RFC function is called with null paremeters on SAP side

I used the new version of .Net Connector 2.0.1.
I created a simple client called RFC function with one table parameter and simple RFC function inserts record to simple table on SAP side.
If I call this RFC function from SAP side the record is inserted to my table with correct value.
If I call this RFC function from NET side the record is inserted with null value.
What's wrong ?
Could anybody help me ?
Code :
SAP side
FUNCTION ZRVFRFCNV.
*" TABLES
*" ITDATA STRUCTURE ZRVNAMEVALUE
insert into ZRVNAMEVALUE values ITDATA.
ENDFUNCTION.
Net side
ZRVNAMEVALUE nam_val2 = new ZRVNAMEVALUE();
nam_val2.Name = "100";
nam_val2.Value = "NORD";
ZRVNAMEVALUETable tblTest = new ZRVNAMEVALUETable();
tblTest.Add(nam_val2);
// for testing : dataGrid show correct values
dataGrid1.SetDataBinding(tblTest, "");
this.sapProxy11.Zrvfrfcnv(ref tblTest);

The problem was in insert statement. I changed insert to modify on SAP side and solved it.

Function module call with destination

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

Rfc function module call error

Hi Abaper,
I'm doing upgrade from 4.7 to ecc 6.0 currently and encounter problem in one of the rfc function module that we used. I've tested the connection to destination using sm59 and the connection is successful.
As an information, in the rfc setting, the target system is not Unicode system.
When I test using se37 and put the rfc destination in my function module call, I always encountered system_error exception. There's no issue with this rfc call before in 4.7 system.
Please help me on this. Thank you.
Edited by: Abraham Bukit on Sep 3, 2008 2:36 AM

Hi,
I had the same issue in the past and solved it in the following way.
If the destination system is not Unicode please try to set the password for the communication user set in SM59 using only upper-case characters and taking into account that the password shouldn't be longer than 8 characters.
Hope this will help.

RFC function module called inside an enhancment section

Callback function is called with sys user context.

1. Create AQ Queue table
2. Create AQ Queue "MyQueue"
3. Start Queue "MyQueue"
4. Register "Subscriber1"
5. Register "MyQueue"."Subscriber1" with Notification URL : PLSQL:\\Mypackage.SP_Callback
Till here everything is fine...
6. Enqueue message into "MyQueue" with "Subscriber1" as recipient.
7. Now AQ notification is fired and as a result Its calling "Mypackage.SP_Callback".
Here the problem is "Mypackage.SP_Callback" is called from SYS user context. i.e if i capture the dbuser its "SYS" who is invoking the AQ notification call back method, "Mypackage.SP_Callback".
Do i have any settings so that "Mypackage.SP_Callback" is called with a specific user account instead of "SYS".
Please help me...

Using RFC Function Module to send data to NON SAP Application

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 ..

Regarding the RFC Function Module call from PI

Hi All,
I am working on one File to RFC interface, in which File adapter picks the file, this file data has to goto 2 function modules in SAP system. For this i added 2 Inbound interfaces in INTERFACE DETERMINATION and I developed 2 RECEIVER AGREEMENTS. In 2 RECEIVER AGREEMENTS i added single receiver RFC Communication Channel.
Now i want assurance that once 1 st function module will execute completely, then only my second function module should be called. Is there any setting that i can do to make this sync?????.
what is the use of Send 'Confirm Transaction' in receiver RFC Communication Channel under Adavanced Mode.
Thanks,
Balu

Hi,
As per you requirement I would suggest to change your scenario as File To Proxy. It will much more easier and 100% sure to process second BAPI only after first gets successful inside the proxy.
Pass the data from file adapter to inbound proxy and then inside proxy code you first call the first BAPI and use commit wrok. Once commit work is successful then you call the second BAPI otherwise rollback the changes.
Example:
Call First_BAPI
<pass the data to it's import export parameters>
Commit work.
if sy-subrc =0.
Call Second_BAPI.
<pass the data to it's import export parameters>
Commit work.
endif.
Note: If you are not very much comfortable with ABAP the discuss this with your ABAP team mate.

Why are static methods called with null references,valid ?

This is my code :
package inheritance;
public class inh6{
     public static void method(){
     System.out.println("Called");
     public static void main(String[] args){
          inh6 t4 = null;
     t4.method();
O/P :
CalledHere t4 is a null reference and yet we are able to call a method on it,why is null pointerexception not thrown.Why are we able to call static methods using null references ?
t4 is null means it doesnot refer to any memeory address,hence how is method() called correctly.
I hope i am clear. :)
Thank you for your consideration.

