Transactional RFC Monitoring

hi all,
   Can anyone explain to me how transactional RFC works? As what i've understand it, the first transaction to get in is the first to be executed right?
   Here's my scenario. I always monitors the transactional RFC,and from time to time, I observe irregularities. For example, at arround 9:00 am, bunch of transactions are displayed and the status are "status recorded". By 11:00 am, transactions are added again but this time one of the status of transactions timed 11:00am is "status executing" even if there are still remaining transactions that are recorded by 9:00 am. The way i understand it, the "first in" "first out" here was not applied.
   Could anyone clear this? am i right about the "first-in first-out" scenario? if yes, how can i correct tmy problem? If not, can you explain??
Your response is highly appreciated.
cheers,
Jay

Hi Jay,
As given in the RFC adapter help
Transactional RFC calls (tRFCs) in messages with quality of service Exactly Once (EO)
The tRFC in SAP sense means:
This scenario is suitable if the data being sent is not interrelated. A calling application (or client) in system 1 uses a tRFC connection to a called application (or server) in system 2. In this scenario, the data is transferred using tRFC. This means that each function module sent to the target system is guaranteed to be processed once. The order in which the function modules are executed, and the time they are executed, cannot be determined. If a transfer error occurs, a background job is scheduled that resends the function module after a defined period of time.
What you are talking abt is EOIO. As per the RFc adapter help, it supports:
Transactional RFC calls (tRFCs) in messages with quality of service Exactly Once (EO)
The receiver RFC adapter can also process messages with quality of service Exactly Once In Order (EOIO). They are mapped to transactional RFC calls (tRFC).
Hope this is of some help.

Multiple RFC calls in same session

Hi All,
I'm looking for a way to execute multiple RFCs (one after the other) within the same "session". The reason I need to execute them within the same session is because the initial RFCs store information in ABAP memory (EXPORT x TO MEMORY ID y) and subsequent ones will use that information (IMPORT x FROM MEMORY ID y) for further processing. I thought I could do it all as a transactional RFC call but as one of the RFCs invokes the GUI, it seems to cause complications. I don't think tRFCs are the correct solution because it invovles client interaction from the GUI in one of the calls.
Has anyone tried to do this with the .NET Connector before? I've tried reusing the connection but it seems to get reset after the first call. Please help!
Tim.

Hi Tim,
How are you doing ?
A session [when using NCo] is the length of time that the connection is open.
please let me know why the connection is being reset.
the client number is a mandatory attribute in any connection string, it is a part of a composite key which uniquely identifies the user
please let me know how you would like to proceed ?
with respect,
amit

RFC call do not return any value

Hi All,
I have an RFC written in one R/3 system(call center R/3) and i am calling this RFC in the ERP system.
If i try to run the RFC locally in the call center system ,it runs correctly and returns me proper values.
But when i try to call it from other R/3 system(ERP) the RFC does not return value.(both cases i am passing same parameters).
Also , RFC parameters are defined with pass by value option.
I am not able to trace why this behaviour,can anyone pin point what could be the possible cause of error.
Thanks in advance,
Swati

No ,there i snot RFC connection problem ,i have checked it from SM59.
Neither do i get any dump or error of no authorization.In fact the sy-subrc after the RFC call is 0.
St22 do not have any trace for the same.
my RCC call is something like this,
IF dest <> ' '.
CALL FUNCTION 'Z_GET_CIC061' DESTINATION dest
                  EXPORTING
                       p_comp        = itab_cic-company
                       p_asc_code    = itab_cic-customer
                       p_wbill_no    = itab_cic-bill_no
                  IMPORTING
                       e_tr_no       = tr_no
                       e_model_code = model_code
                       e_data_origin = data_origin
                 EXCEPTIONS
                         communication_failure = 1
                         system_failure        = 2.
ELSE.
            MESSAGE i000 WITH 'RFC Destination is empty!'.
            EXIT.
          ENDIF.
Can anyone please suggest whats wrong in the above code.
Also what is transaction RFC call?is it related to what i am using in the above code of mine.
Thanks in advance,

Error during loading of transaction data: An RFC call-up triggered the ...

