Connect to SAP Data from PowerBuilder

This article demonstrates how to access SAP data from PowerBuilder using the CData ADO.NET Provider for SAP.

The CData ADO.NET providers are easy-to-use, standards-based controls that can be used from any platform or development technology that supports Microsoft .NET, including PowerBuilder. This article shows how to use the CData ADO.NET Provider for SAP in PowerBuilder.

This article shows how to create a basic PowerBuilder application that uses the CData ADO.NET Provider for SAP to retrieve data.

  1. In a new WPF Window Application solution, add all the Visual Controls needed for the connection properties. Below is a typical connection string:

    Host=sap.mydomain.com;User=EXT90033;Password=xxx;Client=800;System Number=09;ConnectionType=Classic;Location=C:\\mysapschemafolder;

    You can connect to SAP systems using either librfc32.dll, librfc32u.dll, NetWeaver, or Web Services (SOAP). Set the ConnectionType connection property to CLASSIC (librfc32.dll), CLASSIC_UNICODE (librfc32u.dll), NETWEAVER, or SOAP.

    If you are using the SOAP interface, set the Client, RFCUrl, SystemNumber, User, and Password properties, under the Authentication section.

    Otherwise, set Host, User, Password, Client, and SystemNumber.

    Note: We do not distribute the librfc32.dll or other SAP assemblies. You must find them from your SAP installation and install them on your machine.

    For more information, see this guide on obtaining the connection properties needed to connect to any SAP system.

  2. Add the DataGrid control from the .NET controls.
  3. Configure the columns of the DataGrid control. Below are several columns from the Account table: <DataGrid AutoGenerateColumns="False" Margin="13,249,12,14" Name="datagrid1" TabIndex="70" ItemsSource="{Binding}"> <DataGrid.Columns> <DataGridTextColumn x:Name="idColumn" Binding="{Binding Path=MANDT}" Header="MANDT" Width="SizeToHeader" /> <DataGridTextColumn x:Name="nameColumn" Binding="{Binding Path=MANDT}" Header="MANDT" Width="SizeToHeader" /> ... </DataGrid.Columns> </DataGrid>
  4. Add a reference to the CData ADO.NET Provider for SAP assembly.

Connect the DataGrid

Once the visual elements have been configured, you can use standard ADO.NET objects like Connection, Command, and DataAdapter to populate a DataTable with the results of an SQL query:

System.Data.CData.SAPERP.SAPERPConnection conn conn = create System.Data.CData.SAPERP.SAPERPConnection(connectionString) System.Data.CData.SAPERP.SAPERPCommand comm comm = create System.Data.CData.SAPERP.SAPERPCommand(command, conn) System.Data.DataTable table table = create System.Data.DataTable System.Data.CData.SAPERP.SAPERPDataAdapter dataAdapter dataAdapter = create System.Data.CData.SAPERP.SAPERPDataAdapter(comm) dataAdapter.Fill(table) datagrid1.ItemsSource=table.DefaultView

The code above can be used to bind data from the specified query to the DataGrid.
