RFC Function module-With Only Request message

Hi
i need a RFC with only Request message and Response message is not required.
please help me, how to create a RFC function module with out Response message, and it should contain only Request message.
i have created RFC in this way:
RFC doesn't contain neither import nor export parameters. and i have defined one table in TABLE tab which refers to a ztable created already.
when i imported RFC into XI i came to know that RFC has both Request and Response messages, but i don't need Response message.
Thanks in advance..help would be appreciated
Regards,
Rajesh

Thankx Michal,
I have written ZRFC this way:
insert ZMM_AUTO_GR from INPUT_TABLE .
if sy-subrc = 0.
commit work.
else.
rollback work.
im not using neither import nor export parameters..but using only tables parameters. but when imported in XI im getting same table structure in both request an response.
please suggest what changes required in above code to invoke my ZRFC in async way.
you will not get any response in XI- what chages required in my code to dnt get .reponse in XI.
appreciate your help.
Regards,
Rajesh.

RFC function module with call transaction and Import memory ID

Hi,
I am calling RFC function module from R/3 which exists in BW.
In BW stand alone function module works fine.
When I am Calling from R/3 it is not working,
Can you tell me is it because of the below code, And suggest if any corrections required.
I am calling the call transaction and using EXPORT memory iD inside the program
and IMPORT in after that.
And populating RFC table's table " p_i_tcode_user" finally.
set parameter id 'TCD' field p_tcode.
call transaction 'Z_BW_RSUSR002' AND SKIP FIRST SCREEN.
ENDIF.
get the final user data from submitted program
import gt_users_complete from memory id tcode_userid.
LOOP AT gt_users_complete.
      lwa_tcode_user-tcode = p_tcode.
      lwa_tcode_user-uname = gt_users_complete-Bname.
      APPEND lwa_tcode_user TO p_i_tcode_user.
ENDLOOP.
Thanks,
Veerendra.

HI,
   Can you just exaplin it clearly plz..

Call RFC Function Module and return 1000 records at a time

I would like to call a Remote Enabled Function Module from a non SAP system. This function module will select data from the database and return it to the calling program.
Suppose there are 100,000 records that need to be returned, but the calling module would like the data in chunks of 1000 records. Therefore the calling program would call the FM 100 times.
How do I code the function module to know on each subsequent call to grab the next chunk of 1000 records?
Let me know if additional information is needed.
Thanks,
Aaron

Hello,
Here is how you can go for this issue:
1. Create one RFC function module with following parameter. These parameters are with respective of chunking logic.
     Import: Package Size
     Export: Total number of records
     Changing: chunk count
Implement following logic:
1. First of you need to know how many chunks you need to fetch for that get the count of total number of records. This is one
    time activity so you better maintain one flag import parameter will be set to 'X' only first call.
2. Get the number of chunk using total number of records / chunk size for e.g. 1000 / 100 so chunk count = 10.
3. Define internal chunk counter in function module which will be used to locate the correct chunk depending on the chunk
    counter value sent from calling program.
4. Send first call with package size 100 and chunk count = 1, execute select statement and increment internal
    chunk count check if chunk count = internal chunk count in current case chunk count = 1 so exit select statement and return
    with first chunk.
5. Send second call with package size 100 and chunk count = 2. Execute select statement and check chunk count with internal
    chunk counter, in current case it will be 1 so skip that data and go for next chunk of 100 records increment internal chunk
    counter. In this case it will match with external chunk count = 2. load output table with that data and return to calling program.
6. Repeat step 4 until you reach last chunk.
You need to use SELECT...ENDSELECT with PACKAGE SIZE addition so for every loop it will return number of records mentioned in package size.
Hope this helps.

Augustin.

Regarding RFC function module

Hi ,
Our requirement is like this , we have to send the material long text from r/3 to srm system
for this we have developed a rfc function module with srm system as destination .But when we are using this in the program while rfc funtion module is invoked that time it is going to srm system and asking for credentials. how can i supress this .
Thanks in advance.

