RFC function call

Hi friends ,
I have created on RFC in R/3 to update saftystock in MARC table . when i execute this in SE37 it is updating the MARC table . The proble is when i execute this RFC from BW system with the
   CALL FUNCTION 'ZSCPI033' destination 'TCOCLNT101'
EXPORTING
BAPI_HEAD         =
BAPI_MARC1        =
BAPI_MARCX        =
IMPORTING
   BAPI_RETURN        = V_RETURN1
TABLES
    INT_MAT           = t_process
It is updating the record in MARC table of R/3 system with the value 0. BAPI_return type is showing 'S'.
can anybody help me on this pls.
Regards
prithvi.

Hi
Kindly do coding
put a COMMIT WORK after the RFC
if l_failure = 'X' .
      rollback work .
      message i000 with reservation ' : Data not saved! '.
    else.
      commit work .
      message s000 with reservation
          ' : successfully saved! '.
    endif.

RFC Function Call - System not available

Hello,
in my own program i´m using an RFC function call to get data out of our BW - System like this:
CALL FUNCTION 'RRW3_GET_QUERY_VIEW_DATA' DESTINATION i_dest
    EXPORTING
      i_query               = i_query
      i_view_id             = i_view_id
      i_t_parameter         = i_t_parameter
    IMPORTING
      e_axis_data           = gt_axis_data
      e_cell_data           = e_cell_data
    EXCEPTIONS
      system_failure        = 1
      communication_failure = 2
      OTHERS                = 3.
This works fine and fast as long the BW System is up and running. If the BW system is for some reason down my program has very bad performance because this RFC function call is trying for about 10 seconds every time.
Is there a way to avoid this long waiting time? A kind of parameter?
If there is no answer after one or two seconds the programm should continue.
Any ideas for this?
Thanks a lot.
Best regards
Manfred

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.

Can we disable implicit DB commit in JCO RFC function call?

I called RFC function provided by ABAP from JCo connection, found that each RFC function is a db LUW itself. All the db access sql in RFC function is implicit commited.
Till now, to wrap the db access sql in seperate "Update function module" or "Perform on commit" seems to be a choice for me (like most BAPI doing so). But is it the only choice?
The point is, can we disable(or bypass) the implicit DB commit while calling a RFC function from JCo connection?

Hi Guru,
Yes you approach is correct, make sure commit/rollback is possible only when a change is/was made in database.
Go through these links will be helpful,

RFC function call from VB Script

I have an RFC enabled function that I need to call from VBScript. I was working through this issue as a BAPI call but after research and RFC not initialized error messages over and over I am coming to think that the issue is not how I was doing it but what I was trying to do with different objects.
I think the issue is that I was trying to call a RFC function with BAPI methods, I didnt understand that there was I difference but now I do. I don't know how to initialize the RFC on the host system and unsure if I even have all of the components on the host system to make these function calls.
The goal here is to call a function that passes 3 paramters and modifies a user object in SAP.

Hello John,
are you using DCOM Connector? I have a VBScript working correctly, using DCOM Connector, and consuming a Z function module defined as RFC.
What's the error message you're getting?

RFC Function calls modal dynpro

Hello,
I programmed an outlook addin which calls an abap RFC function to store the email with sap content. Within the function a modal dialog is called to enter some information. The outlook addin is waiting for the function to add some information to ms outlook. This handling has three big disadvantanges. 1. the dynpro is opened in the backgound of the outlook window. 2. the modal dynpro has no button in the task band. 3. The dynpro is not bound to the outlook window.
To get the dynpro in the front you need to lower some other windows or you have to use the ALT TAB function to click through all windows. The RFC function gets the windows handle by the outlook addin but I dont know how to handle it? Can I bound the dynpro to the outlook window so that if I click on the outlook button the dynpro will appear? Can I give the focus to the dynpro? Is there any better idea to handle this problem in a better way?
Thanks in advance for any suggestion...

