Back Up SAP Netweaver Gateway data to SQL Server through SSIS

This article illustrates using the SAP Netweaver Gateway ADO.NET Data Provider within a SQL Server SSIS workflow for the direct transfer of SAP Netweaver Gateway data to a Microsoft SQL Server database. It's worth noting that the identical process detailed below is applicable to any CData ADO.NET Data Providers, enabling the direct connection of SQL Server with remote data through SSIS.

1. Open Visual Studio and create a new Integration Services project.
2. Add a new Data Flow task from the toolbox onto the Control Flow screen.

3. In the Data Flow screen, add an ADO.NET Source and an OLE DB Destination from the toolbox.

4. Add a new connection and select .NET Providers\CData ADO.NET Provider for SAP Netweaver Gateway.

5. In the connection manager, enter the connection details for SAP Netweaver Gateway data.

   SAP Gateway allows both basic and OAuth 2.0 authentication. You can use basic authentication to connect to your own account, or you can use OAuth to enable other users to retrieve data from your service with their accounts. In addition to authenticating, set the following connection properties to access SAP Gateway tables.

   • Url: Set this to the URL of your environment, or to the full URL of the service. For example, the full URL might appear as: https://sapes5.sapdevcenter.com/sap/opu/odata/IWBEP/GWSAMPLE_BASIC/. In this example, the environment URL would just be: https://sapes5.sapdevcenter.com.
   • Namespace: Set the appropriate Service Namespace. In the example above, IWBEP is the namespace. It is optional if the full URL to the service is specified.
   • Service: Set this to the service you want to retrieve data from. In the example above, the service is GWSAMPLE_BASIC. It is not required if the full URL is specified.

   Authenticate via Basic Authentication

   In basic authentication, you use your login credentials to connect. Set the following properties:

   • User: This is the username you use to log in to SAP Gateway.
   • Password: This is the password you use to log in to SAP Gateway.

   Authenticate via OAuth Authentication

   You can connect to SAP Gateway using the embedded OAuth connectivity (without setting any additional authentication connection properties). When you connect, the OAuth endpoint opens in your browser. Log in and grant permissions to complete the OAuth process. See the OAuth section in the online Help documentation for more information on other OAuth authentication flows.

6. Open the DataReader editor and set the following information:

   • ADO.NET connection manager: In the Connection Managers menu, select the Data Connection you just created.
   • Data access mode: Select 'SQL command'.
   • SQL command text: In the DataReader Source editor, open the Component Properties tab and enter a SELECT command, such as the one below:
     SELECT ProductID, Quantity FROM SalesOrderLineItems WHERE Quantity < 15

7. Close the DataReader editor and drag the arrow below the DataReader Source to connect it to the OLE DB Destination.

8. Open the OLE DB Destination and enter the following information in the Destination Component Editor.

   • Connection manager: Add a new connection. Enter your server and database information here. In this example, SQLExpress is running on a separate machine.
   • Data access mode: Set your data access mode to "table or view" and select the table or view to populate in your database.

9. Configure any properties you wish on the Mappings screen.

10. Close the OLE DB Destination Editor and run the project. After the SSIS task has finished executing, your database will be populated with data obtained from SAP Netweaver Gateway data.
