Hi,

We have developed a comprehensive set of tutorials that show step-by-step how to model a end-to-end process, develop Visual Composer user interfaces for it, put everything together, to assemble, configure, deploy, test and execute the process using CE7.2. This tutorial set is ideally suited to learn about the SAP BPM. In our experience, it will take about half-day to complete all the parts. On completing this set of tutorials, you should have a very good understanding of some of the SAP BPM toolset and how it can be used to create process oriented composite applications.

We start the tutorial with an introduction to the chosen business process namely, Purchase Approval Process and the various layers of a Composite Application and how it maps to a this specific process. Addtionally, we descirbe the various SAP tools set up required for executing the tutorial-Create a Process-Driven Composite Application with CE 7.2 – Introduction.

In the first part we descibe how to model the Purchase Approval Process and create the process context-Create a Process-driven Composite Application with CE 7.2 – Part 1

In the second part we describe how to develop Visual Composer user interfaces for the BPM layer both by modeling and by applying template- Create a Process-Driven Composite Application with CE 7.2 – Part 2

In the third part we describe how to put everything together to assemble, configure, test and exeute the Purchase Approval Process-Create a Process-driven Composite Application with CE 7.2 – Part 3

Should you have any further questions or if you face any difficulties, you are free to contact me

I like the comments/notes along the way. It helps the user understand what is happening in the tutorial rather than just following steps.

I was doing well until the test at step 68. In my Request, the product and description fields are grayed out. I cannot complete the test without entering a product. Is a step needed to activate them for use?

Thanks,
Keith

  Hi Keith,
  
  Did you perform Step 30 where we change the cardinality of these 2 fields?

Hi,

I am not able to access the WSDL mentioned in the Introduction – Step 8. It is prompting for the authorization but it is giving the following error msg and cannot proceed further. Please let me know how to solve this.

Thanks,
Nanda

Error:

Adding to that, i am pretty sure that i have provided the proper authorization details.. but still Error:
com.sap.esi.uddi.sr.api.exceptions.SRExceptionerror code: null detail message: com.sap.esi.uddi.sr.impl.uddi.wsdl.validation.ValidationException: <–Localization failed:

I have read the whole concept and It looks very nice to proceed and unfortunate that i stuck here.. Please throw some light on it..

Hi,
   This seems like a very nice and detailed and down to earth tutorial for getting yourself introduced to the SAP NW BPM tooling. I downloaded the evaluation package and cannot seem to find the process perspective to start working on the tutorial. Is this a known issue with the trial version ?
    Thanks !

           Eduardo.

    Hi,
       Yes. I am on Windows 7 and the links you provided really helped. Just for summary, it is important to:
       a) Make sure the NWDS is installed on the root folder (c:\) as you will have problems with long path names otherwise.
       b) You will need to edit your SapNetweaverDeveloperStudio.ini and add the following 2 lines so that you make Eclipse believe it is running on Windows XP rather than Windows 7:
           -Dos.name=Windows XP
           -Dos.version=5.1
       c) I also had some trouble with Sun JDK 1.6.0_21. Eclipse would not start. If this happens to you, try downloading and older and archived version. In my case, I used Sun JDK 1.6.0_19 and everything worked like a charm.
       Hope these recollection help others on Windows 7 be aware of this little nuances and do not get that frustrated with getting the installation and tutorial going 😉
    
               Eduardo.

Good morning Venky,
thank you very much for the comprehensive tutorial. Is there by chance a similar tutorial available or planned with the use of Web Dynpro in this context?
Thank you,

Hi Venky,

thanks for the tutorial, looks great, but I got stuck with the Service Registry Settings. When I try to import the WSDL from the esworkplace, I get the following error:
com.sap.esi.uddi.sr.api.exceptions.SRException Error Code: null Detail Message: Failed to read wsdl. Reason: Connection reset
I could open the wsdl file in my browser, but here it is not even prompting for the authorization, just the error message. Do you have any idea what the problem can be?

Thank you,

Andrea

Hello!

Got a new problem at part 2, Step 20. Strange, because when I googled it, I found that the problem is usually that people don’t get the Service Endpoints in the list.
Well, I do get my endpoints (or, in this case the only endpoint), but it does not promp for my HU2 username and password, and I don’t get the operations in the lower list. It just says “Could not find the functions metadata.”
And when I cancel the window, it writes these on the console:
0005> [W] Unknown error in service execution
Connection Failed: Check the Network Connections settings or authorization details.
0006> [E] could not get Service Endpoint Operations: Could not find the functions metadata

Any idea? It seems, it can connect to my Services Registry, because everything before these steps works fine, even finds the endpoint, but then it stops somewhere between my SR and the HU2. Or, in my SR.

Thanks
Andrea

  Clear the password cache and try again; maybe then it will prompt for the HU2 username and password.
  
  In Developer Studio, go to Windows -> Preferences and select General -> Security -> Secure Storage. Open the Content tab, select Default Secure Storage and click Delete.

  Hi Karthi,
  
  The URL has changed since the tutorial was last published. There is a link in the note section of step 8 where you can obtain the updated URL.
  
  Otherwise the new URL is http://erp.esworkplace.sap.com/sap/bc/srt/wsdl/bndg_DF5300E043F279F18F0400145E5ADE89/wsdl11/allinone/ws_policy/document?sap-client=800 . The host has changed to erp; previously it was sr2.