How to handle JCO Exceptions at JCO (RFC) function call

Hello Forum,
I am implementing an JCO Server scenario.
I use dynamic repositories like Example7.java from the JCO documentation.
Example7 throws an JCO.AbapException if anything went wrong, e.g. the function is not implemented.
How to react on this AbapException?
The examples in SAP Help documentation only catch
SYSTEM_FAILURE and COMMUNICATION_FAILURE.
All other RFC modules I have seen which declare the function modules to be used by dynamic JCO repositories (like Example7.java) do not define any other Exception parameters.
But these two are only thrown and caught when something with communication went completely wrong, e.g. RFC not found.
But when RFC can be reached and the JCO Server is executing the Java method, an AbapException could be thrown on error. How to react on this?
In my implementation based on the examples I always get a ABAP dump. The dump says:
Exception named without message text. Why that name?
How to handle this type of exception in order to avoid the dump?
Can anyone post an example please?
Thanks,
Carsten

Hi Micky,
thanks for your quick response.
If so, to throw JCO.AbapException on JCO Server side is not correct?
What I do is throwing the JCO.AbapException (like in the JCO Example 7).
At the RFC call in APAB I handle both exceptions SYSTEM_FAILURE and COMMUNICATION_FAILURE like
CALL FUNCTION 'MY_JCO_FUNCTION_MODULE'
    DESTINATION JCO_DEST
    <...>
    EXCEPTIONS
      SYSTEM_FAILURE        = 1 MESSAGE RFC_MESS
      COMMUNICATION_FAILURE = 2 MESSAGE RFC_MESS.
This works as far something with RFC is wrong, e.g. Server can not find the function or Server not reachable.
But the AbapException thrown by the JCO Server (Java) is not handled that way. Why?
Sorry if this is the wrong forum but I tried posting in Netweaver integration and got no answer for 1 week and because it's ABAP related I thought the topic suites here.

Possible checks before RFC Function Call

Hello everyone,
I have the problem, that one of my transport requests was denied to transport into production by our QA, because I didn't check, if the RFC FM (it was a BAPI to be exact) exists in the target system and I didn't handle the RFC exceptions.
Can someone tell me what this means, and to be sure, what additional checks can be done before calling a remote enabled function module? Code snippets are more than welcome!
Thanks in advance,
Alej
PS: Points will be rewarded!

Hi,
variables declared in the top include of the function group is available to all the function modules in the group during runtime.

How do I retrieve records from a table using JCO RFC Function Call

Hi
I am totally new to SAP Java Progamming. And I would like to know if I am writing code correctly. I read some tutorials in the Internet but I am still not sure if I am doing it the correct way.
This is what my vendor has given me.
My question is whether this is the correct optimum way to do get the customer detail based on an array of input values for the customer reference number.
Input:
I_CUSTNO - Any number customer IDs. This is a table similar to I_CUSTDETL
Output:
Structure name: I_CUSTDETL
Note: The CUSTID column has been added in the structure to identify the address of the relevant customer id
Field details:
Field Name Data Type Length
CUSTID       Character   10
COMPANYNAME   Character   40
EMAIL        Character     40
This is my code:
        JCoFunction function = connect.getFunction("Z_GET_CUSTOMER");
        JCoTable cust = function.getTableParameterList().getTable("I_CUSTNO");
        cust.appendRow();
        cust.setValue("CUSTID", "10000700");
        cust.appendRow();
        cust.setValue("CUSTID", "10000701");
        cust.appendRow();
        cust.setValue("CUSTID", "10000702");
connect.execute(function);
        JCoTable table = function.getTableParameterList().getTable("I_CUSTDETL");
          System.out.println("Table size: " + table.getNumRows());
          for (int i = 0; i < table.getNumRows(); i++, table.nextRow()) {
            String custid= table.getValue("CUSTID").toString();
            String companyname = table.getValue("COMPANYNAME").toString();
            String email = table.getValue("EMAIL").toString();
            System.out.println("----
            System.out.println("Record Number::" + i + "::");
            System.out.println("----
            System.out.println("Value custidis::" + custid+ "::");
            System.out.println("Value companyname is::" + companyname + "::");
            System.out.println("Value email is::" + email + "::");

Hi,
Answer to your question :whether this is the correct optimum way to do get the customer detail based on an array of input values for the customer reference number? is
YES.

