The connector can be used to create ETL applications and pipelines for CSV data in Python using Petl.

Install Required Modules

Install the Petl modules using the pip utility.

pip install petl

Connecting

After you import the modules, including the CData Python Connector for SAP ERP, you can use the connector's connect function to create a connection using a valid SAP ERP connection string. If you prefer not to use a direct connection, you can use a SQLAlchemy engine.

import petl as etl
import cdata.saperp as mod
cnxn = mod.connect("Host=sap.mydomain.com;User=EXT90033;Password=xxx;Client=800;System Number=09;ConnectionType=Classic;")

Extract, Transform, and Load the SAP ERP Data

Create a SQL query string and store the query results in a DataFrame.

sql = "SELECT	MANDT, MATNR FROM MARA "
table1 = etl.fromdb(cnxn,sql)

Loading Data

With the query results stored in a DataFrame, you can load your data into any supported Petl destination. The following example loads the data into a CSV file.

etl.tocsv(table1,'output.csv')
