Access Live SAP Netweaver Gateway Data in SAS JMP via ODBC

You can use the CData ODBC Driver for SAP Netweaver Gateway to integrate live data into your statistical analysis with SAS JMP. The driver proxies your queries directly to the SAP Netweaver Gateway API, ensuring that your analysis reflects any changes to the data. The CData ODBC Driver supports the standard SQL used by JMP in the background as you design reports.

The SAP Netweaver Gateway API supports bidirectional access. This article shows how to access SAP Netweaver Gateway data into a report and create data visualization. It also shows how to use SQL to query and manipulate SAP Netweaver Gateway data from the JMP Query Builder.

Access SAP Netweaver Gateway Data 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.

Import SAP Netweaver Gateway Data with the Query Builder

After you have created the SAP Netweaver Gateway DSN, you can use SQL to invoke the capabilities of the SAP Netweaver Gateway API. Follow the steps below to execute some supported queries in the Query Builder:

1. In SAS JMP, click File -> Database -> Query Builder. The Select Database Connection dialog is displayed.
2. Click New Connection.
3. On the Machine Data Source tab, select the ODBC DSN you configured and then click Next. 👁 Select the ODBC DSN you configured. (Salesforce is shown.)
   
4. The Select Tables for Query dialog is displayed and in the Available Tables section, select a table and click Primary. After choosing the primary table, click Build Query to open the Query Builder. 👁 Select the Primary table for the Query. (Salesforce is shown.)
   
5. As you drag Available Columns to the Included Columns tab, the underlying SQL query is updated and you can view the generated SQL Query in the SQL tab. 👁 The generated query in the Query Builder. (Salesforce is shown.)
   
6. Click Run Query to display the data. 👁 The results of a query in the Query Builder. (Salesforce is shown.)
   
7. To refresh the results with the current data, right-click Update from Database and click Run Script.

Manipulate SAP Netweaver Gateway Data

You can execute data manipulation queries from JSL scripts such as the one below. To execute a script, click New Script in the toolbar. To connect, specify the DSN. You can then use the standard SQL syntax:

Open Database( "DSN=CData SAPGateway Source;",
"INSERT INTO SalesOrderLineItems
(Quantity)
VALUES ('15');");

Visualize SAP Netweaver Gateway Data

After importing, you can use the Graph Builder to create graphs visually. To open the Graph Builder, click the Graph Builder button in the toolbar.

1. Drag a dimension column onto the x axis. For example, ProductID.
2. Drag a measure column onto the y axis. For example, Quantity.
3. Select a chart type. For example, a bar chart. 👁 Configuration of a basic chart. (Salesforce is shown.)
