Fill hours worked in SAP Netweaver Automatically

February 1, 2016

Continuing the theme of automation, one of the most repetitive tasks if you work for a big company is timesheets. So I set out to rectify this by scripting it!

Start with you configuration, I named mine hours.ini:

[DEFAULT]
url = FILL_ME_IN
username = FILL_ME_IN
password = FILL_ME_IN

then we need the magic of Selenium to do the heavy lifting, so we install it:

$ pip3 install selenium

I called this script, unsurprisingly hours.py:

#!/usr/bin/env python3
