The Choreo platform from WS02 is a versatile platform designed for low-code and cloud-native engineering. Developers, even those without advanced coding skills, can leverage Choreo's user-friendly low-code environment to simplify application development. When combined with CData Connect AI, users gain immediate cloud-to-cloud access to SAP Ariba Procurement data for applications. This article details the process of connecting to SAP Ariba Procurement using Connect AI and building an application with real-time access to SAP Ariba Procurement data within Choreo.
CData Connect AI delivers a pure cloud-to-cloud interface for SAP Ariba Procurement, enabling you to construct applications within Choreo that utilize live SAP Ariba Procurement data data, all without the need for data replication to a natively supported database. With its built-in optimized data processing capabilities, CData Connect AI efficiently directs all supported SQL operations, including filters and JOINs, directly to SAP Ariba Procurement, capitalizing on server-side processing to swiftly provide the requested SAP Ariba Procurement data.
Configure SAP Ariba Procurement Connectivity for Choreo
Connectivity to SAP Ariba Procurement from Choreo is made possible through CData Connect AI. To work with SAP Ariba Procurement data from Choreo, we start by creating and configuring a SAP Ariba Procurement connection.
-
Log into Connect AI, click Sources, and then click Add Connection
👁 Adding a Connection
- Select "SAP Ariba Procurement" from the Add Connection panel
👁 Selecting a data source
-
Enter the necessary authentication properties to connect to SAP Ariba Procurement.
In order to connect with SAP Ariba Procurement, set the following:
- ANID: Your Ariba Network ID.
- ANID: Specify which API you would like the provider to retrieve SAP Ariba data from. Select the Buyer or Supplier API based on your business role (possible values are PurchaseOrdersBuyerAPIV1 or PurchaseOrdersSupplierAPIV1).
- Environment: Indicate whether you are connecting to a test or production environment (possible values are TEST or PRODUCTION).
Authenticating with OAuth
After setting connection properties, you need to configure OAuth connectivity to authenticate.
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:
- The provider obtains an access token from SAP Ariba and uses it to request data.
- The provider refreshes the access token automatically when it expires.
- The OAuth values are saved in memory relative to the location specified in OAuthSettingsLocation.
👁 Configuring a connection (Salesforce is shown)
-
Click Save & Test
-
Navigate to the Permissions tab in the Add SAP Ariba Procurement Connection page and update the User-based permissions.
👁 Updating 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.
-
Click on the Gear icon () at the top right of the Connect AI app to open the settings page.
-
On the Settings page, go to the Access Tokens section and click Create PAT.
-
Give the PAT a name and click Create.
👁 Creating a new PAT
-
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 SAP Ariba Procurement data from Choreo.
Connect to SAP Ariba Procurement from Choreo
The steps below outline connecting to CData Connect AI from Choreo to create a new application with access to live SAP Ariba Procurement data.
Creating a Construct

-
Select Components from the left sidebar and then click +Create. Next, choose Manual Trigger and then Start from scratch.
👁 Selecting manual trigger
-
Give the manual trigger a Name and Description and click Create.
👁 Creating manual trigger
-
After the trigger is created, click on Edit Code.
👁 Clicking Edit Code
-
The Ballerina Low-Code IDE is displayed. Choreo automatically generates a construct in the low-code diagram
view. Delete this construct by highlighting it and clicking on the trashcan icon.
👁 Showing Ballerina Low-Code IDE
-
Click the + icon towards the top of the screen and select Main from the Add Constructs
toolbar on the right. In the following Function Configuration form, click Save.
👁 Adding a Construct
Adding the CData Connect AI Connector
-
Click the + icon between the Start and End ellipses and click Connector.
👁 Adding a Connector
-
In the Connectors sidebar on the right, search for "CData". Click CData Connect to open the Connector settings pane.
👁 Searching for CData Connector
-
In the Connector settings pane, enter the configuration settings:
- Enter an Endpoint Name for your use. In this example, we use "connectEndpoint".
- In the User field, enter the email address of the CData Connect AI user, wrapped in quotation marks (for example, "[email protected]").
- In the Password field, enter the PAT you generated earlier, wrapped in quotation marks (for example, "SampleToken").
👁 Configuring an endpoint
- After clicking Save, the low-code editor appears with the CData Connect AI logo.
👁 Displaying the new CData connector
Adding a Query Action
- Click the + icon between the new and end shapes, select Action, and then select our existing connector endpoint.
👁 Creating an Action
-
Select query for the connector Operation. There is now an Action pane on the right.
👁 Showing Action pane
- Enter a SQL query to retrieve SAP Ariba Procurement data as the sqlQuery parameter for the query. For example:
SELECT * FROM SAPAribaProcurement1.SAPAribaProcurement.Orders LIMIT 10
-
When writing the query, be sure to specify the Connection Name as the catalog and Data Source Name as the schema. For example, SAPAribaProcurement1.SAPAribaProcurement.
-
These parameters appear on the Connections page of your CData Connect AI dashboard.
Iterating over SAP Ariba Procurement Data
- Click the Show Source icon in the top right of the code editor.
- Add an import statment to import the ballerina/io library:
import ballerina/io;
- Next, add a from statement after the query action to iterate through the results of the SQL query:
check from record{} result in resultStream
do {
io:println("Full Orders details: ", result);
};
- The code for the construct will now look similar to this:
import ballerinax/cdata.connect;
import ballerinax/cdata.connect.driver as _;
import ballerina/io;
public function main() returns error? {
connect:Client connectEp = check new (user = "connect_cloud_username", password="connect_cloud_pat");
stream<record {}, error=""?> resultStream =
connectEp->query(sqlQuery = `SELECT * FROM SAPAribaProcurement1.SAPAribaProcurement.Orders LIMIT 10`);
check from record{} result in resultStream
do {
io:println("Full Orders details: ", result);
};
}
- Click Save to save the action. The diagram should now look similar to this:
👁 Displaying the new endpoint in Ballerina
Deploying the Program
