Connect to SAP Ariba Procurement Data in Ruby
Connect to SAP Ariba Procurement data in Ruby with ruby-dbi, dbd-odbc, and ruby-odbc.
The CData ODBC Driver for SAP Ariba Procurement makes it easy to integrate connectivity to live SAP Ariba Procurement data in Ruby. This article shows how to create a simple Ruby app that connects to SAP Ariba Procurement data, executes a query, and displays the results.
Create an ODBC Connection to SAP Ariba Procurement 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 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.
- 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:
- 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.
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 Procurement Data
Create a new Ruby file (for example: SAPAribaProcurementSelect.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 SAPAribaProcurement Source','','')
#execute a SELECT query and store the result set
resultSet = cnxn.execute("SELECT DocumentNumber, Revision FROM Orders WHERE OrderStatus = 'CHANGED'")
#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 Procurement data with Ruby. To do so, simply run your file from the command line:
ruby SAPAribaProcurementSelect.rb
