Good Day!

One of the projects that I need to deliver in my internship is to automate a transaction in SAP GUI(specifically under the financials module). Is it possible to automate a transaction by using c#, if yes what would be the steps for connecting c# to SAP GUI?

Thanks!

Solution 2

For those who want to Automate the SAP GUI and are only able to do so through VBA and VB.Net. Here is a simple solution to automate SAP using C#:

First add two references:
SAPFEWSELib
SapROTWr <---- This one is located in the folder where SAP was installed.

Then add the using statements:

using SAPFEWSELib;
using SapROTWr;


Once those are added, add the following to a button:

//Get the Windows Running Object Table
SapROTWr.CSapROTWrapper sapROTWrapper = new SapROTWr.CSapROTWrapper();
//Get the ROT Entry for the SAP Gui to connect to the COM
object SapGuilRot = sapROTWrapper.GetROTEntry("SAPGUI");
//Get the reference to the Scripting Engine
object engine = SapGuilRot.GetType().InvokeMember("GetScriptingEngine", System.Reflection.BindingFlags.InvokeMethod, null, SapGuilRot, null);
//Get the reference to the running SAP Application Window
GuiApplication GuiApp = (GuiApplication)engine;
//Get the reference to the first open connection
GuiConnection connection = (GuiConnection)GuiApp.Connections.ElementAt(0);
//get the first available session
GuiSession session = (GuiSession)connection.Children.ElementAt(0);
//Get the reference to the main "Frame" in which to send virtual key commands
GuiFrameWindow frame = (GuiFrameWindow)session.FindById("wnd[0]");



This example works exactly like the Visual Basic Version does.


If you want to enter text into a text field within SAP, you must explicitly cast the object into the correct variable type

an example of entering an order number into CO02 Transaction, would be:

GuiTextField ordNum = (GuiTextField)session.FindById("wnd[0]/usr/ctxtCAUFVD-AUFNR");
ordNum.Text = textBox1.Text;
frame.SendVKey(0);

Don't drop a new answer on an old question (this one is a year and half old!). If you've got something useful like this, write up a tip/trick or even an article if you can go into enough detail about the how's and why's.

Dave, you are absolutely right, I should. The problem is, this search came up as one of the top google searches, and since I have successfully found a way to establish a COM reference to SAP, I thought I would share this since there is close to nothing out there except for people who may have access to the .Net connector; which I do not. So, I am sorry for posting this on such an old post, but thought it may be useful for someone who stumbled upon it themselves. Or at least a solid answer for historical purposes. Thanks for your feedback though

-> The server threw an exception. (Exception from HRESULT: 0x80010105 (RPC_E_SERVERFAULT)). Please me to solve the error

You can't connect to GUI. You can connect with SAP data.
Please, see my past answer[^].

In Visual Studio, open a NuGet Package Manager Console and type the following:

Install-Package SAP.GUI.Scripting.net -Version 1.0.0

That will install the DLLS on your current solution. Hope this helps.
