¿Qué causa este problema?

The host system that you specified for the execution of your job is not
defined in the operation mode that is active when your job is started.
You have either specified that your job is to be started when a specific
operation mode becomes active, or that it is to be started on a specific
date and at a specific time.
The job can only be executed, if the host is active as an unconfigured
instance in the SAP system, if the background controller attempts to
start the job. An unconfigured instances must be started manually; it is
not started automatically as part of the operation mode.

Respuesta del sistema

El sistema emite un mensaje de error y no le permitirá continuar con esta transacción hasta que se resuelva el error.

¿Cómo arreglar este error?

If possible, you should leave the host system field empty and save the
job again. The specification of a host system for the execution of a job
is only advisable if the job requires a resouce that is only available
on this host system. When you specify a host system, it also means that
the automatic load balancing mechanism of the background controller has
no effect.
If you need to specify a host system, you should use the
<DS:TRAN.RZ04>Computing Center Management Systems</> to determine when
the host that you require is active in the SAP system.
