Python SAP rfc module

Thanks for helping me out. There are some more things where I am a little b=
it confused. I will be grateful if you can help me out in that. There are s=
ome points where I fell I need some more help.=0A=0A1. On my machine if I a=
m not having SAP GUI installed then also is it possible to connect to SAP a=
nd act as a RFC Server ?=0A2. Do I need some other information (e.g. some i=
ni file, some parameters to be passed to RFC Server) for server to work?=0A=
3. Do I need to run my python RFC Server exe file in advance so that SAP RF=
C client can use it? Or the SAP RFC client will invoke my app automatically=
?=0A=0AI have also gone through the help available on net for setting up a =
SM59 RFC connection, from pysaprfc site and other sites also. In my case as=
 I don't have SAPGUI on my machine then most probably on SAP SM59 it needs =
to be registered as __explicit host__ . Please correct me if I am going wro=
ng here. And AFAIK in general to work as a server the application need to b=
e already running and listening to incoming connections or the client shoul=
d know the path from which the server application has to be started. So, I =
just want to know whether is it necessary to have SAP GUI installed and con=
figured on my machine before it can host the RFC Server application? Actual=
ly I just want to prepare myself before negotiating with this proposed clie=

You definitely need access to a SAP system to test your application. The li=
brfc32.dll alone is not enough. In order to call a function defined in SAP =
you need at least connection settings (IP or name of the host, and system n=
umber) plus username, password and client number. In the simplest and most =
often case the connection string is something like 'ASHOST =3D <ip or hostn=
ame of SAP system> SYSNR=3D<system number> CLIENT=3D<client> USER=3D<userna=
me> PASSWD=3D<password>'.=0A> In case of a server function (as in your exam=
ple) the connection should be defined from SAP system using transaction sm5=
9 as described in SAP documentation.=0A> If I understand your situation cor=
rectly your client gave you librfc32.dll but you don't have access to their=
 system. In that case you should negociate access to their test or dev syst=
em in order to be able to test your app. The example you sent should work i=
f SAP system is accessible and configured properly (sm59).=0A>=0A> Best reg=
