criteria, or the system attempts to create an overview of SAP systems
that currently support background processing.
This message means that the system attempted one of these operations,
but was not successful. The reason for this is that system could not
create the overview of currently active SAP servers.

System Response

The system issues this message. Depending on the operation performed,
the name of the target computer may have to be left blank, or the
system cannot create and display the overview.
Please note that the field can remain unspecified. If so, the load
situation at execution time of the job determines the computer where
the job is run.

How to fix this error?

Make sure that this SAP system is logged on to the corresponding SAP
message server and that the message server is active. To do this, call
transaction "SM51" and check the displayed list to see whether this SAP
system is contained therein. If the system cannot create the list,
please contact the SAP system administrator in charge in order to solve
the problem.
Please also note that the name of the target computer is not a required
entry. If nothing is specified, the load situation at execution time
of the job will determine the computer where the job runs.
