Access data from 2 SAP systems into WebDynpro..Please guide :)

Hello,
Is is possible to access/retrieve data from 2 seperate SAP systems in Web Dynpro?
To ellaborate more:
Under normal situation - We create a Model using which you can access the required BAPI/RFC and using the JCo this connection is complete.
So, in the SLD there is one JCo connection/object for this model.
Now as per my quesry, I want to access data from 2 systems... like CRM & R/3.
So how can I do this:
1. Create 2 seperate model objects and then do Model Context Mapping. If this is rite, then I will have to create 2 JCo connections in SLD.
2. Is is possibe that under one model (example this model is accessing R/3), I need to access data from CRM <i><b>without creatiing another model</b></i>. So that are the possiblities? Secondly is this way/path recommended?If no, how should I proceed.
Hope my requirements are clear
Awaiting Reply.
Thanks & Warm Regards,
Ritu

Ritu,
There is no way you can create single model for 2 different R/3 systems (unless SAP decides to implement this in later versions).
If you still want to stick with a single model approach, I would suggest to use <b>Webservice</b> model where the R/3 interaction part would be taken care by WebService.

    Hi,
    you can create the same...
    but normal practice what we do is create swc for each system so that it is easy to maintain and easy to extend in the future..
    or else follow some conventions if you are just starting the things..

  • Hi All, We are in to Release 11.5.10.2.There is a specific requirement to Prevent users from creating Manual Sales Orders in oracle and yet users should be able to book the Sales Orders Imported from CRM system into Orcale.Please advise.

    Hi All, We are in to Release 11.5.10.2.There is a specific requirement to Prevent users from creating Manual Sales Orders in Oracle and  yet users should be able to book the Sales Orders Imported from CRM system into Orcale.Please advise.

    Thanks for your advise.
    However, I missed to mention that we have two set of users  One is for Finished Goods and another for Spares.
    Only Spares users need to be prevented from creating Direct/Manual Sales Orders in Oracle.
    As you suggested, if this will be done at Form level, that may Disallow FG users also to create Manula Sales Orders which should not be the case.
    Further, I tried to test one scenario through Processing Constraints but it did not work.

  • Tools to Auto load bulk data from SAP BW into Essbase?

    Does any one know what is the most efficient way to retrieve a large amount of data from SAP BW into Essbase on a regular basis? We currenly export data from BW into several Excel files, which has the limitation of 64k row in a batch, we then load the excel files into essbase usng rules files. And it's a manual process. Do you know if there is a better tool/approach that we can use to do the data retrieve and load into essbase in one batch without need of human interference? Thanks for your good ideas!

    you can use HAL to do the extraction and loading data from SAP. did you try this?

  • Pull the data from legacy System into report and display with SAP data

    Hi Friends,
    My requirement is-
    Create report by processing data from SAP tables and prepare output.And Before displaying the output, I have to pull the data from non-sap system which is readymade (It will come as flat file with similar fields as Report structure has) and finally display the records from both SAP and Legacy System by filtering duplicates.

    Steps:-
    Define the file path on selection screen:-
      Selection screen data
        select-options   (s_)
          parameters     (p_)
          radio buttons  (r_)
          checkboxes     (x_)
          pushbuttons    (b_)
    SELECTION-SCREEN  BEGIN OF BLOCK block1 WITH FRAME TITLE text-f01.
    parameter:    p_file    type text_512 obligatory.
    Start-of-selection.
      data : l_fname type string. " File Name
      l_fname = p_file .
      call function 'GUI_UPLOAD'
        exporting
          filename                = l_fname
          filetype                = 'ASC'
          has_field_separator     = '#'
        tables
          data_tab                = lt_data
        exceptions
          file_open_error         = 1
          file_read_error         = 2
          no_batch                = 3
          gui_refuse_filetransfer = 4
          invalid_type            = 5
          no_authority            = 6
          unknown_error           = 7
          bad_data_format         = 8
          header_not_allowed      = 9
          separator_not_allowed   = 10
          header_too_long         = 11
          unknown_dp_error        = 12
          access_denied           = 13
          dp_out_of_memory        = 14
          disk_full               = 15
          dp_timeout              = 16
          others                  = 17.
      if sy-subrc <> 0.
        message e000 with 'Unable to upload file from the PC'(t13).
      endif.
    lt_data is of same structure as the fields in the file.
    For filtering duplicates:-
    delete adjacent duplicates from lt_data.
    Now display the records using either ALV or using write statements.
    You can display the records in any of the way you want.

  • How to Access data from SAP Content Server through SAP Portal

    Hi Experts,
    I want to aceess the data from SAP Content server through portal. Currently I am working on LSO business package. The SAP content server should work like Webdav as we uses KM as webdav.
    I am trying to use this URL into the CMS address but it is not working
    http://XXX-XXX-XXXX:1090/ConTentServer/ContentServer.dll?adminContRep&operation=docIdList&contRep=ZADGAS_LSO
    Is there any other procedure for acceesing the DATA  from SAP content server. ?
    Thanks,
    Ahmad

    If your Content Server is being used by DMS, then you can use the DMS Connector for KM.  This connector allows all documents stored in DMS to be accessed in Portal as if they are stored in KM.  For more info see this:

  • Load the data from Legacy system into CRM

    I'm new to CRM,I would like to know  What is the procedure used to Load the data (ex: Business partners data ,Organization data,Sales data, etc.) from Legacy system into CRM system?
    Can anyone  explain me and send  any documents,it  would be very helpful.
    I highly appreciate your help.
    Thanks,
    [email protected]

    Hi Rani,
    You can also use the ALE IDOC method to load data from legacy to CRM system if you have some middlware tool(E.g. XI) in between. We have implemented this in our project where we were getting flat files from legacy, XI was converting the same into IDOC and the IDOC was sent to CRM where we read the IDOC data, populate the standard BAPI's or function modules to create the data in CRM.
    You need to define an IDOC TYPE similar to the data structure on the legacy system. Maintain the ALE settings. Write the function module to validate and create data in the CRM system.
    E.G. To create business partner SAP has provided BAPI_BUPA_CREATE_FROM_DATA bapi.

  • Method for Downloading Huge Data from SAP system

    Hi All,
    we need to download the huge data from one SAP system  & then, need to migrate into another SAP system.
    is there any better method, except downloading data through SE11/SE16 ? please advice.
    Thanks
    pabi

    I have already done several system mergers, and we usually do not have the need to download data.
    SAP can talk to SAP. with RFC and by using ALE/IDOC communication.
    so it is possible to send e.g. material master with BD10 per IDOC from system A to system B.
    you can define that the IDOC is collected, which means it is saved to a file on the application server of the receiving system.
    you then can use LSMW and read this file with several hundred thousand of IDOCs as source.
    Field mapping is easy if you use IDOC method for import, because then you have a 1:1 field mapping.
    So you need only to focus on the few fields where the values changes from old to new system..