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..

Python sapnwrfc FUNCTION CALL ERROR

Hi everyone,
I am trying an external rfc connection with sapnwrfc-0.05 for Python. I have the latest nwrfcsdk from SAP. It took me a while to figure out the new python module methods, but I am now able to connect successfuly.
I have a function module that I need to call and feed external data to it. This function is writing to a Z table of mine. I have done this successfuly with previous versions of python sapnwrfc module.
Here is my test code:
import sapnwrfc
conn = sapnwrfc.base.rfc_connect({'ashost':'HOSTNAME', 'sysnr':'00', 'client':'900', 'user':'RFCUSER', 'passwd':'PASSWORD' })
if conn :
    print "I am connected"
#    VBELN = CHAR
#    LNUMB = NUMC
#    WERKS = CHAR
#    GJAHR = NUMC
#    HEAT = NUMC
#    ZIERA = CHAR
#    ZLENG = CHAR
#    ZWEIG = CHAR
#    ZINDX = CHAR
#    ZPDA = CHAR
#    ZTIME = CHAR
    data = [VBELN+LNUMB+WERKS+GJAHR+HEAT+ZIERA+ZLENG+ZWEIG+ZINDX+ZPDA+ZTIME]
    iface = conn.discover("MY_Z_FUNCTION_MODULE")
    f = iface.create_function_call()
# MY_Z_FUNCTION_MODULE has a TABLE structure DATA
    f.DATA(data)
    f.invoke()
    print "Done"
    conn.close()
When I run this code I get the following ERROR:
File "/usr/lib/python2.4/site-packages/sapnwrfc/__init__.py", line 165, in invoke
    return self.handle.invoke()
sapnwrfc.RFCCommunicationError: RFC FUNCTION CALL ERROR: set_table_line invalid Input value type
The same function module was working before, when called with DATA as a single string item in a list.
Any help?
Thank you all.
Menelaos

As I discovered, you need to supply the DATA table structure with a dictionary of its field values:
data = [{'VBELN':VBELN,
            'LNUMB':LNUMB,
            'WERKS':WERKS,
            'GJAHR':GJAHR,
            'HEAT':HEAT,
            'ZIERA':ZIERA,
            'ZLENG':ZLENG,
            'ZWEIG':ZWEIG,
            'ZINDX':ZINDX,
            'ZPDA':ZPDA,
            'ZTIME':ZTIME}]
Just make sure that each field has the correct size. The data types in the dictionary should all be strings, but the string contents should match the field types of the DATA table structure....
This is really an improvement over the old method (single string) but some documentation would be helpfull Piers!
Can I help?

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.
Thanks,
Augustin.

ABAP Dump due to RFC Function module call in another thread

Hi,
I am facing some problem since yesterday. In one of my executable program I am calling a RFC fm as below mentioned
REPORT ZREPORT.
CALL FUNCTION 'Z_XXXXXXXXX'
      STARTING NEW TASK L_NAME
      DESTINATION IN GROUP 'TASK'
      PERFORMING RETURN_INFO ON END OF TASK
      EXPORTING
        P_exp1       = l_emp
      TABLES
        R_VBELN      = r_it_vbeln
      EXCEPTIONS
        NO_DATA_TO_PROCESS = 1
        OTHERS             = 2.
wait until v_task = 1.
update ztable.
Due to some data inconsistence one of the SAP function
module which I am calling in my function module Z_XXXXXXXXX
is generating dump with message type X. Since there is data inconsistence it is generating dump that's OK.
But the problem i am getting is, report ZREPORT is generating dump at WAIT statement saying illegal statement even though I am calling that function module
Z_XXXXXXXXX as a separate new task.
Can somebody help me.
Thanks,
Amara.