Dear Sirs,
during loading of master data from a 4.6C SAP system to BI 7.0 SP9 I get the following error during processing (data packet).
<i>"An RFC call-up triggered the exception (ID: RSAR NO: 503) "</i>
The strange thing with this error is that it emerged today, after successfully loading master data and a subset of transaction data yesterday from same source system.
Has anyone else come across this error, and can tell us where we should look for a possible solution? (or a better error explaination).
The RFC connections works fine when testing in SM59, and was functioning yesterday. No relevant dumps in either system.

Hi folks,
I am also interested in this error.
Thanks.

Invoke MII Transaction thru RFC Call from SAP

Hi,
We want to get the data from Oracle DB table thru MII (12.0.2).
We need to use RFC call from SAP to MII.
Is it possible to invoke the MII transaction thru RFC by setting in Message Listener?
We have used iDoc messages but not tried with RFC.
How to do that?
Regards,
Senthil

I feel MII doesn't have anything equivalent to RFC in ECC. You may try web services in an ABAP program
Hope the article below helps you

How can I access RFC data in transaction? (SAP to MII rfc calling)

If I keep the incoming RFC calling by message rules with category, then using the message actions to handle, that is a solution.
But if I want process the incoming RFC data in transaction directly, how can I get these data?

You will need to define an XML typed Transaction input property for processing the message synchronously. Then in the processing rule for this message you need to associate the proper transaction and map the parameter.
So essentially the transaction and input parameter mapping in your message services processing rule replaces the category setup that you already have working.

Transactional RFC material (urgent)

Hi gurus,
i need some good matrial on Transactional Remote Function Call. Please provide me the same,
any help will be highly appreciated
Regards
vj

hi vj,
Transactional RFC
1 This type of RFC was renamed from asynchronous to transactional RFC, because asynchronous RFC has another meaning in R/3 Systems.
2 The called function module is executed exactly once in the RFC server system. Each function call is seen as a transaction in the target system.
3 Transactional RFCs use the suffix IN BACKGROUND TASK. The remote system need not be available at the time when the RFC client program is executing a tRFC.
4 The tRFC component stores the called RFC function together with the corresponding data in the R/3 database, including a unique transaction identifier (TID).
5 If a call is sent, and the receiving system is down, the call remains in the local queue until a later time.
6 The calling dialog program can proceed without waiting to see whether or not the remote call was successful. If the receiving system does not become active within a certain amount of time, the call is scheduled to run in batch.
7 The system logs the remote call request in the database tables ARFCSSTATE and ARFCSDATA with all of its parameter values. You can display the log file using transaction SM58.
8 When the calling program reaches a COMMIT WORK, the remote call is forwarded to the requested system for execution.
9 Transactional RFC requests are transferred, with parameter data in byte-stream form, using TCP/IP or X400.
10 LUW's are identified by transaction ID's that are unique world-wide. The transaction ID can be determined from an ABAP program by calling function module ID_OF_BACKGROUNDTASK. (You must call this function after the first asynchronous CALL, and before the related COMMIT WORK.)
11 The system function module ARFC_DEST_SHIP transports the data to the target system and the function module ARFC_EXECUTE executes the stored function calls. If an error or an exception occurs during one of the calls, all the database operations started by the preceding calls are rolled back and an appropriate error message is written to the file ARFCSSTATE.
12 Once you have identified the ID of the LUW, you can use the function module STATUS_OF_BACKGROUNDTASK to determine the status of the transactional RFC.
13 Call transaction SM58 (Tools _ Administration _ Monitoring _ Transactional RFC). This tool lists only those transactonal RFCs that could not be carried out successfully or that had to be planned as batch jobs. The list includes the LUW ID and an error message. Error messages displayed in SM58 are taken from the target system. To display the text of the message, double-click on the message.
14 If a LUW runs successfully in the target system, the function module ARFC_DEST_CONFIRM is triggered and confirms the successful execution in the target system. Finally, the entries in the Tables ARFCSSTATE and ARFCSDATA are deleted.
DISADVANTAGES
1 These can reduce performance significantly in both the send and the target
systems.
2 In addition, the sequence of LUWs defined in the application cannot be kept. Therefore, there is no guarantee that the transactions are executed in the sequence dictated by the application. The only guarantee is that all LUWs are transferred sooner or later.
SYNTAX
Eg : CALL FUNCTION remotefunction IN BACKGROUND TASK
CALL FUNCTION func IN BACKGROUND UNIT
parameter_list. The field dest can be either a literal or a variable. Logical destinations are defined in the RFCDES table via transaction SM59 or via the menu path: Tools ->Administration,Administration->Network->RFC destinations.

