CNVMBTRFC043 - Overview

• Message type: E = Error

• Message class: CNVMBTRFC - Messages used in RFC Management and its objects

• Message number: 043

• Message text: Unicode setting for RFC Destinations not correct. Check destinations.

What causes this issue?

One or several of your destinations have not the correct unicode flag.
When your system is unicode and the system where you want to create a
connection to is unicode then the unicode flag for the destination has
to be set to unicode. If this is not the case then you get this error
message.
To find the error causing destination determine the destinations you
want to use. For each of the destinations call the transaction SM59. In
the application toolbar you have the 'Unicode Test'. Do the unicode
check by clicking on the 'Unicode Test'. You will get a message whether
your destination is unicode or not. Under tab 'MDMP & Unicode' you
find the unicode flag for that destination. If the system where you have
called the SM59 and the system of the destination are unicode then the
unicode flag must be set. If not, the Non-unicode flag has to be set.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
