BDC IN RFC FUNCTION

Hi,
I'm calling rfc function in the same system & Client
but with different user id.
This function is calling in background task destination
zz (rfc connection SM59).
this function includes several steps.
one of them is bdc (call transaction) transaction IE02
for creating partners.
sometimes it fails because obligatory data is missing
but I know that function receives the data.
Does anyone could help me ?
thank.

Calling RFC Function module from JAVA

Hi All,
We have created a RFC Function Module for Billing Plan tab in Sales order (BDC). The function Module contains BDC. When we are running the same function module in SAP it is working fine. But when the FM is called in Java , it is allowing only maximum of 5 entries , when we trying to insert at 6th position in billing plan tab, we are getting an error.
Can any one help on this.
Points will be rewarded for helpful answers.
Thanks & Regards,
Kiran I

I think the problem is because of the number of lines displayed on the screen in the BDC session in the Billing Plan.
You might have to add the page down logic to your BDC program.

BDC and RFC

dear all, may I know what is the different between BDC and RFC?

Hi,
<b>
BDC:</b>
Batch Data Communication (BDC) is the process of transferring data from one SAP System to another SAP system or from a non-SAP system to SAP System.
Features :
BDC is an automatic procedure.
This method is used to transfer large amount of data that is available in electronic medium.
BDC can be used primarily when installing the SAP system and when transferring data from a legacy system (external system).
BDC uses normal transaction codes to transfer data.
Types of BDC :
CLASSICAL BATCH INPUT (Session Method)
CALL TRANSACTION
BATCH INPUT METHOD:
This method is also called as CLASSICAL METHOD.
Features:
Asynchronous processing.
Synchronous Processing in database update.
Transfer data for more than one transaction.
Batch input processing log will be generated.
During processing, no transaction is started until the previous transaction has been written to the database.
CALL TRANSACTION METHOD :
This is another method to transfer data from the legacy system.
Features:
Synchronous processing. The system performs a database commit immediately before and after the CALL TRANSACTION USING statement.
Updating the database can be either synchronous or asynchronous. The program specifies the update type.
Transfer data for a single transaction.
Transfers data for a sequence of dialog screens.
No batch input processing log is generated.

RFC</b>
Remote Function Call:
RFCs are requests that an SAP component sends to invoke functions on remote systems, or calls that remote systems initiate to invoke functions on an SAP component.A process that can accept RFCs from SAP components. This allows SAP components to access functions in external systems. In SAP BC terminology, the process is called a Listener. Listeners are one or more threads on SAP Business Connector that wait for incoming requests from SAP components. Listeners are named and register with an SAP gateway to indicate that they are ready to accept requests. Listeners can accept RFC or tRFC requests.
Transactional RFC (tRFC) and Queued RFC (qRFC). tRFC is used mainly to transfer ALE Intermediate Documents (IDocs).
Transactional RFC:
If an error occurs during a synchronous remote function call, the system cannot tell at what point the error occurred (most crucially, whether the function module was actually processed in R/3 before the operation failed). Restarting a failed call is therefore a dangerous thing to do, since you risk duplicating a completed function call.
To alleviate this problem, you can use transactional RFC, which guarantees that each function call you issue will only be executed once, even if you submit it repeatedly to the R/3 System. The system implements this safeguard by assigning a unique transaction ID (TID) to each transaction that you submit. When you attempt to process the transaction, the system checks whether that TID has already been processed. If it has, the transaction is ignored.
Queued RFC:
When you use transactional RFC, you cannot guarantee the order in which the function calls will be processed in the system (it is quite possible that one call might overtake another). For cases where you need to specify a particular processing order, you can use queued RFC, which is an extension of transactional RFC. In qRFC, you place each function call in a logical queue. A function call cannot be executed until all of its predecessors in the queue have been processed. Queued RFC calls are processed asynchronously.
RFC is an SAP interface protocol. Based on CPI-C, it considerably simplifies the programming of communication processes between systems.
RFCs enable you to call and execute predefined functions in a remote system - or even in the same system.
RFCs manage the communication process, parameter transfer and error handling.

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.

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 ..

How to debug a RFC function module remotely from another R/3 system?

Hi experts,
   I have RFC function module in one R/3 system. I am calling this from another R/3 system that is cross apps (Xapps).
   This function module is Synchronous.
Is it possible to debug this function module from cross apps?
Can somebody give me the steps?
Thanks & Regards
Gopal

Hi Shree,
   Can you explain it bit more?
   Do I have to call the function module with "IN BACKGROUND TASK"?
   Or is it that I have to just put external breakpoint in the function module?
   Please help
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

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.

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.

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...

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 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.

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..

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.

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.
