Message text: Reserve spool work processes for processing group
A reservation of spol work processes in the specified quantity has been
configured for the processing group for output requests described by
the parent node (The number 0 means no reservation).
On this server, this number of spool work processes is used exclusively
for requests for this particular group. They remain unused, even if
there is no request for this group, the other work processes are
occupied and other request from other groups are waiting to be
processed. This value therefore implies a restriction of the number of
spool work processes available for other groups corresponding to the
difference between the total number of spool work processes and the
reservation.
If a reservation of the assigned quantity is not required to ensure
that the requests for this group are processed, the reservation can be
reduced, if the remaining work processes are overloaded by requests
from other groups. If there is an overload, but the reservation cannot
be reduced, the total number of spool work processes must be increased
in order to work against the overload.
The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

Configuration Issues: Incorrect configuration settings for the spool parameters can lead to this error. System Resource Limitations: Limited system resources (CPU, memory) can affect the performance and availability of spool work processes.
Solution: Increase Spool Work Processes: Go to transaction code RZ10 or RZ11 to adjust the parameters for spool work processes. Check the parameter rdisp/wp_no_spo which defines the number of spool work processes. Increase this value based on your system's capacity and requirements. Monitor and
