1.     What is the package structure need to be  followed for creating abap client proxy.
2.     I read some where in the form, it need to be 4 levels. Why is it?
Thank you

Hi
U hav to create a 4 level package structure for client ABAP proxy.
U can create ur on packages
1st level-structure package.
2nd level-main package.
3rd and 4th level-sub packages.
To the 4th level only u hav to create proxy.
The classes and code wil be automatically generated at the time of proxy creation.
I think the 4 level structure bcz while in r/3 everythin in integration builder like software component version and all wil be takin as different levels.
Also u can go through the weblogs in the above replies u got.
Regards
Victoria.

  • Four layered package structure for ABAP proxies

    Hi
    I am trying to generate an outbound ( client ) abap proxy in our WAS 640 based ERP system by pointing to a XI message interface on the XI integration repository. I have a single package ZPROXY ( not a main or a structure package ) created in our ERP system to hold the proxy structures ( classes, interfaces ). I have this package assigned to a transport layer ( a common transport layer through which other ABAP objects are to be transported ). Is it really necessary to have a four layer package structures for proxies to be transported and work in the QA/Production system ?

    Hi Sudheer,
    Can you pls clarify what do you mean by 'four level package structure' ?
    Are you referring to the ABAP structures that get created during creating the proxy by SPROXY transaction ? These structures get automatically created. We simply have to write the code using these structures.
    Or do you mean the 'package' which is mandatory to create a transportable ABAP object ? i.e. transport from Development to Staging and then Production.

  • Sample Client ABAP Proxy Program - PI 7.1

    I created Proxy. I need to call in a Report Program. I am using PI 7.1
    Can anyone send me a sample Client ABAP Proxy program to use with PI 7.1

    Hi,
    >>>Can anyone send me a sample Client ABAP Proxy program to use with PI 7.1
    it's exactly the same as for 7.0 and there are blogs that show such sample reports on SDN
    just do a little search and I'm sure you can find it

  • Abap report for calling abap proxy?

    why do we need  to write abap report for calling abap proxy? i mean what's the use of abap report and what are the things inside the report ...please give me details about abap report.

    Hi,
    In SPROXY for your outbound interface you generate the proxy class.
    The ABAP report is used to fill the data from the ABAP tables and then trigger the call to XI using this class.
    Look into the code in this blog and check what is done,. The data is filled in the report and then the call is made to XI using an object of the class created in SPROXY using the EXECUTE_ASYNCHRONOUS method.

  • 7.1 Client ABAP proxy code sample (outbound)

    Hi guys,
    has somebody implemented new 7.0(7.1) abap proxies using ws runtime?
    Could you please post some sample code of client abap proxy?
    The 3. proxies were quite easy, but I'm a little bit confused in 7.0 and it's ws-rm.
    Thanks a lot, Olian

    Create a client proxy (for eg. the name would be like ZCO_MI_EMP_OUT_SYNC).
    Create a report program for the client proxy.
    report  yh_proxyclient.
    *  tables: ZEMP_DTLS_COPY.
       data: input type zmt_emp_tar1 .
       data: output type zmt_emp_src1 .
       data: client type ref to zco_mi_emp_out_sync .
      output-mt_emp_src-dept_id = 'SAP EP'.
      data wa_emp type zdt_emp_tar_employee.
      data wa_empinsert type zemp_dtls_copy. "ZDT_EMP_TAR_EMPLOYEE.
    try.
        create object client
    *  EXPORTING
    *    logical_port_name  =
      catch cx_ai_system_fault .
    endtry.
    try.
    call method client->execute_synchronous
      exporting
        output = output
      importing
        input  = input
    catch cx_ai_system_fault .
    catch cx_ai_application_fault .
    endtry.
    loop at input-mt_emp_tar-employee into wa_emp.
      write: / wa_emp-emp_id, wa_emp-dept_id, wa_emp-emp_name, wa_emp-emp_address.
    endloop.
      commit work.

    Hello Experts,
    Is it possible somehow to set Dynamic Configuration values to Message Header when calling Client ABAP Proxy from SAP system?

    I managed to get the dynamic header configuration at least with inbound proxies:

  • Package Management for CodeExchange ABAP projects

    Hi CodeExchange ABAP Contributors,
    according to the size of ABAP in the [https://cw.sdn.sap.com/cw/codex/projects|CodeExchange Project Directory Tag cloud] most of the Projects are ABAP based. Some of them like Twibap, ABAP JSON and ABAP OAuth depend on each other. That is also the case if you want to install packages using [SAPLink|http://code.google.com/p/saplink/], then you need in the most of the cases some [Plugin|http://code.google.com/p/saplink/wiki/pluginList] installed. That can be sometimes very cumbersome.
    As a user of Perl, PHP and Ruby I was using their package management systems like CPAN, Pear and Gems. They provide an easy command line interface to install and update packages. In addition they take care about dependencies.
    I think it's time to start working on a Package Management for CodeExchange ABAP projects. Let's call it ABAP Package Management (APM). SAPLink providing the container to exchange the package and ZAKE to handle the download and install can be a good starting point.
    Let's discuss the problem space here and perhaps we also can involve someone who has perhaps already some experience in building a package management system.
    Best regards
    Gregor

    Hi,
    an XML file to be included into the nugg that describes dependencies on a base of Plugin ID, Plugin Name and Version should be enough.
    The XML should be managed by SAPLink, the hard job is to automatically download and install the plugins.
    How to login to CodExch?
    How to download the certified version of the plugin? A project can delete an old version nugg.
    As you said we need a central instance were the plugin version are versioned and identified univocally.
    Indeed we need a page in code exchange or a tool in release page in order to register the current file as versioned.

    Ivan

  • Client ABAP Proxy : how to know which program is calling that service interface proxy

    Hi All,
    I have prepared some client proxy in ECC to communicate with PI.
    But, if I am not wrong, unlike server proxy which is written directly in the class Provider class in SPROXT transaction, in client proxy we write abap code to trigger proxy in SE38 .
    My question is : If I am in SPROXY and looking at any outbound SI, of which proxy is already generated, then how can in SE38  can I find which program is triggering that interface or proxy?

    Hi,
    check below thread for calling client proxy

    Hi,
         Thanks for your input..
       I have also opend the EAR as ZIP file and deleted the existing listing libaries
    apart from the actual implementing Jar and META-INF folder.
    I have tried deploying the Jar for the second time, it is throwing the same error.
    What I did is...Once the EAR is created, I went to Resource perspective in NWDS and copied the EAR from the EAR project and used the same for deployment.
    Is there is anything else to be modified or deleted before deployement?
    Regards,

  • What do you do for client photos

    I've tried several options and have not hit on the right one
    yet so I'm looking for ideas. I have a client that has a wedding
    site and we need to be able to have her upload photos in an album
    for each wedding. the site is ASP VBScript with connection to an
    Access or SQL database. What software packages do you use, or is
    there a good way to tap into free online albums, they must show on
    her site, not on one of the free services. Looking forward to your
    ideas.

    You might look into CoffeeCup Photo Gallery--do a Google
    search and you'll find out about it. Very versatile and
    inexpensive. It is Flash using Javascript.

    Regards,

    HI Amol,
    Did you check the Message type/Message Inetrface names in the Java Proxy ?
    Also check for Receiever Determinations in the configuration.
    I assume that , you have created the Communication Channel under the Business System created as Standalone Java System.. If not check this.
    Go to SXI_CACHE and check for the Receiever Determination created in the Configuration...
    Hope this helps,
    regards,