Hello;
In your RFC destination, you can use a default user.
If you want to use the current user, go check
<a href="http://help.sap.com/saphelp_nw2004s/helpdata/en/22/042860488911d189490000e829fbbd/frameset.htm">http://help.sap.com/saphelp_nw2004s/helpdata/en/22/042860488911d189490000e829fbbd/frameset.htm</a>
It explains how to setup up trusted/trusting system and the use of SSO.

Collection problem with RFC function module WSDL.

Hi.
I have developed an RFC function module in a SAP system version 4.7 (WAS 620). This FM has 2 table parameters. I have no problem when I see the WSDL in the SAP Web Service Browser.
Another team is trying to consume this RFC FM as a web service from a Java application but they say they can't see the table parameters as collections.
Here is the WSDL of the FM, the table parameters are T_MOVIM and T_ERROR:

Should I change something in the definition of the parameters of the FM? or the problem is with the parsing process on the other system?
Thanks in advance.
Fabian.

Welcome to SDN.
I am not sure about this particular issue, but i have used WSDL from WAS6.20 system in MS Office infopath to consume webservice where we have had table parameters without any issue.
may be try with office infopath to make sure that the problem is with the WSDL or with the java application.

IDOC with ABAP - PI Port , RFC Function module

Hi ,
I am creating outbound Idoc in one system, In the same system I am using a ABAP - PI port and assigned a RFC function module.
So when ever the outbound IDOC is created it will go to the port and triggers the RFC function module.
now my question is how to get the outbound IDOC number in the RFC function module.
I thought of reading the table EDIDC with message type, but all previous IDOC's aslo coming .
Regards
Bhaskar

Hi Bhaskar, the IDOC control record or records are transfered to your function module in table paramater I_EDIDC. You could read the IDOC data by calling function modules EDI_DOCUMENT_OPEN_FOR_PROCESS and EDI_SEGMENTS_GET_ALL for each control record.
Regards Jack

Message text available in java using RFC function module

Hello,
I wrote a function module with the ABAP statement
MESSAGE .... RAISING PARAMETER_ERROR
The java developer gets the PARAMETER_ERROR but no
message text.
Is the any way (e.g. exception class) to get the message text also.
Thanks

hi Michael,
In the RFC function module use the table RETURN of type BAPIRET2 and instead of raising the error append the error in RETURN. later in your java code you can read this table RETURN and retrieve the error along with the error text.
Hope this helps.
Regards,
Richa.

Connection closed message by RFC function module.

Hi experts,
I have an RFC function module where I have no own exception defined. I use 'standard' ones.
EXCEPTIONS
communication_failure = 1 MESSAGE ls_proto-message
system_failure = 2 MESSAGE ls_proto-message
Inside this FM I do update of database table using MODIFY dbtab statement.
In some cases I get exception 'Conection closed' as a message.
Does anybody know what this message means?
Could it be temporary connection failure or timeout by table update?
Thanks a lot.

HI,
then it is a temporary failure ..when u get this message ..what u can do is GOTO SM59->try to do a test connection with the destination logical system(Other Sap system)..see if u r able to login...If u r able to login then the RFC connection is fine otherwise we need to check in detail in which cases we are getting the error..

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.

RFC function module always creating BPs with the same user name (RFC user )

Hi All
I posted the below question in a different area before. But thought it would be more suitable here.
Moderators - Please let me know if am doing any mistake.
Question:
I have a RFC function module in CRM that creates Business Partners in ECC (XD01 tcode).
I am using a dialog RFC destination configured in SM59 in CRM.
But my RFC function module in CRM is always creating the Business Partners in ECC with the RFC user id (the user that we maintain for the RFC destination in SM59).
This is a problem for the users because they are not able to track the actual person responsible for creating these Business Partners.
Can somebody please let me know how to solve this problem?
Thanks
Raj

