Calling Synchronous RFC Function Module in Background

Hi all,
Currently we are working on some requirement where in we have to retrieve data from one system(CRM) and update the same into another system(ECC). We have developed a RFC Function in CRM system and it is being called from ECC system as in synchronous mode via a batch program.
Now since all sychronous call to a RFC function will be dialog there is a constraint on the runtime which is being set by maximum run time for each dialog work process. So my question is there an option to call an RFC function synchronously in background (background task) so there is no runtime performance.
The standard TRFC, QRFC calls in background runs asynchronously and so I am trying to check with the SDN world as whether has anyone tried SRFC(Synchronous) call in background?
Thanks in advance,
Jagath

So my question is there an option to call an RFC function synchronously in background (background task) so there is no runtime performance.
One solution would be to increase the value of the "time out" parameter defined the CRM system. This i feel is not a fool-proof solution as the run-times cannot be predicted. Check this thread: Re: RFC timeout profile parameter
For me a better solution would be to implement tRFC call instead of a synchronous call. Any reasons why you don't want to implement a tRFC ?

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.

Calling a RFC Function Module

Hello Guys,
I have a question regarding calling a RFC function module.
In BW - BI 7.0 I call a RFC function module:
(The ABAP program in BW-BI 7.0 is below)
CALL FUNCTION ''ZTESTFUNCTIONMODULE' " Function module in ECC
     DESTINATION 'DECCLNT110' " ECC system
    TABLES
      it_gl_item   = it_gl
      it_errlog_gl = it_errlog_gl.
The 'ZTESTFUNCTIONMODULE'   is RFC enabled in the ECC system.
The purpose is we retarct the data from BW to ECC.
When I run the function module it always asks for the user id and password.
The SAP logon screen appears and it asks for the user id and password.
The destination is maintained in the SM59 transaction and also the user is maintained there. I think it should login automatically into remote system and return the tables. is it correct. How to skip the logon screen.
Do I have to pass the user id and password in the function module. I think it should take the user id from the SM59 destination. Is it correct.
Please advise. As always thanks for your help guys.

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.

Where should i call the rfc function module? in xi or in r/3

where should i call the rfc function module?
for the synch scenario: file < -- > xi <---> rfc
i know the type of rfc is tcp/ip; but i'm not sure with the followings,
and with some trials i can not even see any message via rwb even all the setting
can be activated without errors.
where should i create the rfc destination? in r/3 or xi
where should i call the rfc via abap program? in r/3 or xi
i guess the calling program should belong to the different server with the rfc itself....
so confused....
Thanks for your reply!!
Jun

if i create the destination in xi point to r/3, then i call the rfc use the destination in r/3 right ?
The call doesnt use the destination in R3. XI has the RFC destination which is just used to connect to the R3 system
but where i need to create the fm via se37? in xi or r/3 ?
In R3

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.

To call an RFC, you need to import that first. For that right click on the project into which you need to add the rfc.
Import >>import RFC modules from r/3>>Give the package name and a port name for the rfc.
set the server options as your r/3 server properties.
Then you can search the Function name >> it will be displayed in the result area>> select it and press finish.
The RFC will be imported to your project.
Then you need to create JCO for calling that rfc.
Here is a sample code which calls an RFC and setting jco..
import com.sap.mw.jco.JCO;
import com.sapportals.portal.prt.component.*;
public class rfc extends AbstractPortalComponent
     private JCO.Client jcoClient;
     Insert_pgm_PortType insFunc=new Insert_pgm_PortType();
     Zinsert_Pgm_Input ip=new Zinsert_Pgm_Input();
     Zinsert_Pgm_Output op=new Zinsert_Pgm_Output();
    public void doContent(IPortalComponentRequest request, IPortalComponentResponse response)
    this.connect();
     insFunc.messageSpecifier.setJcoClient(jcoClient);
//setting input params
     ip.setAssociate_Id1("44");
     ip.setCourse_Objt1(2);
     ip.setQlty_Content1(5);
     ip.setSeq_Content1(2);
     ip.setTraining_Id1("22");
//calling RFC
     try{
     op=insFunc.zinsert_Pgm(ip);
     }catch(Exception e){}
          response.write(op.getMessage());
          this.disconnect();
//creating JCO connection
     private void connect() {
               try {
                    jcoClient =
                         JCO.createClient("Client","userid","password","Language","servername","Systemid");
                         jcoClient.connect();
               } catch (Exception e) {
                    System.out.println("Error connecting to SAP ::" + e.getMessage());
                    e.printStackTrace();
     private void disconnect() {
               try {
                    jcoClient.disconnect();
               } catch (Exception e) {
                    System.out.println(
                         "Error dis-connecting to SAP ::" + e.getMessage());
                    e.printStackTrace();

Jco Call a Function Module in BackGround

Hello All.
Some one can send me a simple exemplo how to call a ABAP Function Module in BackGround.
Can i set this in Java side?
..or only set the BackGround Work Process in SAP side?
In my java application call the Abap Function Module like this:
client.execute(function);
How to set parameters to execute the function in BackGround.
My rpoblem is when the return the data to java side ...occurs the error TIME_OUT in Dialog WorkProcess.
I need to call in background to better performance and to prevent the TIME_OUT.
Best regards.
Taylor.

