Systems are created by using the Generate system by catalog
. System schema
uses the system catalog and they are under the General System which is
a root system.

Creating new systems under the root system, the root system has its configuration model, so,
the configuration model automatically copies from the parent root system to the child
systems.


There are four cases while creating the new system by using the Generate System by Catalog:
- Configuration does not set for root system: If the root system
does not have configuration, then its child system also does not have configuration.
Effectivity does not get applied to the child system or operation here, the root system
does not have the configuration model.

So, the child system also does not have configuration and effectivity.

- Root system has configuration: If the root system has
configuration, then this configuration get copied from root system to child system, and
the effectivity get applied in child Systems/Operations. Here, the root system has its
configuration model.

Creating a new system under the root system, the configuration model copies from
the root system to child systems, and effectivity get applied in child systems or
operations.

- System structure catalog has it's configuration model: If the
system structure catalog has a configuration model, then the root system configuration
overrides on the system structure that has a catalog configuration. Here, the system
structure catalog has their own configuration.

But the root system, has different configuration.

When system structure catalog created systems under root system, root system
configuration overrides on system structure catalog configuration.

- System structure catalog does not have configuration model: If
the system structure catalog does not have the configuration model, then Configuration and
effectivity have carried forward from the root system. Here, the system structure catalog
does not have their own configuration.

Configuration, and effectivity carries forward from root system to system structure
catalog.
