Build an RFC Client with NCo 3.0 for VB.NET – A Step-By-Step Guide

November 8, 2011 By 1 Comment

Recently, I published an article showing step-by-step instructions for how to consume an SAP RFC with the SAP .Net Connector 3.0 (NCo 3.0).  The article included code samples and a working code example for download written in C#.  Well, not everybody writes in C#.  There are some of you that would prefer to write in VB.NET.  So, I have heeded your call, all you VB.NET developers!  Here is your very own article detailing how to build an RFC client with NCo 3.0 for VB.NET.

The SAP .Net Connector 3.0 (NCo 3.0) offers many improvements over SAP .NET Connector 2.0. Unfortunately, SAP no longer offers example .NET code.  This blog attempts to fill that gap by describing how to build a simple RFC Client using SAP .Net Connector (NCo) 3.0 with VB.NET.  Click here to request a .zip file containing a copy of the source code.

NCo 3.0: Reconnecting a Broken RFC Server Connection

September 21, 2011 By Leave a Comment

Don’t you hate it when you’re talking on the cell phone and the call drops?   I was talking to my wife on the way to my client site this week and was telling her about this awesome blog post I was writing when the call dropped.  Bummer.  Since I really wanted to tell her about my blog, I wanted to complete the conversation.  But first, I had to wait for service.  Then I had to call her back, and have her answer.  Then I uttered the phrase that all cell phone users know, “What was the last thing you heard me say?”  It was a fairly messy recovery, but I was finally able to talk about my blog!

When two software systems integrate, we also have to deal with the “dropped call” problem.  SAP NCo 3.0 offers a few different levels of  data recovery options depending on whether NCo is the client or the server.  But before any data recovery can happen, the first step is to call the other party back.  This blog post describes the general process to reconnect an NCo RfcServer to an SAP gateway host.

Build an RFC Server with NCo 3.0 – A Step-By-Step Guide

August 23, 2011 By 3 Comments

 

SAP .NET Connector 2.0 offered a couple of different sample projects that were instrumental in my learning process.  As I mentioned in my post detailing the steps to build an RFC client, SAP no longer supplies code samples with SAP .NET Connector (NCo) 3.0.  So, I decided to make available some code examples created by my colleague, Terry DeBruicker.

This blog describes how to build a simple RFC Server using the SAP NCo 3.0. The sample program implements RFC STFC_CONNECTION.  STFC_CONNECTION is a good example to use because it contains both importing and exporting parameters.

Build an RFC Client with NCo 3.0 – A Step-By-Step Guide

August 16, 2011 By 9 Comments

The SAP .Net Connector 3.0 (NCo 3.0) offers many improvements over the 2.0 version of that product. Unfortunately, SAP no longer offers example .NET code.  This blog attempts to fill that gap by describing how to build a simple RFC Client using SAP .Net Connector (NCo) 3.0.  Click here to request a .zip file containing a copy of the source code.

The sample program displays details about companies defined by SAP. There are two BAPI calls involved, BAPI_COMPANY_GETLIST and BAPI_COMPANY_GETDETAIL.
Along with the SAP .Net Connector 3.0, we are using Microsoft Visual Studio 2010 and the Microsoft .Net Framework 4.0 to build our sample.  Prior to starting, you will have to download and install NCo 3.0 (OSS login required).

Introducing SAP .NET Connector (NCo) 3.0

January 5, 2011 By 6 Comments

This past summer, SAP announced a new version of SAP Connector for Microsoft .NET — NCo 3.0.  SAP decided to give us an early Christmas present when they officially released NCo 3.0 on December 22, 2010.  You can download NCo 3.0 at http://service.sap.com/connectors (you will need an OSS logon).

Included in the downloads are documents that discuss the notable changes from .NET Connector 2.0 and a very comprehensive help file (in .chm format).  Noticeably absent are complete samples, although SAP claims that the included tutorial will be updated.

Additionally, I already have my first NCo 3.0 project under way, so check back soon for more information about NCo 3.0!

Happy Coding!

[UPDATED]

Coming Soon: SAP .NET Connector (NCo) 3.0

July 21, 2010 By 8 Comments

SAP is announcing a new version of SAP Connector for Microsoft .NET 3.0 (now called “NCo 3.0″). A beta program for selected customers and partners is currently underway (Q3, 2010) with the general release of the software coming soon thereafter.  I will highlight some of the major differences between the SAP Connector for Microsoft .NET 2.0 and NCo 3.0 (besides the obvious, and much-needed name-shortening).

EDITOR’S NOTE: NCo 3.0 has now been released.  Read more details here.

Build an SAP RFC Server using the SAP .Net Connector

March 9, 2010 By 1 Comment

This blog post describes step-by-step how to use the SAP .Net Connector and Microsoft C# to create an SAP RFC Server. This allows an SAP process to call your custom C# code, which can accept parameters and return values.

The SAP .Net Connector simplifies creating C# programs that can interoperate with an SAP host. The SAP .Net Connector is available from the SAP Service Marketplace. You must have access to the SAP Service Marketplace to be able to download the SAP .Net Connector. The SAP .Net Connector must be installed on your development machine before we begin.

RFC is a Remote Function Call. In this case, the SAP process is a ‘client’ that is making an RFC call to our custom ‘server’ code. Our code uses the SAP .Net Connector to register on an SAP Application Gateway.

The TLA system we have been creating exists solely to demonstrate certain programming techniques involving the SAP .Net Connector and C#.  We will cover three separate parts of the solution: defining the function to SAP, creating a proxy object used to access SAP, and creating our C# code to perform the RFC function.

Build an SAP IDOC Receiver Using the SAP .Net Connector

December 16, 2009 By 1 Comment

Overview

This blog post describes how to receive an IDOC from an SAP system, using the SAP .Net Connector and Microsoft C#.

Introduction

The SAP .Net Connector simplifies creating C# programs that can interoperate with an SAP host. The SAP .Net Connector is available from the SAP Service Marketplace. You must have access to the SAP Service Marketplace to be able to download the SAP .Net Connector. The SAP .Net Connector must be installed on your development machine before we begin.

An IDOC is an Interface Document that is used to send or receive information to or from an SAP host.  An IDOC will consist of a header record and as many detail records as necessary. The header records follow the format of the EDI_DC40 table, and the detail records follow the format of the EDI_DD40 table. The exact format of the payload in the detail records depends on the type of IDOC being transmitted.
