How to Create Power BI Visual Reports with Real-Time SAS Data Sets Data

CData Power BI Connectors provide self-service integration with Microsoft Power BI. The CData Power BI Connector for SAS Data Sets links your Power BI reports to real-time SAS Data Sets data. You can monitor SAS Data Sets data through dashboards and ensure that your analysis reflects SAS Data Sets data in real time by scheduling refreshes or refreshing on demand. This article details how to use the Power BI Connector to create real-time visualizations of SAS Data Sets data in Microsoft Power BI Desktop.

Collaborative Query Processing

The CData Power BI Connectors offer unmatched performance for interacting with live SAS Data Sets data in Power BI due to optimized data processing built into the connector. When you issue complex SQL queries from Power BI to SAS Data Sets, the connector pushes supported SQL operations, like filters and aggregations, directly to SAS Data Sets 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 SAS Data Sets data using native Power BI data types.

Connect to SAS Data Sets as a Power BI Data Source

Installing the Power BI Connector creates a DSN (data source name) called CData Power BI SAS Data Sets. This the name of the DSN that Power BI uses to request a connection to the data source. Configure the DSN by filling in the required connection properties.

You can use the Microsoft ODBC Data Source Administrator to create and configure the DSN: From the Start menu, enter "ODBC Data Sources" and select the CData PowerBI REST DSN. Ensure that you run the version of the ODBC Administrator that corresponds to the bitness of your Power BI Desktop installation (32-bit or 64-bit). You can also use run the ConfigureODBC.exe tool located in the installation folder for the connector.

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.

How to Query SAS Data Sets Tables

Follow the steps below to build a query to pull SAS Data Sets data into the report:

1. Open Power BI Desktop and click Get Data -> Other -> CData SASDataSets.
2. Select CData PowerBI SAS Data Sets in the Data Source Name menu and select a data connectivity mode:
   Select Import if you want to import a copy of the data into your project. You can refresh this data on demand.
   Select DirectQuery if you want to work with the remote data.
3. Select tables in the Navigator dialog.

4. 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 row to filter the rows. Right-click a column header to perform actions 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 retrieved by the connector.

   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.

How to Create Data Visualizations in Power BI

After pulling the data into Power BI, you can create data visualizations in the Report view by dragging fields from the Fields pane onto the canvas. Follow the steps below to create a pie chart:

1. Select the pie chart icon in the Visualizations pane.
2. Select a dimension in the Fields pane: for example, name.
3. Select a measure in the Fields pane: for example, borough.

You can change sort options by clicking the ellipsis (...) button for the chart. Options to select the sort column and change the sort order are displayed.

You can use both highlighting and filtering to focus on data. Filtering removes unfocused data from visualizations; highlighting dims unfocused data. You can highlight fields by clicking them:

You can apply filters at the page level, at the report level, or to a single visualization by dragging fields onto the Filters pane. To filter on the field's value, select one of the values that are displayed in the Filters pane.

Click Refresh to synchronize your report with any changes to the data.

At this point, you will have a Power BI report built on top of live SAS Data Sets data. Learn more about the CData Power BI Connectors for SAS Data Sets and download a free trial from the CData Power BI Connector for SAS Data Sets page. Let our Support Team know if you have any questions.
