SAP RFC

The following subsections show a graphical representation of the main protocol packets and how to generate them.

First we need to perform some setup to import the packet classes:

from pysap.SAPRFC import *
from IPython.display import display

SAP RFC External packets

for version in [2, 3]:

        print("Packet type: {} Version: {}".format(rfc_req_type_values[req_type], version))
        display(p.canvas_dump())