hi, Amara
I agree with Rich said, and do a simulate test in my server, here is the analysis.
Assume we have a RFC, like this:
FUNCTION ZGZL_DUMPTEST.
*"*"Local interface:
*" EXPORTING
*"     VALUE(OUT) TYPE I
*" EXCEPTIONS
*"      CONVERT_FAIL
data:a type i.
a = 'A'.
ENDFUNCTION.
And call this RFC like you way:
REPORT ZGZL_DUMPTEST .
DATA:
SEMAPHORE(1) VALUE SPACE,
LC_OUT       TYPE I.
CALL FUNCTION 'ZGZL_DUMPTEST'
STARTING NEW TASK 'DUMP'
PERFORMING RETURN_INFO ON END OF TASK.
WAIT UNTIL SEMAPHORE = 'X'.
WRITE: 'OVER'.
FORM RETURN_INFO USING TASKNAME.
RECEIVE RESULTS FROM FUNCTION 'ZGZL_DUMPTEST'
          IMPORTING OUT = LC_OUT.
SEMAPHORE = 'X'.
ENDFORM.                    " RETURN_INFO
if we run the RFC in se37 directly, obviously it will occur a rumtime error CONVT_NO_NUMBER, and dump.
But if we run the above application to call the RFC, we will get a different runtime error CALL_FUNCTION_REMOTE_ERROR.
Error Analysis in ST22 like this:
An error occurred when executing a REMOTE FUNCTION CALL.
It was logged under the name "CONVT_NO_NUMBER"
on the called page.
I think that means the application receive the runtime error from RFC when call <b>RECEIVE RESULTS</b>.
In normal CALL FUNCTION, the external application will accept the rumetime error throw from FM, that's correct, because it let the caller can handle these runtime errors.
In you case, you said RFC run in a new task, yes, that's true, so you can call the RFC like this:
CALL FUNCTION 'ZGZL_DUMPTEST'
STARTING NEW TASK 'DUMP'
PERFORMING RETURN_INFO ON END OF TASK.
WAIT UNTIL SEMAPHORE = 'X'.
WRITE: 'OVER'.
FORM RETURN_INFO USING TASKNAME.
SEMAPHORE = 'X'.
ENDFORM.                    " RETURN_INFO
It will goes well, no dump. Why? because we don't use RECEIVE RESULT. RECEIVE RESULT will bring the result from FM, also bring the runtime error from FM.
So if you want to call the FM and receive the result, handle the runtime error in FM inside at first.
like this:
CATCH SYSTEM-EXCEPTIONS CONVT_NO_NUMBER = 1.
    a = 'A'.
ENDCATCH.
IF SY-SUBRC = 1.
    RAISE CONVERT_FAIL.
ENDIF.
And then you call FM like this:
CALL FUNCTION 'ZGZL_DUMPTEST'
STARTING NEW TASK 'DUMP'
PERFORMING RETURN_INFO ON END OF TASK.
WAIT UNTIL SEMAPHORE = 'X'.
WRITE: 'OVER'.
FORM RETURN_INFO USING TASKNAME.
RECEIVE RESULTS FROM FUNCTION 'ZGZL_DUMPTEST'
          IMPORTING OUT = LC_OUT
          EXCEPTIONS CONVERT_FAIL = 1.
SEMAPHORE = 'X'.
ENDFORM.                    " RETURN_INFO
That's will be ok for your scenario.
Hope my reply is useful.
thanks

Is it possible to call custom designed RFC function module, apart from BAPI

Hi Friends,
1. Is it possible to call custom designed RFC function module, apart from BAPI.
2. Why we call it Adaptive RFC layer, Since every time the JCO layer updated with SAP, Why cant be dynamic.
Thanx for Ur time.
Cheers,
Sam

Also check <a href="http://help.sap.com/saphelp_nw04/helpdata/en/41/38bc8f813719488ddc9d9b21251ec3/frameset.htm">here</a> for more information on aRFC. Here you can find why it is called adaptive.

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.

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.
