Hi all,
I am having one question, How to invoke RFC function module from XI interface.
Please reply me as soon as possible.
Thanks in advance,

Hi,
To call the RFC in mapping u need to create the RFC lookups...check these links.
How we have to create the lookups?
Check this weblogs with some screenshots on how to achieve this:

How to create RFC function module and how to call this function module

Hi,
i want to know step for creating RFC function module and then How to use this function module from some other sap system.
Thnaks,
jigar

Jigar,
To implement a remote function module in ABAP, perform the following steps:
Register the module as remotely callable in the RFC server system.
In the function module Administration screen (transaction code SE37), set the field Can be called via REMOTE CALL. Registering a module as remote causes an RFC stub to be generated for it.
Write the code for the function module.
Create the destinations.....................
Displaying, Maintaining and Testing Destinations
To display, create or modify destinations, choose Tools ® Administration ® Administration ® Network ® RFC destinations or enter transaction code SM59.
Remote Destinations are stored in table RFCDES. The RFCDES table describes logical destinations for remote function calls.
It is not possible to maintain the RFCDES table directly.
You can also access logical destinations via the Implementation Guide (IMG) by choosing Tools ® AcceleratedSAP ® Customizing ® Execute Project ® SAP Reference IMG.
In the Implementation Guide, expand the following hierarchy structure:
Basis
Application Link Enabling (ALE)
Sending and Receiving Systems
Systems in Network
Define Target Systems for RFC Calls
Displaying Destinations
The initial screen for this transaction displays a tree:
Different connection types (i.e. partner systems or programs) are possible. For further information, see Types of Destinations.
To display all information for a given destination, double-click it, or place the cursor on it and press F2 .
To search for a destination, press the Find button and specify your selection. You get a list of all entries matching your selection. Place the cursor on the one you want, and press F2 or simply double-click the destination. All information for the given entry appears.
Creating Destinations
On the destinations overview screen (transaction code SM59), the connection types and all existing destinations are displayed in a tree structure.
All available connection types are explained in Types of Destinations.
To create a new RFC destination, press the Create button. A new screen is displayed with empty fields for you to fill in.
If you want to create a new destination
As you create a remote destination, you can specify a particular application server or a group of servers for a balanced distribution of system load.
For details of the destination parameters, see Entering Destination Parameters.
Changing Existing Destinations
On the destinations overview screen (transaction code SM59), the connection types and all existing destinations are displayed in a tree structure.
You can display all information for a given destination by double-clicking it or pressing F2 on it.
To change an existing destination, double-click it, or place the cursor on it and press the Change button.
For details of the destination parameters, see Entering Destination Parameters.
Testing Destinations
To test a destination, choose the appropriate function from the Test menu.
Connection (also available via the Test connection pushbutton)
Authorization (checks logon data)
Local network (provides a list of application servers)
You can use the CALL FUNCTION statement to call remote functions, just as you would call local function modules. However, you must include an additional DESTINATION clause to define where the function should run:
CALL FUNCTION RemoteFunction
DESTINATION Dest
EXPORTING
f1 =...
f2 =...
IMPORTING
f3 =...
TABLES
t1 =...
EXCEPTIONS......
The field Dest can be either a literal or a variable: its value is a logical destination (for example, "hw1071_53") known to the local SAP System. Logical destinations are defined in the RFCDES table (or the TRFCD table in R/2 Systems) via transaction sm59 or the following menu path: Tools ® Administration, Administration ® Network ® RFC destinations. You can also access logical destinations via the Implementation Guide (IMG) by choosing Tools ® Customizing ® Enterprise IMG. In the Implementation Guide, you can then choose Cross-application components ® ALE ® Communication ® Define RFC destination.
The remote function call concept, for example, allows you to access a function module in an R/2 System from an ABAP program in an R/3 System. If you want to read a customer record from your R/2 Systems database, create a remotely callable function module in the R/2 environment which retrieves customer records. Call this function from your R/3 System using a remote function call and listing the destination for the target R/2 System:

How to trigger RFC Func Module from XI.

