Using the CData ODBC Driver for SAP Ariba Procurement in PyCharm


Connect to SAP Ariba Procurement as an ODBC data source in PyCharm using the CData ODBC Driver for SAP Ariba Procurement.

The CData ODBC Drivers can be used in any environment that supports loading an ODBC Driver. In this tutorial we will explore using the CData ODBC Driver for SAP Ariba Procurement from within PyCharm. Included are steps for adding the CData ODBC Driver as a data source, as well as basic PyCharm code to query the data source and display results.

To begin, this tutorial will assume that you have already installed the CData ODBC Driver for SAP Ariba Procurement as well as PyCharm.

Add Pyodbc to the Project

Follow the steps below to add the pyodbc module to your project.

  1. Click File -> Settings to open the project settings window.
  2. Click Project Interpreter from the Project: YourProjectName menu.
  3. To add pyodbc, click the + button and enter pyodbc.
  4. Click Install Package to install pyodbc.

Connect to SAP Ariba Procurement

You can now connect with an ODBC connection string or a DSN. See the Getting Started section in the CData driver documentation for a guide to creating a DSN on your OS.

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:

  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.

Below is the syntax for a DSN:

[CData SAPAribaProcurement Source] Driver = CData ODBC Driver for SAP Ariba Procurement Description = My Description ANID = AN02000000280 API = PurchaseOrdersBuyerAPI-V1 APIKey = wWVLn7WTAXrIRMAzZ6VnuEj7Ekot5jnU AuthScheme = OAuthClient

Execute SQL to SAP Ariba Procurement

Instantiate a Cursor and use the execute method of the Cursor class to execute any SQL statement.

import pyodbc cnxn = pyodbc.connect('DRIVER={CData ODBC Driver for SAPAribaProcurement};ANID = AN02000000280;API = PurchaseOrdersBuyerAPI-V1;APIKey = wWVLn7WTAXrIRMAzZ6VnuEj7Ekot5jnU;AuthScheme = OAuthClient;') cursor = cnxn.cursor() cursor.execute("SELECT DocumentNumber, Revision FROM Orders WHERE OrderStatus = 'CHANGED'") rows = cursor.fetchall() for row in rows: print(row.DocumentNumber, row.Revision)

After connecting to SAP Ariba Procurement in PyCharm using the CData ODBC Driver, you will be able to build Python apps with access to SAP Ariba Procurement data as if it were a standard database.
