Automatic data extraction from SAP using Python

Motive

Well, I am a lazy data engineer who needs to crunch the data from the SAP ERP system every day, so I decided to develop a tool to automate the data extraction process. If you are like me, please go ahead and try it.

Features:

  • Auto login and terminate other working sessions of SAP GUI
  • Refresh system tray
  • Run extraction task based on schedule

GuiXT

Wikipedia: GuiXT is a software component that allows the customization of the SAP user interface. It was developed as a standalone solution in 1998 by Synactive GmbH, Germany, and shortly after that, integrated into SAP GUI by SAP.

You can think of it as a macro tool in SAP, in which you can record your steps and execute that script by other languages. In this case, I use Python.

  • Activate GuiXT

I use the LX02 transaction as the example for this module, and you will see the GuiXT script as below. For any filter, please name it as "inVariable" so that in the Python program, we can change it to whatever we want.
