The SAP Ariba Source ODBC Driver is a powerful tool that allows you to connect with live data from SAP Ariba Source, directly from any applications that support ODBC connectivity.

Access SAP Ariba Source data like you would a database - read, write, and update SAP Ariba Source 0, etc. through a standard ODBC Driver interface.

Connect to SAP Ariba Source Data in Ruby


Connect to SAP Ariba Source data in Ruby with ruby-dbi, dbd-odbc, and ruby-odbc.

The CData ODBC Driver for SAP Ariba Source makes it easy to integrate connectivity to live SAP Ariba Source data in Ruby. This article shows how to create a simple Ruby app that connects to SAP Ariba Source data, executes a query, and displays the results.

Create an ODBC Connection to SAP Ariba Source Data

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

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.

Installing Ruby and Necessary Gems

If you do not have Ruby installed, refer to the Ruby installation page. With Ruby installed, you will need to install the ruby-dbi, dbd-odbc, and ruby-odbc gems:

gem install dbi gem install dbd-odbc gem install ruby-odbc

Create a Ruby App with Connectivity to SAP Ariba Source Data

Create a new Ruby file (for example: SAPAribaSourceSelect.rb) and open it in a text editor. Copy the following code into your file:

#connect to the DSN require 'DBI' cnxn = DBI.connect('DBI:ODBC:CData SAPAribaSource Source','','') #execute a SELECT query and store the result set resultSet = cnxn.execute("SELECT SMVendorID, Category FROM Vendors WHERE Region = 'USA'") #display the names of the columns resultSet.column_names.each do |name| print name, "\t" end puts #display the results while row = resultSet.fetch do (0..resultSet.column_names.size - 1).each do |n| print row[n], "\t" end puts end resultSet.finish #close the connection cnxn.disconnect if cnxn

With the file completed, you are ready to display your SAP Ariba Source data with Ruby. To do so, simply run your file from the command line:
