RFC user authorization: Since installing GuiXT version 2011 Q4 1 we have been having a problem with RFC access. Are there any changes?

Due to a change in the RFC logon, the SAP RFC library internally calls the function module RFCPING which does nothing, but is part of the function group "SYST" and therefore the authorization for "SYST" is checked.

Please grant the RFC user authorization