Hi.
I dont know how to do, but, you can do a previous RFC, this new RFC execute the original function in background mode. I did something like that:
- JAVA: client.execute("RFC_FUNCTION", input, output);
- SAP: RFC_FUNCTION:
CALL FUNCTION func IN BACKGROUND TASK
                     [DESTINATION dest]
                     parameter_list
                     [AS SEPARATE UNIT].
or
CALL FUNCTION update_function IN UPDATE TASK
                             [EXPORTING p1 = a1 p2 = a2 ...]
                             [TABLES t1 = itab1 t2 = itab2 ...].
I hope that help you

Backgroung job failing becuase RFC function module is running in Dialog

Hi,
I have a program which is calling a RFC function module. I am running this program in background as a job. Now this function module which is in other system is running in Dialog and giving a time out error and the job is failing becuase of that.
I tried call fucntion 'test' in background task
destination 'XVZ'
tables
test = 'test'.
But this is not working, i can still see this function module running in Dialog in SM50. Any suggestion?
Thanks,
Shweta

Hi !
RFC-Called function-modules are running in a dialog workprocess of the
target system (they could not run in a batch proecess !!).
That means the do have the same "Timeout" limitations than any other
Dialog-Process.
What you can do:
- The Dialog "Timeout" could ce increased by your SAP-BASIS
- If they could not - you should "shorten" the LUWs in the target-funktion.
...means - put a COMMIT WORK an any point the work is done.
After a COMMIT WORK the "Timeout" Counter beginns at 0 !
Hope that helped....
Reward points would be nice...

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..

PS: This was a simple question, but I guess the reason no one has answered your question is due to the fact that you havent rewarded points to members helping you. Also remember to close your post once it has been answered.

Exception error_message in rfc function module

Hi all,
I am getting a short dump Raise exception in my R/3 system when calling a RFC function module in R/3 for printing a label in LOFTWARE. The error analysis shows the that exception condition 'Nlink exception' condition raised . The rfc destination is working fine and also i have included the predefined exceptions system_failure and communication_failure and also I have used RFC_PING function module before calling teh rfc for printing . Yet it is giving short dump.
I heard that if we include one more exception error_message with return code 99
ie exceptions
    system_failure = 1
    communictaion_failure = 2
    error_message = 99. there will be no short dump.
Can anyone explain me why the return code for exception error_message is not 3 but 99 and also what is the significance of this.
Need your help.

from dump no information is available also it last occured 5 days ago so refreshed from our system..
I want to know what is the importance of the return code 99 here...
can anyone clarify this concept and aslo genrally in rfc exception handling communication_failure and system_failure can handle all type of exceptions then why error_message exception is added with a return code of 99..

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 .

Debugging the Functional Module in Background.

I am calling a Custom Functional module in Background mode using the syntax CALL FUNCTION ZFM in background task.
Can anyone tell how to debug the code using this..
Thanks ,
Yatish

Hello Yatish
You could try to use the following trick:
(1) Put an endless loop into the coding of your function module where you want to start debugging, e.g.
DATA:
    lx_exit_loop(1)     TYPE c.
lx_exit_loop = ' '.
DO.
    IF ( lx_exit_loop = 'X' ).
      EXIT.
    ENDIF.
ENDDO.
(2) Call your function module in background task
(3) Call transaction <b>SM50</b> and search for the background process.
(3) Choose from menu <i>Program/Mode -> Program -> Debugging</i>
Now you the debugger should bring you right to your endless loop. Set lx_loop_exit = 'X' in the debugger and continue (F5 or F6).
Regards
Uwe

RFC Function module is not working in program while Background

Hi All,
we have a one program in BI system which is calling RFC function module. it is executing the program in foreground very well. Same program we have executed in background , it is not working at all. Thiis RFC function module exists in R/3 4.6c system.

Hello Raju,
Transactional call of a remote-capable function module specified in func using the RFC interface. You can use the addition DESTINATION to specify an individual destination in dest. If the destination has not been specified, the destination NONE is used implicitly. Character-type data objects are expected for func and dest.
When the transactional call is made, the name of the called function, together with the destination and the actual parameters given in parameter list, are registered for the current SAP LUW in the database tables ARFCSSTATE and ARFCSDATA of the current SAP system under a unique transaction ID (abbreviated as TID, stored in a structure of type ARFCTID from the ABAP Dictionary, view using transaction SM58). Following this registration, the program making the call is continued by way of the statement CALL FUNCTION.
When executing the COMMIT WORK statement, the function modules registered for the current SAP LUW are started in the sequence in which they were registered. The statement ROLLBACK WORKdeletes all previous registrations of the current SAP LUW.
If the specified destination is not available for COMMIT WORK, an executable called RSARFCSE is started in the background. This attempts to start the functional modules registered for an SAP LUW in their destination, every 15 minutes up to a total of 30 times. You can make changes to these parameters using transaction SM59. If the destination does not become available within the given time, this is noted in the database table ARFCSDATA as a CPICERR entry. By default, this entry in database table ARFCSSTATE is deleted after 8 days.
Thanks and Regards,
SAP Shori
