Following tutorials guide you step-by-step to implement this scenario:

 

Building a Composite Business Process from Scratch with SAP NetWeaver Business Process Management - Guide 1:

Exercise A: You are going to sketch the process diagram for the Investment Approval Process within process composer.  This process contains human activities, automated activities, events, and gateways. You are going to maintain the technical properties and make this process run in exercise B.

Exercise B: You are going to bring all process elements together to a running composite business process as well as execute this process as an end user.

 

Building a Composite Business Process from Scratch with SAP NetWeaver Business Process Management - Guide 2:

This guide explains how to modify an existing Web Dynpro Java user interface so that it can be used within a human activity that is part of an SAP NetWeaver BPM process. Web Dynpro Java is the first user interface technology that is supported in SAP NetWeaver Composition Environment 7.1 EHP1.

    Web Service returned an error. Fault Code: "(http://schemas.xmlsoap.org/soap/envelope/)Client" Fault String: "Unable to process the request"



    with following XML content:

        Hi Ram,


        the link https://sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/e06ca88c-79a6-2b10-d29e-ebd8a1e69279 to the ZIP file "Building a Composite Business Process from Scratch with SAP NetWeaver BPM_Source Files.zip" in the first guide works for me. It includes the "purchaserequest4.zip" file. While extracting the "purchaserequest4.zip" file, I got two warnings but they haven't blocked me.
        Please, note that the sources are provided as DCs. To import them, unpack the ZIP files to your local workspace and refresh your Development Infrastructure perspective.


        Please, let me know if you have still problems with the link.

  • Incompatible expression type
    2009-02-08 22:14:24 Chan Jin Park SAP Employee Business Card [Reply]

    Hi, Jie


    Again, thanks for your effor for this. Execrise 2, Step 10 Add the human Activity to view the nofication to your process. step 15. Under Input Mapping,


    DO_InvestmentApprovalProcess/PurchaseOrder siad.
    Expected : PurchaseOrder, ns=http://demo.sap.com/bpm160_execrise_wd/PoNoitify.com


    Found : Purchase Order http://www.example.org/Approval process.


    Based on your screen shot, I am only see the screen Purchase Order http://www.example.org/Approval process.


    which I guess, Process Contet must be point out toe the http://www.example.org/Approval process,but somehow it points to a new crated bpm160_exercise.


    I wonder where I can fix this wrong expression.

  • Great blog! Problems in 7.1.1 beta
    2009-01-30 05:23:44 Rashad Dunn SAP Employee Business Card [Reply]

    Jie thanks for all the valuable learning points in the blog. Contrary to your instructions I tried your process in the 7.1.1 beta version and when the build option for the process is run the following error occurs:-
    Error: C:\Users\i047861\NWDSworkspace.jdi\LocalDevelopment\t2\18018A0000142E9A8DAFB5FD2ACF8B4B\default\logs\unittesting_postbuild.xml:128: Warning: Could not find file C:\Users\i047861\NWDSworkspace.jdi\LocalDevelopment\t\18018A0000142E9A8DAFB5FD2ACF8B4B\classes to copy.
    Is this as a result of not using the trial version or have I done something else wrong?

      Hi Michael,


      Please follow the Instructions below to create this web dynpro project. You can also see the step-by-step instructions with detailed screen shots in Guide 1 (https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/a0886795-eaa0-2b10-7c97-d81b97372327 : step 1 Configuration --> C. Create Web Dynpro Project):
      1. Extract the Web Dynpro project to the path of your workspace (e.g: C:\workspace_beta20.jdi\LocalDevelopment\DCs\demo.sap.com)
      2. In NetWeaver Developer Studio choose window --> Open Perspective --> Development Infrastructure
      3. In the Component Browser View expand node 'Local Development' and 'MyComponents'. Select the node ‘bpm160_exercise_wd’ and with right mouse click to select ‘Sync/Create Project’-->‘Create Project’.
      4. After the project is created, you’ll be asked to switch to the Web Dynrpo perspective to view the Web Dynpro project. Please click on ‘Yes’ to switch to the Web Dynpro Perspective. You can also go to Windows --> Open Perspective --> Web Dynpro to open Web Dynpro perspective directly.


      If this Instructions does not work for you, please let me know.
