Sap to External System

Hi friends,
I am trying to call a Abap Function Module in C Program.
In my C program i am getting an erro while executing. It has been compiled without errors, but i am facing linker error that "Undefined Symbol _RfcOpen". But i have included the path to the library file librfc32.lib.I am using Turbo C++ Version 1.01.
Can anyone tell me what might be the error.
Regards,
Gowtham K

  • What makes an idocs go out of SAP to external systems.

    Hi Experts,
    I have created many idocs in sap. they are in status of 03 meaning ready to be
    transmitted. but they don't go out of sap, they still remain in queue in sm58.
    If i process it manually it is going. but it should be done automatically.
    what makes an idocs go out of SAP to external systems.
    It is very urgent issue.
    Can any body help in this. Valuable answers will be rewarded.
    Thanks & Regards,
    Satish.

    Hi Sathis,
    Same proble i was faced recently.
    The problem was occured because of error opening an RFC connection.
    you can see by yourself in the following way.
    Goto SM 59.
    Select your appropriate RFC destionation say if destination is assigned  'TCP/IP connection' or 'R/3 Connection', under that select ur destination and press 'TEST <b>CONNECTION'</b> if shows green mark there is no error in connection or it indicates with red there is error in RFC destination connection.
    Suppose if error is occured there is no basic communication setting done between these cleints, if it is case you would be go and talk to BASIS guy and he will make provides destination.
    if any furthore doubts feel free to mail me to [email protected] or reach me 09886869625

    Hi,
    I don't know what is a COSMOS system and I don't know your company....
    You will never get meaningful answers on an internet forum for questions so dependent on your specific environement and requirements. If you know your ECC6 system, then read the COSMOS documentation and ask the COSMOS vendor.

  • Different PO item number in SAP and in external system

    We are sending Purchase Orders to external system via Idoc and receiving dispatch advices (Inbound delivery) from the external systems via Idoc. In SAP PO line items are numbered as 10,20,30....... In the external system the line items are numbered as 1,2,3........
    So when Inbound delivery is received into SAP from external system it is failing due to line item numbers are not matching.
    I got info that this issue can be resolved by using fields E1EDL24-POSNR and E1EDL24-POSEX correctly. I do not know exactly how.The Idoc type used is DESADV.
    Please help with this issue.

    You can see these fields in WE02 when you process with your idoc number.If you want to edit idoc POsnr from 1...10 then you can edit idoc through we19 transaction.
    If you want perminanat solution then check with ABAPer to pass one zero after line item number as your external system passes 1,2....10..etc.
    This can possible check with your technical team.

  • 'Accept IDOC' from external system

    Hi Experts,  I am new to IDOCS. I have to update one already written function module to accept IDOC in SAP from external system. In the function module I see some IMPORT parameters like 'input_method' and 'mass_processing' and EXPORT parameters like 'workflow_result' , 'application_variable' , 'in_update_task', 'call_transaction_done' . Can someone tell me what are these parameters for ???.

    input _method for method of data records update
    Mass_processing for handling the large number of Idocs in single take
    Workflow_result for hitting the results at last
    'in_update_task' update the records in update mode
    call_transaction_done' by using call transaction method it would post the records

  • RFC with External system

    Hi,
    We are trying to develop interface with external system to calculate the shipping costs for a delivery. We will establish RFC connection between SAP and External system.
    Do we need SAP .NET connector to send and receive data from/to SAP. SAO shouls act as client and external system as server. If we have to use SAP .NET connectore, can anyone explain me the detailed process of using SAP .NET connector and connecting to external system.If there is anyother way without using SAP .NET connector, i.e by using RFC function modules, can you please xplain that process too. What is the program ID for RFC destination in SM59?
    I appreciate your help.
    Thanks,
    Ashok.

    setting the program id you need a person with the knowledge of both the system, with the current input it will be difficult to help with that.
    since you are in 4.6C the available options are
    1. DCOM connector
    2. .net connect
    3. JCO
    4. or a plain http call to your external system.

