The following sample shows how to use the ReadTable class to read data from an SAP table and how to process the ADO.NET result table object.

Read Data From Tables

Follow the steps below to read tables from SAP:

  1. Connect to the SAP system using R3Connection.
  2. Create a table object using ReadTable().
  3. Specify the name of the SAP table using TableName.
  4. Specify the columns you want to read using AddField().
  5. Optional: Specify additional parameters, e.g., WHERE Clause (WhereClause or maximum number of rows RowCount).
  6. Read the SAP table using Run().
  7. Access the table using the Result attribute.

// Open the connection to SAP
using var connection = new R3Connection(
    host: "server.acme.org",
    systemNumber: 00,
    userName: "user",
    password: "passwd",
    language: "EN",
    client: "001")
{
    Protocol = ClientProtocol.NWRFC,
};

connection.Open();

var table = new ReadTable(connection)
{
    WhereClause = "SPRAS = 'EN'",
    TableName = "MAKT",
    RowCount = 10
};

// Select columns to read
table.AddField("MATNR");
table.AddField("MAKTX");

table.Run();

DataTable result = table.Result;
for (int i = 0; i < result.Rows.Count; i++)
{
    Console.WriteLine($"{result.Rows[i]["MATNR"]} {result.Rows[i]["MAKTX"]}");
}

Console.ReadLine();
