SAP and Python (SAP GUI Scripting, PyRFC)

This is a collection of my notes and code snippets.
I work with SAP on Windows 10 with SAP GUI for Windows 7.50.
On my work account I don't have administrative rights and access to SAP NetWeaver RFC SDK.

Prequisities

Because I don't have access to SAP NetWeaver RFC SDK, I am using a 32-bit sapnwrfc.dll library provided with SAP GUI installation, which forces me to use a 32-bit version of PyRFC. PyRFC in compiled 32-bit version is only available for Python 2.7.

Extracting Python 2.7 from MSI Windows Installer

I install this way because a normal installation requires admin privileges.

msiexec /a python-2.7.15.msi /qb TARGETDIR=C:\Python27

Installing pip, setuptools, pywin32 (for SAP GUI Scripting)

C:\Python27\python.exe -m ensurepip --default-pip
C:\Python27\python.exe -m pip install --upgrade pip setuptools
C:\Python27\python.exe -m pip install --upgrade pywin32

Installing PyRFC for Python 2.7 (for SAP RFC)

C:\Python27\Scripts\easy_install.exe https://github.com/SAP/PyRFC/raw/master/dist/pyrfc-1.9.3-py2.7-win32.egg

Adding Python and sapnwrfc.dll to PATH variable

1. Press Windows logo key + R and run rundll32 sysdm.cpl,EditEnvironmentVariables.
2. Add C:\Python27, C:\Python27\Scripts and C:\Windows\SysWOW64 to PATH variable.
