Contact your system administrator and give him or her the number of the
error message.

Procedure for System Administrators

Check that the required RFC destination has been configured correctly.
Incorrect information about the user name in the RFC destination has
probably caused the connection test to fail. Call transaction SM59 and
select the given connection from the list of destinations of type 3
(ABAP connections). Run a connection test for this destination. If the
connection test fails, check the following:
Check whether the password for the user in the settings under "Logon &
Security" is correct.
Check whether the Unicode setting under "MDM" matches the system
information.
Check whether the character conversion settings for the destination are
correct.
Under "Special Options", check whether the qRFC version setting is set
to the classic qRFC version.

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