Simply Application-to-Application Sample

[Former Member]

Hello,

I want to create an SAP Object from our external application. I want to fill out some data in this object and then display the SAP GUI containing the created object. The code in our application can be written in C# or C++.

What is the simpliest way to do this?

Which technology should i use?

Where can i find an example?

Which documentation should i use?

Thanks for every response

This is exactly what i want.

I want to start the R3 transaction within my C#/C++ code and then i want to view this transaction in the GUI and so the user can complete the transaction.

How do i start the transaction? Should i create a Web Service in R3? How do i do that?

Thanks Gerhard

Hi Gerhard,

You need to create a iView for that transcation and the same need to deployed in the portal. On requesting the URL thru HTTP request you will be able view the transcation in the IE.

I would advies you to post this query in Portal forum so that you will get a perfect and valuable answer rather than posting it in a XI forum. Or do search for a blog in Portal section you will find many.

Thanks for your answer.

I want to open SAP Gui screen with IE (so i want to use the WebGui from SAP).

yes, i will research for creating the object using a HTTP request.

Is there any example? I work the first time with SAP - so it's not so easy for me doing that.

Thanks, Gerhard

Hi,

<i>

>>> want to open SAP Gui screen with IE (so i want to use the WebGui from SAP).</i>

This is what is the functionality of EP. There is no need to any extra application to be written in C++/C#. SAP Comes with Web Application Server and you just need to use the Portal functionality. You can use WebDynpro to develop screen or you can show the existing R/3 transcation in IE with out any other 3rd party application.

Hi,

There are many ways you can achieve this, but please confirm that do you need to display SAP GUI screen in the application developed using C+/C#. Or you will have your own GUI and need to get the data from SAP. OR You are tying to post some data into R/3 using C+/C# and you need to see that created object by logging into SAP GUI.

1.If you are interested in creating some object (eg; sales order) in R/3you can use XI using IDOC or BAPI in the receiver side. From your C++/C# application you can send data either by HTTP request/SOAP Request/Save a File in some folder.

2. If you are interested in retriving data from R/3 you can always go for HTTP request/SOAP Request

3. Even if you are not at all intersted in XI the go for RFC call from the External system I mean using C++/C# with the help of librfc32.dll

The simplest way is to doing a HTTP request to XI form the C++/C# application.
