SAP Error Message - Details

• Message type: E = Error

• Message class: TG - Messages for Upgrade Repository Switch

• Message number: 312

• Message text: Die interne RFC Ausnahme & wurde ausgelöst, der RFC abgebrochen

Was verursacht dieses Problem?

There are various reasons why an RFC connection could not be set up by
an external program (here "R3up"):
The DDIC password is not correct (message "not authorized")
The logon language is not supported (R3up: system language)
The host name of the application server is not known to the gateway
The gateway addressed (= gateway host plus gateway service) does not
exist, is not running, or cannot be reached.

Systemantwort

The upgrade stops with an error message.

Wie behebe ich diesen Fehler?

Check the parameters entered. The working directory (this is the tmp
subdirectory for R3up) contains a trace file "dev_rfc" with information
about the error. If the trace is not detailed enough, use the following
traces as well:
In the environment of the process, set "CPIC_TRACE=2".
Also set the system trace (profile parameter rdisp/trace) to "2".
Activate the trace in the gateway (R3up: RfcTrace=ON in R3up.par)
