Using the code

First install ERPConnect in the dev environment. After installing ERPConnect, goto Add References block in the application, locate the ERPConnect.dll and hit add.Once the ERPConnect.dll is added to the reference folder. you can add following to the xyz.cs file Now its all upto you. You can implement as you wish.In the code belo I am using the concept of Special Classes.

Block of code :

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Data.Odbc;
using ERPConnect;
using ERPConnect.Utils;
using ERPConnect.Queries;
 
namespace SAP1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
try
{
//licence
   ERPConnect.LIC.SetLic(); //Not Required in case of trial version but is must in case of licenced version

//creating the connection object
R3Connection con = new R3Connection("SAP Server IP/Name", System Number, "UserName", "PWDl", "Language", "Client");

//open the connection
con.Open();

DataTable dt = new DataTable();
ReadTable rt = new ReadTable(con);

rt.TableName = "SAP Table Name";
rt.AddField("FieldName");
rt.AddField("FieldName");


rt.Run();
dt = rt.Result;
dataGridView1.DataSource = dt; // displays the result in gridview
}
catch (Exception ex)
{
 textBox1.Text = ex.Message;
}

}
}
