_FALSE, it launches a new window instead of the tab and asks for Login. If i login in can see the IW38 in NWBC desktop client. But the only problem is we have the restriction of single window/single login for users.
I am on NWBC PL12 and also updated the GUI 7.3 to PL8.
Simply the problem is URL_CONSTRUCT for any transaction is launching it in a new tab but in HTML Version.
For 2nd case,
It asks for the login details on click of a button on the 3rd party URL opened in NWBC. which means i am launching SAP from a 3rd party.
Is there any way to achieve the launch of new tab in this case instead of the new window ?
I hope its more clear now.
Regards,
Nik.

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 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.

How to call Custom RFC enabled Function Module in R/3 From XI

Hi Experts,
I want to call custom RFC enabled Function Module by sending some input parameters from XI.
How to do this
Thnx
RAMS

Hi RAMS,
1. Under the SWCV Go to the Imported Objects.
2. Right click on the RFC and click on the Import of SAP object.
3. Give the logon server name, system number the user name and pasword.
4. Select the RFC u want to import.
5. Execute the import and the RFC is imported under the SWCV.
Now u can use this Imported RFC in the scenarios of that SWCV.

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..

How to call a RFC-enabled function module

Hi All,
We have 2 systems; system 1 (client 420) and system 2 (client 600).
I just want to know that how can a RFC-enabled function module be called from one system (420) whereas the RFC-enabled functio nmodule exists in the other system (600).
Also, as per my understanding any RFC-enabled function module is a BAPI. Please confirm.
Please help.
Thanks & Regards,
Namrata

Hi,
RFC enabled FM can be called from anther system:
From 420 we can call RFC FM residing in 600, through RFC destination cretaed in SM59 tcode in 420 client.In sm59, maintain the entries of destination system i.e 600.and test the connection whether it is succesful or not/ through remote logon.
suppose in 420 client , in sm59 u have cretaed with destination DEST600 say.
In 420, u can code as below..
Call 'RSSDK_LOGSYS_REMOTE_CHECK' destination DEST600
exporting
I_QSYSTEMNAME =
tables
E_T_MSG =
there exist difference between BAPI/RFC.
BAPI always return messages / RFC doen't.
BAPI follows ceratin naiming convetions while defineing the parameter structures ( ex BAPI_..)
In bapi , no dialog screens can be called.
In bapi, statements liek COmmit work/Call Transaction/Submit...shouldn't exit.
Bapi's are implemented as FM's and are stored as methods in Business Object repository.
another Ex for RFC

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 Error While Invoking A Remote Function Module.

I am invoking A remote function module while invoking it get an exception when i see the error logs
com.sap.tc.webdynpro.modelimpl.dynamicrfc.WDDynamicRFCExecuteException: Screen output without connection to user. , error key: RFC_ERROR_SYSTEM_FAILURE at com.sap.tc.webdynpro.modelimpl.dynamicrfc.DynamicRFCModelClassExecutable.execute(DynamicRFCModelClassExecutable.java:101) at... [see details]
can anyone pls tell me what the error is..

Nilesh Taunk.

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!

Problem with String parameters while Calling RFC enabled Function Module

Hi all,
I execute BAPI(RFC enabled Function Module) from my WebDynpro Application and retrieve data from R/3.
To fetch the data I pass few String parameters to BAPI from my Dynpro Application.
Now the problem is that while making this call, the parameters are automatically converted to UpperCase. And I want those parameters in the original case at R/3.
I am not able to find out whether this conversion occurs at Dynpro side or R/3 Side.
Should i configure my BAPI(RFC enabled Function Module) or is there some option on the Dynpro Side to preserve the Case of the String?
Please help me.
Thanks,
Darshil

Hi Darshil,
I'm not sure whether you have experience with ABAP or you are a Java Programmer, but we cannot set that flag permanently.
Now, if you are saying that the domains are marked with the Lowercase attribute, then it means that the final table field will be capable of holding Case Sensitive data.
I have a hunch that the case-conversion is happenning at the Web-Dynpro side. Or, the application logic converts the string to UPPERCASE explicitly.
By the way, which BAPI are you talking about ?

Anand Mandalika.

RFC enabled function module which will be called from XI

Hi Abappers,
I have to send confirmation of the sales orders created by inbound Idocs ORDERS05 to XI. For this I have to use outbound Idoc ALEAUD01. But since I also need to send NETWR(from VBAK) and there is no field in this Idoc for that,
I have to develop an RFC enabled function module for which a RFC lookup will be performed from XI. This function module has to return NETWR values for sales orders. Can anyone please tell me how to go about with this function module.
Thanks in advance.

Hi Priyanka,
Add a parameter in tables tab of function module with reference to NETWR. It'll work.

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.
I think this was your requirement.
