Connect to Real-Time SAS Data Sets Data in Power Apps Using Dataflows to Build Custom Applications

Power Apps is a suite of apps, services, and connectors that allows users to build custom applications with minimal or no coding. It empowers businesses to create tailored apps that solve specific business challenges, automate workflows, and integrate with various data sources, including Microsoft Dataverse, SQL Server, and third-party services.

Dataflows in Power Apps simplify the process of importing, transforming, and loading external data into Microsoft Dataverse or other storage systems. They allow users to connect to multiple data sources (like Salesforce, Excel, or SQL databases), clean or shape the data, and store it in Power Apps. When paired with the CData Power BI Connector for SAS Data Sets, it provides access to SAS Data Sets data to build custom applications and more

This article demonstrates how you can easily connect to SAS Data Sets using the CData Power BI Connector for SAS Data Sets and integrate your SAS Data Sets data through the Power Apps on-premises data gateway.

Configure a DSN to connect to SAS Data Sets data

Installing the Power BI Connector creates a DSN (data source name) called CData PBI SAS Data Sets Sys. 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 a new DSN or configure (and rename) an existing DSN: From the Start menu, enter "ODBC Data Sources." 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).

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.

Configure the on-premises data gateway to recognize the CData Power BI Connector for SAS Data Sets

In this section, we will configure the on-premises data gateway to detect the CData Power BI Connector for SAS Data Sets installed on your system. If you haven't installed the data gateway yet, you can download it from Microsoft's official website.

Set Up the Power BI Gateway

Follow the given process to configure the on-premise data gateway on your machine:

1. Download and install the on-premises data gateway (recommended) option.
2. Sign into the gateway.
3. Create a name for the new gateway and specify a recovery key.
4. Open the new gateway, navigate to the Connector tab, and select the path C:\Program Files\CData\CData Power BI Connector for SAS Data Sets from the folder. Click on Apply.

   NOTE: Select the folder where the gateway will search for the CData Power BI Connector.

5. Once the CData Power BI Connector for SAS Data Sets is identified by the gateway, you're good to go.

Configure a dataflow connection in Power Apps

Once the on-premise data gateway is configured and a new gateway is created, follow these steps to create a dataflow that pulls in the SAS Data Sets data into Power Apps:

1. Open Power Apps.
2. Select Dataflows from the left panel on the Power Apps screen and click + New Dataflow.
3. Provide a name to the dataflow and click Create.
4. Select ODBC from the list of data sources.
5. On the ODBC Connection settings screen, use the connection details you set up earlier by entering DSN=Connection name (in this case, DSN=CData PBI SAS Data Sets Sys) in the connection string. The on-premise data gateway will display available gateways for connection - select the one you created. Due to the current specifications of Power Apps dataflows, authentication is required for ODBC connections. Choose Basic as the authentication type and enter the SAS Data Sets Username and Password. Click Next.
6. SAS Data Sets is now connected to Power Apps. Under Display options, expand CData under ODBC and SAS Data Sets under CData, and a list of all the SAS Data Sets tables will appear in the panel. When you select any one of these tables, a preview will appear, showing that the SAS Data Sets data is correctly referenced through the Power BI connector and on-premise data gateway. Next, click on Transform Data.
7. On the query editing screen, if no column conversion is needed, you can skip this step and proceed by clicking on Next.
8. In the Choose destination settings screen, you can select how the selected table needs to be loaded by choosing options like Load to new table, Load to existing table, and Do not load. You can also change the Table display name and description as required.
9. Finally, choose how you'd like to update your data: Refresh manually or Refresh automatically. In this case, we have set it to Refresh automatically. By scheduling it to update every 45 minutes, as shown below, data will be collected and registered every 45 minutes timeframe, ensuring the most up-to-date information is always available. (You can select any timeframe based on your convenience)
10. Click on Publish. The dataflow will now be created, published, and displayed as a part of the dataflow list on the Dataflows screen.