You can do that because a) t4's type is "reference to inh6" and b) method() is declared static, which means that you don't need an object to call it, just the class. That class comes from the compile time type of t4. The fact that t4 is null at runtime is irrelevant.
So at compile time the type of t4 is inh6 and hence the method is called.Is it ? Had method() not been static a NullPointerException would have been thrown.Correct.
With non-static, non-private, non-final methods, which implementation of the method gets called is determined at runtime, buy the class of the object on which it's being called. If any one of those "non"s goes away, then the method is entirely determined at compile time, and in the case of static methods, there's no instance necessary to call the method in the first place.

Dynamic Function Module call with table parameter?

Hi All,
I'm trying to call FMs dynamically with PARAMETER-TABLE. These FMs are mainly about searching data from inputs and returning internal table as outputs. I managed to pass data into import parameters as query conditions, but still failed to set tables parameter. The code is like below, could you please help me check what's the problem?

Hi Rama,
Yes, I'm not passing value to the table parameter, but that parameter is where I want to retrieve data from FM, not pass value to, so I don't assign any value to ptab_line-value for that parameter.
BTW, I just did some test to pass value to the parameter using the following code and still got CALL_FUNCTION_PARM_MISSING exception:
FM: ZLEAD_CONTACT
parameters:
IMPORT: I_PARTNER TYPE BUT000-PARTNER mandatory
TABLES: OT_CONT LIKE ZLEAD_INFO_S optional (here ZLEAD_INFO_S is a flat structure)
ptab_line-name = ls_import_para-PARAMETER.
ptab_line-kind = abap_func_tables.
create data ref_type type table of (ls_import_para-STRUCTURE).
ptab_line-tables_wa = ref_wa.
ptab_line-value = ref_type.

And the same error if I set parameter using below code:

Portal can not work with abnormal increased /usr/sap/SID file space

hi experts,
I got a problem today on our HR portal.
At first I can't login the nwa, then I checked tha OS of portal, I saw that the file system /usr/sap/SID's used spaces increase very quickly, though I increase the free spaces for emergency use, the portal still can not work and the free space is still missing. I just solved by restart the SAP service.
Did anyone face the same problems before?
System information
OS --> AIX v5.3
Database --> Oracle 10.2.0.2
SAP --> netweaver 2004s SP12.

Hi,
This happens when your archive log file of the application increases,
Check the folder usr/sap/sid/instance/j2ee/cluster/server0/log/archive folder this is the reason for your disk space increase. Just take a backup and delete the files in the archive folder (except temp folder).
The deletion of older archive files is not handeled by SAP, you have to manually delete the archive logs.

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.

Clarification needed on the behaviour of count with null values

Hi friends,
I am confused about the result given by the count aggregate function when dealing with null. Please can anybody clarify about that to me. Here is what i tried
CREATE TABLE Demo ( a int);
INSERT INTO Demo VALUES
(1),
(2),
(NULL),
(NULL);
SELECT COUNT(COALESCE(a,0)) FROM Demo WHERE a IS NULL; -- Returns 2
SELECT COUNT(ISNULL(a,0)) FROM Demo WHERE a IS NULL; -- Returns 2
SELECT COUNT(*) FROM Demo WHERE a IS NULL; -- Returns 2
SELECT COUNT(a) FROM Demo WHERE a IS NULL; -- Returns 0
Please can anybody explain me why the result is same for the first three select statements and why not for the last select statement. And what does COUNT(*) actually mean?
With Regards
Abhilash D K

There is a difference to the logic when using a column name versus "*" - which is explained in the documentation (and reading it is the first thing you should do when you do not understand a particularly query/syntax). When you supply a column
(or expression) to the count function, only the non-null values are counted. Isnull and coalesce will obviously replace a NULL values, therefore the result of the expression will be counted.
1 and 2 are effectively the same - you replace a null value in your column with 0 and each query only selects rows with a null column value. The count of non-null values of your expression is therefore 2 - the number of rows in your resultset.
3 is the number of rows in the resultset since you supplied "*" instead of a column. The presence of nulls is irrelevant as documented.
4 is the number of non-null values in the resultset since you DID supply a column. Your resultset had no non-null values, therefore the count is zero.

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.
