ABAP to .NET

[Former Member]

Hello Experts,

Is there a way to call a .NET application from ABAP?

Acually this .Net application perfoms a specific process and generates some XML files and put them in a folder. I should trigger that .Net application to do that process from a button in SAP. so I need a way or a solution on how to trigger that .NET application to do that procedure. the .NET application can be adapted accordingly.

Any ideas please?

Hi ,

You can call .net application( it should be as exe file) from abap by using FM "WS_EXECUTE".

Hello Nehruu,

I think you are saying that I shall make the .NET application executable through an exe and then I execute this file using WS_EXECUTE command from ABAP and this will do the job.

your answer is of a great value, thanks a lot. I think this will solve the problem. will revert back if I have any raised issue after I implement the solution.

Thanks again

sorry forgot to ask you, can I use this command to run that exe on a remote computer? the .NET application will not be aside the SAP server but on another computer.

can I use this function to call an exe program on another computer?

Thanks

set the thread as un-answered because I posted another question.

First, you shouldn't use WS_EXECUTE. Instead you should use the method EXECUTE, of the class CL_GUI_FRONTEND_SERVICES. This allows you to execute a program on the presentation layer, the local PC where the SAPgui is installed, or I think you may be able to execute a program which resides on a shared folder on remote network server.

Hi,

If the .net application runs on a service, you should :

1. create a web service in .net that allows executing of the program

2. on the abap side, call that web service (using the wizzard) when you click on that button.

Hello Wouter,

The customer don't want to go for a web-service approach. is there a way that we define a listening port in the .NET and I connect to that port via ABAP? how can I do this, any step by step tutorial?

Hi,

in .NET, you can easily listen to TCP-Ports. Please have a look at the System.Net.Sockets namespace in .NET, there you find the TCPListener class. For programming example, see http://www.eggheadcafe.com/articles/20020323.asp

In SAP, I think you have to create a RFC destination, please see this thread [creating TCP/IP connection using RFC in SM59|]

Hope it helps.

Hello all, there was a decision to follow the exe execution. Thanks indeed
