Visualize SAP Netweaver Gateway Data in TIBCO Spotfire through OData

OData is a major protocol enabling real-time communication among cloud-based, mobile, and other online applications. The CData Connect Server provides SAP Netweaver Gateway data to OData consumers like TIBCO Spotfire. This article shows how to use the Connect Server and Spotfire's built-in support for OData to access SAP Netweaver Gateway data in real time.

Configuring Connect Server

To work with live SAP Netweaver Gateway data in TIBCO Spotfire, we need to connect to SAP Netweaver Gateway from Connect Server, provide user access to the new virtual database, and create OData endpoints for the SAP Netweaver Gateway data.

Add a Connect Server User

Create a User to connect to SAP Netweaver Gateway from TIBCO Spotfire through Connect Server.

1. Click Users -> Add
2. Configure a User
3. Click Save Changes and make note of the Authtoken for the new user

Connect to SAP Netweaver Gateway from Connect Server

CData Connect Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

1. Open Connect Server and click Connections
2. Select "SAP Netweaver Gateway" from Available Data Sources
3. Enter the necessary authentication properties to connect to SAP Netweaver Gateway.

   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.

4. Click Save Changes
5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions (SELECT is all that is required for Reveal).

Add SAP Netweaver Gateway OData Endpoints in Connect Server

After connecting to SAP Netweaver Gateway, create OData Endpoints for the desired table(s).

1. Click OData -> Tables -> Add Tables
2. Select the SAP Netweaver Gateway database
3. Select the table(s) you wish to work with and click Next
4. (Optional) Edit the resource to select specific fields and more
5. Save the settings

(Optional) Configure Cross-Origin Resource Sharing (CORS)

When accessing and connecting to multiple domains from an application such as Ajax, there is a possibility of violating the limitations of cross-site scripting. In that case, configure the CORS settings in OData -> Settings.

• Enable cross-origin resource sharing (CORS): ON
• Allow all domains without '*': ON
• Access-Control-Allow-Methods: GET, PUT, POST, OPTIONS
• Access-Control-Allow-Headers: Authorization

Save the changes to the settings.

Create Data Visualizations on External SAP Netweaver Gateway Data

1. Open Spotfire and click Data -> Add data...
2. Then, click "Connect to" -> OData -> New Connection. In the OData Connection dialog, enter the following information:
   • Service URL: Enter the Connect Server's OData endpoint. For example: http://localhost:8080/odata.rsc
   • Authentication Method: Select Username and Password.
   • Username: Enter the username of a Connect Server user. You can create API users on the Security tab of the administration console.
   • Password: Enter the authtoken of a Connect Server user.
3. Select the tables and columns you want to add to the dashboard. This example uses SalesOrderLineItems.

4. If you want to work with the live data, click the Keep Data Table External option. This option enables your dashboards to reflect changes to the data in real time.

   If you want to load the data into memory and process the data locally, click the Import Data Table option. This option is better for offline use or if a slow network connection is making your dashboard less interactive.

5. After you have selected a table, Spotfire uses the data to detect number, time, and other categories. You are now on your way to creating new visualizations for analytics, reporting, and more.