  • Is it possible to integrate LSO 600 with an external system without SAP PI?

    Hi,
    as asked in the title, i am wondering if it is possible to integrate LSO 600 with an external (non-SAP) system without using SAP PI/XI. The external system is a middleware application which can handle RFC functions, IDocs besides the usual web service communications.
    However, i don't know how LSO and SAP PI are integrated so i wonder if their interfaces are such that instead of SAP PI another middleware could be used.

    Web Services are used. If you were to implement the services in your 3rd party middleware and configure SAP to call it, I suppose it is possible. The external course catalog can be used for CourseEnrollment and LearningProgress. See the application help for details. Don't expect to receive support from SAP with such a setup however.

  • Production Order and external system non-SAP

    Dear Friends,
    I need to send a Production Order to a external system no SAP, and upload the information back to SAP,
    SAP does something standard to accomplish this task?
    To send Production Order, I created an IDOC with report RCCLORD, this IDOC contains all information of a production order (AUFNR, WERKS,..) and all operations and materials. But I don't know how to process the information returned.
    Also I have read some information about the interface PP-PDC, but I don't know how to use it.
    Please, Can anyone tell me the best way to accomplish this task?
    this is the scenario:
    SAP R/3 -
    > Production Order -
    > External System
    External System -
    > Return information about Production Order -
    > SAP R/3
    Thanks!

    Hi,
    PP-PDC is for confirmations only, see further details

    Regards,

    Hi Vani,
    First u have set ur Server to Debug mode...then only u can debug the code...
    1. Select "Server0" from J2EE engine (To get this view navigate thru Window--> Show View --> J2EE Engine)
    2. Make a right click on "Server0" and choose "Enabling Debugging of Process"
    3. Now, Navigate to Run --> Debug --> Select your Project as "Webdynpro Application" and click "new" button
    4. Now give some name and Click BROWSE to select ur project and then click APPLY and DEBUG
    Or
    if u use 2004s, then u can do the settings in Portal itself...which gives u more clear information... follow the link

  • SAP R/3 to External System RFC issue

    Hi Experts,
    We have one Peculiar issue in our SAP R/3. Request you to help me in resolving this.
    Order Processing:
    During Sales Orders Processing, for every line item a RFC is being initiated from SAP R/3 to an external system called Trilogy Pricer to get the Pricing data.  Trilogy Pricer sends the Pricing data to SAP R/3 and the respective Orders are being processed in SAP R/3.
    Current Issue:
    The issue we are facing is that, once the Pricing data is sent to SAP R/3, Trilogy Pricer expects an acknowledgement (RFC_OK) from SAP R/3 in order to release the RFC connection.  Intermittently, Trilogy Pricer is not receiving this or any kind of acknowledgement from SAP R/3 causing the connection to hang which is causing several problems.
    For example:
    On every business day, there will be 50,000 Sales orders.
    So, 5 or 10 sales orders are getting hanged every day.
    We tried to simulate this issue in Dev and Stage environments by processing 30,000 to 40,000 sales orders.
    But we were unsuccessful, which means all the RFC connections were being closed as the external system is able to get the acknowledgements for all those orders from SAP R/3.
    We are having this problem only in Prod.
    Any thoughts to solve this issue is highly appreciated.
    Advance thanks for your great help.
    Thanks and Regards,
    Srinivasa

  • How do I integrate SAP R/3 with an external system?

    Hi there!
    I've run into a problem integrating SAP R/3 with an external system. The external system provides a webservice, and when I try to get WSDL file from that service, I am getting asked of authorization and when I authorize, I get error 500. The access is anonymous, as I'm being told. When I try to get just a response, server requests authorization. No matter what login and password I supply, I always get error 401 saying I'm not authorized.
    I think the ICF is somewhat misconfigured, but how do I configure it? Or maybe there's a problem with requests I send. I don't know.
    Please help!