Hi.
You may use the trust relationship between CRM and R/3 and in SM59 instead of set a specific username, you set the flag "current user".
With this flag, the system will access R/3 system with the user logged in CRM system. The Trust relationship must be created between CRM and R/3 in order to the system doesn't ask for a password to login in R/3.
If you need more details please reply.
Kind regards,
Susana Messias

Facing Problem with RFC Function Module

Hi,
I have created an RFC function module to get some data in table format.
I have run the RFC in original system: It is giving the data.
However, when I run this in target system, It is not giving any values.
Could you please let me know, why it happens? I am not sure where I missed out.
Thanks,
Sandeep

HI,
i hope you are calling the RFC function module in the target system like this
CALL FUNCTION <FUNC NAME> DESTINATION <DESTINATION NAME> . The destination should be logical system name of the source Logical system .

Unknown error calling a RFC Function Module in BODI

Hi all,
I am having an issue identifying the error that my batch job in BODI is giving with regards to a RFC function module call in my query. The value returned by the standard parameter 'AL_RFC_RETCODE' are square characters ( ).
At the completion of the job, the error message 'RFC CallReceive error <Function ZCT_INDSLS_SLS_TRN_INSERT: Invalid request.. Invalid request.>.' is being output.
Correct me if I'm wrong but the parameter 'AL_RFC_RETCODE' should return standard values as per the techical manual provided to undertand any errors that might occur during a RFC FM call.
Can anyone help me on this?
Best regards,
Andrew Wong

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.

Atish

Error when call RFC Function module in R/3

Dear All,

I am talking about the above Receiver RFC channel which you guys are using to call R/3 from XI. That where you need to change the commit parameter

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

Getting Return values from RFC function call with visual basic

Hi,
I am creating a sample app to connect to a SAP system which call its RFC functions created with ABAP. It was known that the function will return more than 1 return values.
   SAP Function name ==> "ZFMTP_RFC_GET_RESULT"
        Export parameters (to SAP):
                - Student Name [char 10]         ==> "STUNAME"
                - Student ID         [char 20]        ==> "STUID"
       Return values (From SAP):
                - Results [char 10]        ==> "RESULT"
                - Remarks [char 200]        ==> "REMARKS"
i have managed to get sample codes for connecting and call a RFC function with vb but they only get a return value. How do i retrieve multiple return values like the above function "RESULT" and "REMARKS"?
Here's my vb code to accessing the function
        Dim R3 As Object
        Dim FBFunc As Object
        Dim returnFunc As Boolean
        Dim connected As Boolean
        R3 = CreateObject("SAP.Functions")
        R3.Connection.Client = "000"
        R3.Connection.User = "BCUSER"
        R3.Connection.Password = "minisap"
        R3.Connection.Language = "DE"
        R3.Connection.System = "dtsystem"
        R3.Connection.Applicationserver = "xxx.xxx.xxx.xxx"
        connected = R3.Connection.Logon(0, True)
        If connected <> True Then
            MsgBox("Unable to connect to SAP")
        End If
        FBFunc = R3.add("ZFMTP_RFC_GET_RESULT")
        FBFunc.exports("STUNAME") = "Jonny"
        FBFunc.exports("STUID") = "12345"
        returnFunc = FBFunc.Call() <<== How do i get the return value? or RESULT and REMARKS of the RFC Function?
thanks alot.

Hi Gregor,
Thanks for the link....i am having some doubts with the codes, hope you can clarify them for me if you know the codes..
Below is the code snippet.
Set impReturn = CHPASS_FN.Imports("RETURN") <<=== is RETURN the standard keyword to get a                                                                                return object?
expPassword.Value = currpass
expNewPass.Value = newpass
expFillRet.Value = "1"
''' Call change password function
If CHPASS_FN.Call = True Then
    outFile.Write (", Called Function")
    Message = impReturn("MESSAGE") <<==== So if i have 3 return values..i just replace with the return                                                               value variable names?
    outFile.WriteLine " : " & Message
Else
    outFile.Write (", Call to function failed")
End If
thanks alot...all your help is very appreciated.
