The System Tree Browse window shows the systems that have been defined (excluding the property system) and their levels in a hierarchical fashion. The hierarchy tree shows the name of each system that has been set up in the System Definitions table. Below each system is then shown the top level objects for that system, below them are level two objects, and so on. The system Tree Browse window also shows any assets that have been linked to the system, at the appropriate levels.
If an item has a plus sign (+) then there are more items below it in the hierarchy. You can click on the plus sign to expand the next level in the hierarchy. When a level in the tree is expanded, the plus sign will turn to a minus (-) sign. If you click on the minus sign, the level will be collapsed.
This window is a visual representation of the system hierarchy.