Hi Everyone,
I am trying to implement a scenario where in the data is passed from
RFC (async) <--> (async) BPM (Sync)<--> (Sync) SOAP
I trigger the initial RFC function module in the background by running a report in R/3 to send data async to BPM.
But how do I trigger the receiving RFC (Async) in R/3 from XI to post the data sent by synchronous SOAP service.
Regards,
Ashish

Hi,
1. You can make the RFC as Sync so that you need to worry.
2. In BPM 1st step will be receive that is RFC Async, 2dn step is Send to SOAP Sync and what you can do is...
Get the SOAP response and have once more Send step in BPM and trigger that RFC you watnted to.
Thanks,
Prakash

How to call a function module from a transformation

Hi,
Could somebody please let me know how I can call an abap function module from a transformation (abap xslt program). I know how to call the class methods from transformation, but how do i call a function module..?
Thanks,
Shashi.
Edited by: Shashi Kanth Kasam on Apr 8, 2010 12:45 PM

Ya. I can do that. But I don't want to use a class and a method to call that function module. Want to directly call function module from transformation. Is that possible..?
Thanks,
Shashi

Problem with RFC function module from R/3 to CRM

Hi, i have a RFC function module created in R/3, this is the code:
function Z_CRM_PRODUCTO_INTERLOCUTOR.
""Interfase local
*" IMPORTING
*"     VALUE(GV_VKORG) TYPE VKORG
*"     VALUE(GV_VTWEG) TYPE VTWEG
*"     VALUE(GV_MATNR) TYPE MATNR
*"     VALUE(GV_KUNNR) TYPE KUNNR_V
*" EXPORTING
*"     VALUE(GV_KDMAT) TYPE MATNR_KU
*"     VALUE(GV_POSTX) TYPE KDPTX
*" EXCEPTIONS
*"      NOT_FOUND
UNPACK GV_MATNR TO GV_MATNR.
UNPACK GV_KUNNR TO GV_KUNNR.
select single KDMAT POSTX
          into (GV_KDMAT, GV_POSTX) from KNMT
          where   VKORG = GV_VKORG
                  and VTWEG = GV_VTWEG
                  and KUNNR = GV_KUNNR
                  and MATNR = GV_MATNR.
IF sy-subrc <> 0.
    RAISE NOT_FOUND.
ENDIF.
endfunction.
When i call this function from CRM, i do it like this:
CALL FUNCTION 'Z_CRM_PRODUCTO_INTERLOCUTOR'
DESTINATION LV_RFCDEST
EXPORTING
    GV_VKORG = lv_vkorg
    GV_VTWEG = ORGMAN_H-DIS_CHANNEL
    GV_MATNR = ORDERADM_I_WRK-ORDERED_PROD
    GV_KUNNR = WA_DATOS_PER-N_PAGADOR
IMPORTING
    GV_POSTX = IT_POS_LINE-DESCRIPCION
    GV_KDMAT = IT_POS_LINE-material
EXCEPTIONS
    not_found = 1.
where:
it_pos_line-descripcion type string
it_pos_line-material type string.
Well, my problem is that when debugging, in R/3 the 2 return values have the correct value, but when they are passed to CRM they have only one position.
As i've been told, it was working ok, but it's being wrong since we made a ¿conversion to unicode?. Maybe I should change the type of return ???
Thanks in advance !!!

Hello Maria,
Make sure you define your parameters in CRM exactly the same way as in R3, do not use type string here.
So:
it_pos_line-descripcion type C char 40,
it_pos_line-material type C length 35.
Kind regards,
John.

Debugging RFC function module from ECC to CRM

Hi All,
My requirement is to debug an RFC function module present in CRM(7.0) system from ECC(6.0) system. A report program in ECC will call CRM custom FM. I found many posts in SDN with the same issue and tried to implement suggestions provided there. But I couldn't succeed. The approach I followed is:
I logged in to ECC report program and kept an external breakpoint just before the function module call.
I logged in to CRM system, opened the function module and kept an external breakpoint there.
In both the systems I provided the dialogue userid( id through which I log in to SAPGUI) in the system->settings->debugging option.
In CRM I activated the external break point in transaction SRDEBUG.
Now when I execute the report program in ECC, control stops at the breakpoint. If I press F5 at the function call, control is not going to the external break point set in the CRM FM. I am getting output of FM directly.
I tried with different settings like turning on the check box for IP matching and session breakpoint active immediate, switching to classic debugger etc. I also tried to provide the RFC user id instead of dialogue user but system throws exception saying only dialogue userids are allowed. I found that by inserting an infinite loop statement, control goes inside the RFC CRM FM but I prefer not to change the code.
Please let me know if I missed anything.
Thanks and Regards,
Naren

