Create SAP Ariba Source-Connected Applications in Appsmith

Appsmith is an open-source internal tool builder that allows teams to quickly and easily build a UI to help improve their business operations. When combined with CData Connect Cloud, you gain immediate access to SAP Ariba Source data for business applications. This article outlines the process of connecting to SAP Ariba Source using Connect Cloud and creating a basic application from SAP Ariba Source data within Appsmith.

CData Connect Cloud offers a pure SQL Server, cloud-to-cloud interface for SAP Ariba Source, enabling the creation of business applications directly from live SAP Ariba Source data within Appsmith, all without the need for data replication to a native database. As you build applications, Appsmith generates SQL queries to gather data. With its inherent optimized data processing capabilities, CData Connect Cloud efficiently channels all supported SQL operations, including filters and JOINs, directly to SAP Ariba Source. This leverages server-side processing to swiftly deliver the requested SAP Ariba Source data.

Configure SAP Ariba Source Connectivity for Appsmith

Connectivity to SAP Ariba Source from Appsmith is made possible through CData Connect Cloud. To work with SAP Ariba Source data from Appsmith, we start by creating and configuring a SAP Ariba Source connection.

1. Log into Connect Cloud, click Connections and click Add Connection
2. Select "SAP Ariba Source" from the Add Connection panel
3. Enter the necessary authentication properties to connect to SAP Ariba Source.

   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.
   
4. Click Create & Test
5. Navigate to the Permissions tab in the Add SAP Ariba Source Connection page and update the User-based permissions.

Add a Personal Access Token

When connecting to Connect Cloud 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 Cloud. 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 Cloud 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, we are ready to connect to SAP Ariba Source data from Appsmith.

Create an Appsmith Application from live SAP Ariba Source Data

To establish a connection from Appsmith to the CData Connect Cloud Virtual SQL Server, follow these steps:

Connect to SAP Ariba Source in Appsmith

1. Log in to your Appsmith instance and create a new application.
2. In the new application, open the Data page and select Bring your data.
3. On this page, you can search for Microsoft SQL Server and select it as your data source.
4. Enter a name for the new data source and then enter the following connection settings:
   • Host address: tds.cdata.com
   • Port: 14333
   • Database name: enter the Connection Name of the CData Connect Cloud data source you want to connect to (for example, SAPAribaSource1).
   • Username: enter your CData Connect Cloud username. This is displayed in the top-right corner of the CData Connect Cloud interface. For example, test@cdata.com.
   • Password: enter the PAT you previously generated.
   
5. Click Test configuration to confirm a successful connection, then click Save to save the datasource.

Create a new query

With a connection configured to a datasource, we can add a SQL query to actually retrieve data from the data source.

1. On the screen with the new data source, click New Query.
2. This opens the Query Editor to enter a SQL query to select data. To assist with specifying a SQL query, use the Explorer of CData Connect Cloud to preview the SQL queries and the data you want to retrieve.
3. After creating the SQL query, return to the Query Editor in Appsmith and enter the SQL query, then click Run.
4. Once the query successfully runs, all that remains is to set up the Page to display the data retrieved.

Display SAP Ariba Source data

1. Open the UI tab and click New UI element.
2. Choose a new UI element to grab, then drag and place the element on the page.
3. Click Connect data on the new UI element, then select the query previously created.
4. With the data connected, it is then displayed in the UI element.

Deploy the application

With the SAP Ariba Source data connected to the UI elements in the application, we can deploy the Application. To do this, click Deploy in the top-right corner of Appsmith, then the application is opened in a seperate window displaying the SAP Ariba Source data.
