Visualize SAP Netweaver Gateway Data in Tableau

The CData ODBC driver for SAP Netweaver Gateway enables you integrate SAP Netweaver Gateway data into Tableau dashboards.

The CData ODBC Driver for SAP Netweaver Gateway enables you to access live SAP Netweaver Gateway data in business intelligence tools like Tableau. In this article, you will integrate SAP Netweaver Gateway data into a dashboard that reflects changes to SAP Netweaver Gateway data in real time.

The CData ODBC drivers offer unmatched performance for interacting with live SAP Netweaver Gateway data in Tableau due to optimized data processing built into the driver. When you issue complex SQL queries from Tableau to SAP Netweaver Gateway, the driver pushes supported SQL operations, like filters and aggregations, directly to SAP Netweaver Gateway and utilizes the embedded SQL engine to process unsupported operations (often SQL functions and JOIN operations) client-side. With built-in dynamic metadata querying, you can visualize and analyze SAP Netweaver Gateway data using native Tableau data types.

Connect to SAP Netweaver Gateway as an ODBC Data Source

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

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.

When you configure the DSN, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

Add SAP Netweaver Gateway Data to a Dashboard

  1. Click Connect to Data -> More Servers -> Other Databases (ODBC).
    Select the CData Data Source Name (for example: CData SAPGateway Source).
  2. In the Database menu, select CData.
  3. In the Table box, enter a table name or click New Custom SQL to enter an SQL query. This article retrieves the SalesOrderLineItems table.
  4. Drag the table onto the join area. At this point, you can include multiple tables, leveraging the built-in SQL engine to process complex data requests.
  5. In the Connection menu, select the Live option, so that you skip loading a copy of the data into Tableau and instead work on real-time data. The optimized data processing native to CData ODBC drivers enables unmatched performance in live connectivity.
  6. Click the tab for your worksheet. Columns are listed as Dimensions and Measures, depending on the data type. The CData driver discovers data types automatically, allowing you to leverage the powerful data processing and visualization features of Tableau.
  7. Drop the ProductID column in the Dimensions pane onto the dashboard. When you select dimensions, Tableau builds a query to the driver. The results are grouped based on that dimension. In Tableau, the raw query is automatically modified as you select dimensions and measures.
  8. Drag the Quantity column in the Measures field onto the Detail and Color buttons. Tableau executes the following query:

    SELECT ProductID, SUM(Quantity) FROM SalesOrderLineItems GROUP BY ProductID

    When you select a measure, Tableau executes a command to the driver to calculate a summary function, such as SUM, AVG, etc., on the grouped values. The SQL engine (embedded within the driver) is leveraged to process the aggregation of the data, where needed, providing a seamless experience in Tableau, regardless of the data source.

    To change the summary function, open the Quantity menu and select the summary you want in the Measure command.

  9. You can create other charts using dimensions and measures to build SQL queries visually:

With the CData ODBC Driver for SAP Netweaver Gateway, you get live connectivity to your SAP Netweaver Gateway data, allowing you to build real-time charts, graphs, and more.