Hi,
Debug RFC calls
When an RFC function module is called it is usually not possible to debug the call, using the below techniques we can achieve the same. For this example we are calling an RFC enabled FM in ECC system from CRM system.
Scenario 1: Calling a custom RFC FM
STEP 1: Add an infinite loop in the remote custom Function Module (adding a u201CDO. ENDDO.u201D statement at the start of the FM would be enough).
STEP 2: Execute your program in the CRM system. The execution stops at the RFC call, because of the infinite loop.
STEP 3: Now login to the ECC system and go to transaction SM51 select the process which is executing the RFC and navigate to the menu: u201CProgram/Session->Program->Debuggingu201D this triggers the debugger session in a separate window.
Scenario 2: Calling a Standard RFC FM
When we are debugging a standard program we cannot add the infinite loop, hence we cannot go to SM51 and debug the work process. The RFC destination for the ECC system has a User specified, the RFC function module gets executed using this users credentials. Usually the basis team set up the RFC user as non Dialog user, this does not allow debugging. Contact your Basis team and get this changed to a dialog user enabling you to debug RFC function calls via the normal debugger.
Note: User name configured in the RFC destination (transaction SM59)
Note: User type for the RFC User (transaction SU01D)
Hope this will be helpful..

Calling RFC Function module from JAVA

Hi All,
We have created a RFC Function Module for Billing Plan tab in Sales order (BDC). The function Module contains BDC. When we are running the same function module in SAP it is working fine. But when the FM is called in Java , it is allowing only maximum of 5 entries , when we trying to insert at 6th position in billing plan tab, we are getting an error.
Can any one help on this.
Points will be rewarded for helpful answers.
Thanks & Regards,
Kiran I

I think the problem is because of the number of lines displayed on the screen in the BDC session in the Billing Plan.
You might have to add the page down logic to your BDC program.

How to call Z-Function module from BAPI_IDOC_INPUT1.

Hi All,
Process code is :BAPI and standard function module is BAPI_IDOC_INPUT1.
I am coding all the logic for the INBOUND IDOC in the Z-Function module ZIDOC_INPUT_ZGOODSMOVEMENTOIL.
My requirement is:
Process code fires the inbound function module BAPI_IDOC_INPUT1, this in turn call the function module ZIDOC_INPUT_ZGOODSMOVEMENTOIL.
How can i call ZIDOC_INPUT_ZGOODSMOVEMENTOIL from BAPI_IDOC_INPUT1 to process the idoc.
Thanks in Advance.
Regards,
Umesh

Hi Krush,
Thanks for your reply,
Now i can trigger the idoc.
I have one more problem that if i want to add another z-segment to the attached idoc type its not allowing me its saying that it is already generated and cannot be changed.
if i am generating the BDBG transaction its not asking for specific segment and it automatically takes the segment and generates the function module.
How i can add an additinal z-segment to the idoc type and it generate through BDBG transaction to include in inbound function module?
Thanks in Advance.
Regards,
Umesh

How to debug Function Modules from ISA!!!

Hi Gurus,
How to debug the function modules from ISA.
For Ex:If i am in shopping cart or product catalog,e.t.c..i need to know which FM is calling from backend, how to debug the FMs/Bapis related to that from ISA side.
direct me to all the possible ways.
Regards,
Anil.

Hello Anil,
There are a few things you need to look at when trying to debug .
1. The function module needed ( you can do a trace to see which one is called.)
2. The user that is been user With statefull and stateless connection the FM can be called by either the JCO user or the internet user. This will need to be considered when setting your external break point.
3. The server been used, You will need to check the XCM to see which server is been used ie are you using a group connect of a specific server , You need to make sure that you are setting the breakpoint on the server that is specified in the XCM.
Have a look at note [871907|https://service.sap.com/sap/support/notes/871907] the attachment to the note may help you a lot. .
Hope this helps.
Regards
Mark

Hi friends,
Please guide me how can I send data from SAP -> Dotnet Applcation using Dotnet Connector through RFC function module from SAP side. In my scenerio, I Run Z transaction to executte RFC function module which create some data to pass to dotnet connector.
Regards,
Rajesh Kumar

Hi,
You can make use of Dotnet connector to read the content of SAP RFC .. (eaiest of all)
The RFC can be executed using connector , and can read the data simultaneously.. u need to code in dotnet for this..
else create a webservice and read it from dot net ..

I need to create RFC function module which creates the IDOC

Hi-
Any idea how to create RFC function module which creates the outbound IDOC. If you have any sample code please forward to me.
Thanks,
Sony

My Problem is
Whenever they create Invoice using T-code's like FV65(Parked Document), automatically should create IDOC's...
I have used message type FIDCC1 but this message type is usefull only for Posting documents.
1. Whenever they create parked document, entries will be stored in BKPF(Parked Document-Filed-BKPF-BSTAT = 'V') and Bseg....
2. I have to read entries from those tables and should create IDOC...
3. I checked FM's(FI_IDOC_CREATE_FIDCC1, FI_IDOC_PREPARE) but are not useful...
4. Now I need to write one RFC function module and that FM should create the IDOC's....
Can anyone please help me out?
Thanks,
Sony
