The Designer permits various subsystems (for example, trade accounting and the research system) to be set apart within a single configuration at the design stage.
For each configuration object, you can specify what subsystem the given object belongs to.

Objects can be assigned to several subsystems. This permits rapid adjustment of the configuration to various types of activity and selection of objects belonging to a particular subsystem.

"Subsystems" objects are created on the Common / Subsystems branch of the configuration object tree.
