RFC Logon - user license - multiple logon

Sales person is logged on with user 'USER_A' via SAP GUI in session 1 in order to create, change, view sales orders. User type is dialog = 'A'. User licence is professional. The same sales person starts a 3rd party tool which connect to SAP via RFC Logon with the same user 'USER_A'. The 3rd party tool can also create sales orders via RFC. In Transaction SM04 another session is opened with usertyp 'RFC' (

session 2). Even with parameter 'login/disable_multi_gui_login' = 1 (Note 142724 - prevention of multiple SAPGUI logons) this scenario technically works, because remote function calls (RFC) are not influenced by the profile Parameter.


Is a professional user ( SAP Business Suite Professional User (mySAP Kategorie II / Professional) allowed to logon twice via SAP GUI and RFC? Is this against any SAP license agreement?

Best regards

    Hi Thilo,

    i'm facing the same situation right now and I talked last week wtih our partners for the licensing.

    First thing: the IP it's the same? If so, there should be no problem because it's clearly the same person (with a gui or a third part tool) using the that user. But it's just what they told us, not a general rule so far I know.

    The real answer is... there is a clear answer :)

    You should ask to your licensing partner about it, explaining the scenario (or showing how the people work in real time) to get a better answer.

    There are standards for sure in licensing, but each company could have contracted something specific.

    Dear Simone,

    thanks for your reply.

    We have placed this question to out licensing partner, but so far we have no answer.

    The IP thing is interesting. There are several RFC Connectors for .net, Java, c# etc. out there.

    I think there have to be an clear answer to this questions :-).
