*_TSER feature class: Each target feature class has a related collection feature class *_TSER. A trigger (feature rule) on the intersection feature class will validate the new features and copy invalid features to _TSER table.
The perimeter is defined by the selected job or by selection of the user.
Before intersection, all old and invalid features inside the perimeter must be deleted.
