Connect to Real-Time SAP Ariba Source 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 SAP Ariba Source, it provides access to SAP Ariba Source data to build custom applications and more

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

Configure a DSN to connect to SAP Ariba Source data

Installing the Power BI Connector creates a DSN (data source name) called CData PBI SAP Ariba Source 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).

In order to connect with SAP Ariba Source, set the following:

• API: Specify which API you would like the provider to retrieve SAP Ariba data from. Select the Supplier, Sourcing Project Management, or Contract API based on your business role (possible values are SupplierDataAPIWithPaginationV4, SourcingProjectManagementAPIV2, or ContractAPIV1).
• DataCenter: The data center where your account's data is hosted.
• Realm: The name of the site you want to access.
• Environment: Indicate whether you are connecting to a test or production environment (possible values are TEST or PRODUCTION).

If you are connecting to the Supplier Data API or the Contract API, additionally set the following:

• User: Id of the user on whose behalf API calls are invoked.
• PasswordAdapter: The password associated with the authenticating User.

If you're connecting to the Supplier API, set ProjectId to the Id of the sourcing project you want to retrieve data from.

Authenticating with OAuth

After setting connection properties, you need to configure OAuth connectivity to authenticate.

• Set AuthScheme to OAuthClient.
• Register an application with the service to obtain the APIKey, OAuthClientId and OAuthClientSecret.

  For more information on creating an OAuth application, refer to the Help documentation.

Automatic OAuth

After setting the following, you are ready to connect:

APIKey: The Application key in your app settings. OAuthClientId: The OAuth Client Id in your app settings. OAuthClientSecret: The OAuth Secret in your app settings.

When you connect, the provider automatically completes the OAuth process:

1. The provider obtains an access token from SAP Ariba and uses it to request data.
2. The provider refreshes the access token automatically when it expires.
3. The OAuth values are saved in memory relative to the location specified in OAuthSettingsLocation.

Configure the on-premises data gateway to recognize the CData Power BI Connector for SAP Ariba Source

In this section, we will configure the on-premises data gateway to detect the CData Power BI Connector for SAP Ariba Source 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 SAP Ariba Source 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 SAP Ariba Source 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 SAP Ariba Source 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 SAP Ariba Source 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 SAP Ariba Source Username and Password. Click Next.
6. SAP Ariba Source is now connected to Power Apps. Under Display options, expand CData under ODBC and SAP Ariba Source under CData, and a list of all the SAP Ariba Source tables will appear in the panel. When you select any one of these tables, a preview will appear, showing that the SAP Ariba Source 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.
