Visualize Live SAS Data Sets Data in the Power BI Service

Power BI transforms your company's data into rich visuals for you to collect and organize so you can focus on what matters to you. When paired with CData Connect AI, you get instant access to SAS Data Sets data for visualizations, dashboards, and more. This article shows how to build and publish a dataset from SAS Data Sets data in Power BI and then create reports on SAS Data Sets data in the Power BI service.

CData Connect AI provides a pure SQL interface for SAS Data Sets, allowing you to easily build reports from live SAS Data Sets data in Power BI — with no need to replicate the data. As you build visualizations, Power BI generates SQL queries to gather data. Using optimized data processing out of the box, CData Connect AI pushes all supported SQL operations (filters, JOINs, etc) directly to SAS Data Sets, leveraging server-side processing to quickly return SAS Data Sets data.

NOTE: You can also import SAS Data Sets data into Power BI through Connect AI (instead of using the on-premise gateway). Read how in the related Knowledge Base article.

Configure SAS Data Sets Connectivity for Power BI

Connectivity to SAS Data Sets from Power BI is made possible through CData Connect AI. To work with SAS Data Sets data from Power BI, we start by creating and configuring a SAS Data Sets connection.

1. Log into Connect AI, click Sources, and then click Add Connection

2. Select "SAS Data Sets" from the Add Connection panel

3. Enter the necessary authentication properties to connect to SAS Data Sets.

   Set the following connection properties to connect to your SAS DataSet files:

   Connecting to Local Files

   • Set the Connection Type to "Local." Local files support SELECT, INSERT, and DELETE commands.
   • Set the URI to a folder containing SAS files, e.g. C:\PATH\TO\FOLDER\.

   Connecting to Cloud-Hosted SAS DataSet Files

   While the driver is capable of pulling data from SAS DataSet files hosted on a variety of cloud data stores, INSERT, UPDATE, and DELETE are not supported outside of local files in this driver.

   Set the Connection Type to the service hosting your SAS DataSet files. A unique prefix at the beginning of the URI connection property is used to identify the cloud data store and the remainder of the path is a relative path to the desired folder (one table per file) or single file (a single table). For more information, refer to the Getting Started section of the Help documentation.

   
4. Click Save & Test
5. Navigate to the Permissions tab in the Add SAS Data Sets Connection page and update the User-based permissions.

Add a Personal Access Token

When connecting to Connect AI through the REST API, the OData API, or the Virtual SQL Server, a Personal Access Token (PAT) is used to authenticate the connection to Connect AI. It is best practice to create a separate PAT for each service to maintain granularity of access.

1. Click on the Gear icon () at the top right of the Connect AI app to open the settings page.
2. On the Settings page, go to the Access Tokens section and click Create PAT.
3. Give the PAT a name and click Create.
4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

With the connection configured and a PAT generated, you are ready to connect to SAS Data Sets data from Power BI.

Connecting to Connect AI from Power BI

To connect to and visualize live SAS Data Sets data in the Power BI service, install the on-premise data gateway, add a data source to the gateway from the Power BI service, and publish a dataset from Power BI Desktop to the service.

Install the On-Premises Data Gateway

The Microsoft on-premise data gateway provides secure data transfer between connected data sources and various cloud-based Microsoft tools and platforms. You can read more about the gateway in the Microsoft documentation.

You can download and install the gateway from the Power BI service:

1. Log in to PowerBI.com.
2. Click the Download menu and click Data Gateway.
3. Follow the instructions for installation, making note of the name of the gateway.

Add SAS Data Sets as a Data Source to the Power BI Service

Once you have installed the data gateway, you add Connect AI as a data source to the Power BI service:

1. Log in to PowerBI.com.
2. Click the Settings menu and click "Manage gateways."
3. Click "ADD DATA SOURCE" and configure the connection to Connect AI:
   
   
   • Set Data Source Name to something like ConnectCloudSASDataSets.
   • Choose SQL Server as the Data Source Type.
   • Set Server to tds.cdata.com,14333.
   • Set Database to the name of your SAS Data Sets connection (e.g. SASDataSets1).
   • Set Authentication Method to Basic.
   • Set Username to a Connect AI user (e.g. [email protected])
   • Set Password to the PAT for the user above.

Publish a Dataset from Power BI Desktop

With the gateway installed and Connect AI added as a datasource to the Power BI service, you can publish a dataset from Power BI Desktop to the service.

1. Open Power BI, click Get Data -> More, then select SQL Server database, and click Connect.

2. Set the connection properties and click OK.
   • Set Server to tds.cdata.com,14333.
   • Set Database to the name of your SAS Data Sets connection (e.g. SASDataSets1).
   • Set Data Connectivity mode to DirectQuery*.
   * DirectQuery enables live query processing and real-time visualizations of SAS Data Sets data.
3. In the authentication wizard, select Database, set the User name and Password properties, and click Connect.

4. Select the table(s) to visualize in the Navigator dialog.
5. In the Query Editor, you can customize your dataset by filtering, sorting, and summarizing SAS Data Sets columns. Click Edit to open the query editor. Right-click a raw to filter the rows. Right-click a column header to perform options like the following:
   • Change column data types
   • Remove a column
   • Group by columns

   Power BI detects each column's data type from the SAS Data Sets metadata reported by Connect AI.

   Power BI records your modifications to the query in the Applied Steps section, adjusting the underlying data retrieval query that is executed to the remote SAS Data Sets data. When you click Close and Apply, Power BI executes the data Retrieval query.

   Otherwise, click Load to pull the data into Power BI.

6. Define any relationships between the selected entities on the Relationships tab.
7. Click Publish (from the Home menu) and select a Workspace.

Build Reports and Dashboards on SAS Data Sets Data in the Power BI Service

Now that you have published a dataset to the Power BI service, you can create new reports and dashboards based on the published data:

1. Log in to PowerBI.com.
2. Click Workspaces and select a workspace.
3. Click Create and select Report.
4. Select the published dataset for the report.
5. Choose fields and visualizations to add to your report.

Live Access to SAS Data Sets Data from Cloud Applications

Now you have a direct connection to live SAS Data Sets data from the Power BI service. You can create more data sources and new visualizations, build reports, and more — all without replicating SAS Data Sets data.
