Connect to SAP SuccessFactors Data as an External Data Source using PolyBase

PolyBase for SQL Server allows you to query external data by using the same Transact-SQL syntax used to query a database table. When paired with the CData ODBC Driver for SAP SuccessFactors, you get access to your SAP SuccessFactors data directly alongside your SQL Server data. This article describes creating an external data source and external tables to grant access to live SAP SuccessFactors data using T-SQL queries.

NOTE: PolyBase is only available on SQL Server 19 and above, and only for Standard SQL Server.

CData Connect Cloud provides a pure SQL Server interface for SAP SuccessFactors, allowing you to query data from SAP SuccessFactors without replicating the data to a natively supported database. Using optimized data processing out of the box, CData Connect Cloud pushes all supported SQL operations (filters, JOINs, etc.) directly to SAP SuccessFactors, leveraging server-side processing to return the requested SAP SuccessFactors data quickly.

Configure SAP SuccessFactors Connectivity for PolyBase

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

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

   You can authenticate to SAP Success Factors using Basic authentication or OAuth with SAML assertion.

   Basic Authentication

   You must provide values for the following properties to successfully authenticate to SAP Success Factors. Note that the provider will reuse the session opened by SAP Success Factors using cookies. Which means that your credentials will be used only on the first request to open the session. After that, cookies returned from SAP Success Factors will be used for authentication.

   • Url: set this to the URL of the server hosting Success Factors. Some of the servers are listed in the SAP support documentation (external link).
   • User: set this to the username of your account.
   • Password: set this to the password of your account.
   • CompanyId: set this to the unique identifier of your company.

   OAuth Authentication

   You must provide values for the following properties, which will be used to get the access token.

   • Url: set this to the URL of the server hosting Success Factors. Some of the servers are listed in the SAP support documentation (external link).
   • User: set this to the username of your account.
   • CompanyId: set this to the unique identifier of your company.
   • OAuthClientId: set this to the API Key that was generated in API Center.
   • OAuthClientSecret: the X.509 private key used to sign SAML assertion. The private key can be found in the certificate you downloaded in Registering your OAuth Client Application.
   • InitiateOAuth: set this to GETANDREFRESH.
4. Click Create & Test
5. Navigate to the Permissions tab in the Add SAP SuccessFactors Connection page and update the User-based permissions.

Add a Personal Access Token

If you are connecting from a service, application, platform, or framework that does not support OAuth authentication, you can create a Personal Access Token (PAT) to use for authentication. Best practices would dictate that you create a separate PAT for each service, to maintain granularity of access.

1. Click on your username at the top right of the Connect Cloud app and click User Profile.
2. On the User Profile page, scroll down to the Personal Access Tokens section and click Create PAT.
3. Give your 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.

Create an External Data Source for SAP SuccessFactors Data

After configuring the connection, you need to create a credential database for the external data source.

Creating a Credential Database

Execute the following SQL command to create credentials for the external data source connected to SAP SuccessFactors data.

NOTE: Set IDENTITY to your Connect Cloud username and set SECRET to your Personal Access Token.

CREATE DATABASE SCOPED CREDENTIAL ConnectCloudCredentials
WITH IDENTITY = 'yourusername', SECRET = 'yourPAT';

Create an External Data Source for SAP SuccessFactors

Execute a CREATE EXTERNAL DATA SOURCE SQL command to create an external data source for SAP SuccessFactors with PolyBase:

CREATE EXTERNAL DATA SOURCE ConnectCloudInstance
WITH ( 
  LOCATION = 'sqlserver://tds.cdata.com:14333',
  PUSHDOWN = ON,
  CREDENTIAL = ConnectCloudCredentials
);

Create External Tables for SAP SuccessFactors

After creating the external data source, use CREATE EXTERNAL TABLE statements to link to SAP SuccessFactors data from your SQL Server instance. The table column definitions must match those exposed by CData Connect Cloud. You can use the Data Explorer in Connect Cloud to see the table definition.

Sample CREATE TABLE Statement

Execute a CREATE EXTERNAL TABLE SQL command to create the external table(s), using the collation and setting the LOCATION to three-part notation for the connection, catalog, and table. The statement to create an external table based on a SAP SuccessFactors ExtAddressInfo would look similar to the following.

CREATE EXTERNAL TABLE ExtAddressInfo(
  address1 COLLATE [nvarchar](255) NULL,
  zipCode COLLATE [nvarchar](255) NULL,
  ...
) WITH ( 
  LOCATION='SAPSuccessFactors1.SAPSuccessFactors.ExtAddressInfo',
  DATA_SOURCE=ConnectCloudInstance
);

Having created external tables for SAP SuccessFactors in your SQL Server instance, you are now able to query local and remote data simultaneously. To get live data access to 100+ SaaS, Big Data, and NoSQL sources directly from your SQL Server database, try CData Connect Cloud today!
