– Download the ZIP and extract the MSI.
– Installl it. You need Visual Studio 2003 beeing installed.
– Start Visual Studio.
– You see the documentation in “Content”.
– Create or open a VB or C# project.
– Add new item “SAP Connector Proxy” (go down the list).
– Open Server Explorer.
– Select the “Data Connections” node and click on “Refresh” button. Do not right click and select “Refresh”, but click the small button on top of the Server Explorer Window. You should see the SAP root node.
– Add your SAP Server nodes and drag Functions or BOR objects to the designer.

  You need access to the SAP Service Marketplace to download it – meanding you need to be a SAP customer having at least a license of a full product like R/3.

    Hi,
    I tried using the .Net connector as per the documentations provided, but when ever I tried to drag and drop a function module into the designer space it gave me this error
    
    “System cannot find specified path” in the back ground though the “loading data. Please wait” screen is active and the slider is running.
    
    I am able to see contents of BOR and functions specified in my filter, but am not able to drop them into my designer proxy.
    
    Regards,
    Aniruddha

        Sounds to me like an issue with the Path to Java.exe in the registry. Please check that the \JavaHome points to the correct Java home which as bin\java.exe in it.

Is it planned to support dynamic calls for the .NET Connector instead of code-generation ?
If so, in which release will this be available ?

Greetings…

  Dynamic Invoke is currently not planned for the nearer future.

Hello Rainer,
does the new .net connector support the mapping of XML files to IDocs. Then I had to write function which makes this possible. But it is better if the .net connector support them.

  The IDoc serializer is not part of SAP .NET Connector 2.0. We have an in-house prototype of such a feature – but currently no final plans to make a product of it.

    Is it possible to get a copy of this prototype? Perhaps we can create a open GotDotNet workspace for it and contribute to its functionality. I’m sure it would be of great use to many developers.

I have downloaded Version 2 and it is a great improvement over Version 1 – much easier to use and setup. I have tried it with RFC_Customer_Get and it works fine.

If I wanted to use a self written function module with it, how do I relate the file created in that as per BRKNAI/BRKNAITable in the Customer_Get function for example (which are “created” in the new version via drag and drop) as these are the “files” used in the VB.net program.

Thanks

Jim

  SAP Proxy generator will create “Type proxies” for all used parameter types of your function(s).

    Thanks, Reiner – does that mean that the proxy is clever enough to realise what parameters, tables etc are used in the function module and creates an appropriate entity automatically ? If so, do I have to read the code to get the names of those parameters/tables used as per previously mentioned..
    
    I have created my VB.net program with the SAP.net DLLs included but when I load it onto a client PC, it says the SAP connector is missing. It isn’t – as it is in the directory/folder that the program was loaded into. What am I doing wrong or do I have to separately install the SAP.Net connector on each PC that needs it ?
    
    One other thing, can you ask the user to sign onto SAP from a Windows form as well as from the Web version ? If so, how would I do this ?
    
    Thanks again
    
    Jim

      Yes, the proxy generator know which types are needed and creates the necessary type proxies. You don’t need to read code to learn about it: The proxy designer will show you all created types with there fields if you want: Click on the designer background and set the “ShowTypes” property to True.
      
      To deploy a application you need the following DLLs in either your application directory or GAC/System32:
      SAP.Connector.DLL
      SAP.Connector.Rfc.DLL
      LIBRFC32.DLL
      
      Creating a Windows Forms based logon screen is terribly simple: Just drag a destionation to a form (you can drag the server item to get a pre-initialized one and create some text boxes. Then data bind the textboxes to the properties of the destination. If I have time, I will post a sample.

        Hi Reiner
        If you manage to get a sample Windows form login created, can you please include a VB version ….
        
        Thanks

        FYI, I have just installed application fix package 22 to our 4.7 version and I started getting calls from my users saying the VB SAP.Connect program didn’t work. As no changes had been made recently I thought it was one of those user things…
        
        But guess what – it wasn’t. The RFC I used in my program and the one used in all the demos (RFC_Customer_Get) does not exist any more. So now until I can work out the most appropriate BAPI and if it passes across the same data etc, I’ve had to comment out the direct SAP links and put it back to data entry by the user.
        
        Not impressive from SAP

  Expand the BOR node in Server Explorer, search or browse to your BOR class and drag it (the class icon) to your .sapwsdl designer.
  
  PS: Please post this kind of questions to the forum, not to the WebLog in future.