Fail in RFC call to PI

Hi,
I have a problem with communication of RFC call and PI
The situation is:
ECC calls RFC from report and by the background method with destination to PI.
but...the rfc stays fixed in transaction SM58...and the PI don't receive any message...
The message in SM59 call transaction is:
com.sap.aii.af.rfc.afcommunication.RfcAFWException: lookup rfc sender sm58
We have used the follows structure:
PI 7 with SP 9 - AIX + Oracle
SAP ECC 6.0 - AIX
Thank''s a lot for any help...
Sandra

Hi Sandra,
Great! I'm glad this worked.
I would only use this as a temporary solution though.
This happened because the SAP R/3 Business System that you've specified in your Integration Builder Configuration doesn't match the system (SID and client) that you're sending from. I would recommend correcting the Configuration and then checking this flag again. It's safer that way, because right now you could make calls from any R/3 system and XI would accept it.
To correct the Configuration, you'll likely need to:
1) Create a Business System for the R/3 system that you're making the RFC call from. If it's DEV client 100, you would create a Business System called DEV_100 for example.
2) Redo your configuration with this Business System.
3) Check the 'Verify Sender System' flag again in your configuration.
Thanks,
J Wolff

It is possible to get a response of a asynchronous RFC call thru wait loop

Hi Experts,
The requirement is that i queue up all the requests from a web services ( One queue per plant for example) which i set in the HTTP sender URL ( i mean the queue name ). and i am posting the records thru a RFC call.
1. Let the RFC call be synchronous and in case the R/3 system is done.. Will the XI queue keep the Call and keep on retrying it till the R/3 system is up.
2. Otherwise if the RFC call be asynchronous, is it possible to introduce a wait loop in BPM to listen to the RFC till i get some response ( i think this is not possible).
Need your suggestion on the same...
The requirement demands that no single request from the web service should be lost.. in case of failure of R/3 they should be queued up and re tried.. Forget about the error because of exception in RFC this will be taken care manually..
Thanks for your response in advance.

Hi Rajesh,
you can queue and restart only asynchronous messages. I think you can build a Business Process, where you repeat sending a message til you have success or maximum number of tries is reached. But no good idea, coz you will get timeout at HTTP sender. Aynchronous messages dont have a response.
May be, XI can solve your task in the standard: In transaction SMQR you can just configure what you describe. All asynchronous messages will be queued and restartet in case of receiver not reachable. You can configure no of retries and intervall between.

Error in starting SAP GUI as part of an Java RFC call from a PC

Hi,
We are on the 4.6C version of SAP and have the latest basis kernel patches that allow an RFC connection to start the SAP GUI. The program that I am running externally is java using the 3.0.1 JCo. The OS of the PC I am using is Windows XP. The SAPGUI version is 7.10 patch level 11.
The program seems to be working properly as the command prompt window goes grey as if there is another window being opened but then I get back this error message and I do not see the GUI.
The message I am getting back is:
Exception in thread "main" com.sap.conn.jco.JCoException:(136) JCO_ERROR_ILLEGAL_STATE:Launching SAP GUI failed, though it was requested(error message:Communication with SAPGUI timed out)

