Python Connector Libraries for SAP Ariba Procurement Data Connectivity. Integrate SAP Ariba Procurement with popular Python tools like Pandas, SQLAlchemy, Dash & petl.

How to Visualize SAP Ariba Procurement Data in Python with pandas

Use pandas and other modules to analyze and visualize live SAP Ariba Procurement data in Python.

The rich ecosystem of Python modules lets you get to work quickly and integrate your systems more effectively. With the CData Python Connector for SAP Ariba Procurement, the pandas & Matplotlib modules, and the SQLAlchemy toolkit, you can build SAP Ariba Procurement-connected Python applications and scripts for visualizing SAP Ariba Procurement data. This article shows how to use the pandas, SQLAlchemy, and Matplotlib built-in functions to connect to SAP Ariba Procurement data, execute queries, and visualize the results.

With built-in optimized data processing, the CData Python Connector offers unmatched performance for interacting with live SAP Ariba Procurement data in Python. When you issue complex SQL queries from SAP Ariba Procurement, the driver pushes supported SQL operations, like filters and aggregations, directly to SAP Ariba Procurement and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations).

Connecting to SAP Ariba Procurement Data

Connecting to SAP Ariba Procurement data looks just like connecting to any relational data source. Create a connection string using the required connection properties. For this article, you will pass the connection string as a parameter to the create_engine function.

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.

Follow the procedure below to install the required modules and start accessing SAP Ariba Procurement through Python objects.

Install Required Modules

Use the pip utility to install the pandas & Matplotlib modules and the SQLAlchemy toolkit:

pip install pandas
pip install matplotlib
pip install sqlalchemy

Be sure to import the module with the following:

import pandas
import matplotlib.pyplot as plt
from sqlalchemy import create_engine

Visualize SAP Ariba Procurement Data in Python

You can now connect with a connection string. Use the create_engine function to create an Engine for working with SAP Ariba Procurement data.

engine = create_engine("saparibaprocurement:///?ANID=AN02000000280&API=PurchaseOrdersBuyerAPI-V1&APIKey=wWVLn7WTAXrIRMAzZ6VnuEj7Ekot5jnU&AuthScheme=OAuthClient&InitiateOAuth=GETANDREFRESH&OAuthSettingsLocation=/PATH/TO/OAuthSettings.txt")

Execute SQL to SAP Ariba Procurement

Use the read_sql function from pandas to execute any SQL statement and store the resultset in a DataFrame.

df = pandas.read_sql("SELECT DocumentNumber, Revision FROM Orders WHERE OrderStatus = 'CHANGED'", engine)

Visualize SAP Ariba Procurement Data

With the query results stored in a DataFrame, use the plot function to build a chart to display the SAP Ariba Procurement data. The show method displays the chart in a new window.

df.plot(kind="bar", x="DocumentNumber", y="Revision")
