How to Visualize SAP BusinessObjects BI Data in Python with pandas

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 BusinessObjects BI, the pandas & Matplotlib modules, and the SQLAlchemy toolkit, you can build SAP BusinessObjects BI-connected Python applications and scripts for visualizing SAP BusinessObjects BI data. This article shows how to use the pandas, SQLAlchemy, and Matplotlib built-in functions to connect to SAP BusinessObjects BI 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 BusinessObjects BI data in Python. When you issue complex SQL queries from SAP BusinessObjects BI, the driver pushes supported SQL operations, like filters and aggregations, directly to SAP BusinessObjects BI and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations).

Connecting to SAP BusinessObjects BI Data

Connecting to SAP BusinessObjects BI 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.

To connect to your SAP Business Objects BI instance, you must set the following connection properties:

• Url: set this to the rest API URL. After logging into the Central Management Console, choose 'Applications' from the combo box. Double-click on 'RESTful Web Service' and you'll see the access URL. By default it is, http://{Server-Name}:6405/biprws.
• User: set this to the username of your instance.
• Password: set this to the password of your instance.

Follow the procedure below to install the required modules and start accessing SAP BusinessObjects BI 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 BusinessObjects BI Data in Python

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

engine = create_engine("sapbusinessobjectsbi:///?User=username&Password=password&Url=http://myinstance:6405/biprws")

Execute SQL to SAP BusinessObjects BI

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

df = pandas.read_sql("SELECT StoreName, TotalRevenue FROM MyCustomReport WHERE State = 'CA'", engine)

Visualize SAP BusinessObjects BI Data

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

df.plot(kind="bar", x="StoreName", y="TotalRevenue")
plt.show()
