Analyze SAP HANA Data in Infragistics Reveal

Reveal is a data visualization solution provided by Infragistics and can be paired with the CData API Server to build dynamic dashboards from live SAP HANA data. The CData API Server generates an OData API for SAP HANA, which is natively consumable in Reveal. In this article, we walk through connecting to SAP HANA in API Server and connecting to the API Server from Infragistics Reveal to create a simple dashboard.

Connect to SAP HANA from API Server

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

1. Open API Server and click Settings -> Connection -> Add Connection 👁 Adding a connection
   
2. Select "SAP HANA" 👁 Selecting a Connector (Salesforce is shown).
   
3. Enter the necessary authentication properties to connect to SAP HANA.

   Set the Server, Database and Port properties to specify the address of your SAP Hana database to interact with. Set the User and the Password properties to authenticate to the server. 👁 Configuring a connection (Salesforce is shown).
   

Add SAP HANA Resource Definitions in API Server

After connecting to SAP HANA, create Resources, which represent API endpoints for SAP HANA data.

1. Click Settings -> Resources -> Add Resource 👁 Adding a new resource
   
2. Select the SAP HANA connection 👁 Selecting a connection (Salesforce is shown)
   
3. Select the table you wish to retrieve and click Next 👁 Selecting a Table (Salesforce is shown)
   
4. (Optional) Edit the resource to select specific fields and more
5. Save the settings

Add an API Server User

Create a User to connect to SAP HANA from Reveal through API Server.

1. Click Settings -> Users
2. Click Add
3. Configure a User with access to the SAP HANA Connection and Resource(s) 👁 Creating a new user
   

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

When accessing and connecting to multiple different 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 Settings -> Server.

• 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.

With the API Server configured, we can visualize SAP HANA data in Reveal.

1. Log into Reveal and click Dashboards -> New 👁 Adding a new dashboard
   
2. Click Data Source -> OData Feed 👁 Adding a new OData data source
   
3. Specify the API Server API endpoint URL, for example: https://serverurl/api.rsc 👁 Configuring the OData URL