Thank you in advance for any information you can pass on about the issue,
Mark

Hi Greetson,
Thank you in advance for your response. It is greatly appreciated.
1) In a way yes. I am using the connection setting USE_SAPGUI = 1. This is suppose to start the GUI prior to starting the RFC's program run. If this is not correct please let me know.
2) The code is part of the JCo and the RFC library from what I have read. If this is not correct please let me know.
3) I am only testing from my PC at this moment. I have re-installed my SAP GUI and am now at patch level 13 on 7.10.
4) The application passes in the connection information which includes username and password along with the parameters for the RFC call. I would like the SAP GUI to open without the user having to re-enter his/her username and password. I thought that once the RFC is called using the dialog users credentials that the GUI would then open using the connection. I have used the java pooled connection method and it still does not open the GUI.
5) The purpose is to pass Equipment objects, Functional Location objects and Leak Id objects to an RFC to open a list screen from IW39, List Maintenance Order transaction, for display of each at one pass, as well as open Excel with data from classification for the Leak Id's.
Hope this sheds some light on the problem I am having. Please let me know if more information is needed.
Best regards,
Mark

RFC calls with SAP table insert - lock tables

Hi,
I have an external server program, which is calling a rfc function many times the same time with different transaction types. There are transaction types, which are downloading information from SAP (only send data back to the caller), and there are transaction types which are uploading data to SAP (inserting/updating data on SAP).
The function calls are synchronous as the server needs to get feedback directly. The parallel work processes for RFC calls are limited, so a system overload can´t happen.
The problem now is, if the server is down for while and going to be restarted, it´s opening parallel threads and calls the function in SAP at nearly the same time. That means, it will call the function with upload requests (table must be locked), and download requests the same time.
In the upload requests, the table has to be locked, that it can´t occur that we get wrong entries...
I can only enqueue the table with just two fields... I know, that is almost like locking the whole table, but it´s not possible to lock it in a different way.
I tried to use the enqueue function with the parameter WAIT, but it didn´t help, as there where too many parallel calls and after some seconds, they were ending up with an error (Because the table has been locked by another call).
It seems that it´s trying to lock the table again for all parallel calls at exactly the same time....
The calls has to be synchronous, as the server needs to get the feedback directly. Any ideas how top solve this, that it handles all incoming calls parallel and waits for the table is unlocked again?
Thank you for your help!

Hi,
thank you for your answer!
I have investigated something new yesterday:
I thought at the beginning, that the problem just occurs, when the system work processes are reached. The system has for example set up 15 dialog processes and the external server is calling the function 20 times in parallel. Then we normally need 5 dialog processes more. The system is taking then all 15 dialog processes and the locks got stucked.
That means, that I´ll maybe only get 4 or 5 uploads, which have really been updated the tables. All the others couldn´t get the table locked for their process.
But if I now let the server call the function just about 13 times in parallel, nearly all uploads have been updated the table!
From my point of view, the lock from SAP gets stucked, when the limit of dialog processes is reached. It´s not working in the right way anymore...
The same is happening, when you set up in the system, that only 10 work proecesses can be used by RFC. If I have more than 10, it´s going to be critical with the locks....
WEIRD!
Can anybody help me out of trouble?
Thank you!

RFC call from ECC to SCM -- Debug Steps required

Hello,
The steps being done for this issue is:-
1) In ECC system ,CN22 Transaction Code (Change Networks) --> Click on Schedule (at the Header) and click on SAVE
2) This seems to trigger an RFC call to SCM server (as per the trace log).
3) From SCM, it comes back to ECC server as User 'BATCHRFC'. This has been defined in SM59 correctly.
4) BATCHRFC in ECC system calls an RFC FM 'CIF_PJ_INBOUND' and changed the status of networks to DSEX (date set by External system)
We are trying to understand why is the RFC call being made? I can debug the FM in ECC when an external breakpoint is used.
However, I want to know where in ECC is the RFC call made (to SCM), and how? How can I control it as we do not want this to happen? How can I debug to understand how an RFC call is made?
Your views would be appreciated.
Regards,
Sanjiv

Hi,
What you do is, enter the Tcode, CN22, then in Command window activate debugger by entering /H
It takes u to debugger, from menu > utilities set a break point at Satetment Call Function, it will stop at all the Function modules in debugger, so you can look for the RFC FM in the program where it is called.
And also look for setting in debugger, may be u have some options for RFC FM.
