Order of Cleanup Actions
The order of cleanup actions can produce different results. Specify the order
by moving cleanup actions up or down in the list. The action at the top of
the list is performed first.
Setting Cleanup Options
Set the options for each cleanup action individually. For more information,
see the individual help topics about each cleanup action.
Cleaning for Topology
Some types of errors should be fixed before you create a topology. The
following table indicates data errors that should be considered when you are
creating a network or polygon topology. Node topologies do not usually
require cleanup.

Network Topology (page 829).

In addition, if you have closed polylines (polygons) that may be missing
centroids, you should create centroids (page 885) for them before using them
in topology.
