Active Topology Alternative

The Active Topology alternative manages all active topology states. That includes the Active Topology Mode state (refer to the System tab) as well as Is Active? state for individual elements.

Navigation: Active Topology alternatives are listed in the Alternatives docking window. Double click in the treeview to edit the desired Active Topology alternative.

Active Topology System Data Tab

As noted above, the Active Topology Mode state is managed with the alternative. The controls shown here work similar to the ones on the Edit Active Topology Mode Dialog, so refer to that topic for more details.

Note: The Apply Queries button will only be enabled when the alternative you are editing is current (based on the current Scenario).

Element Tabs (one for each element type)

There is a tab for each element type, which contains a table with four columns. The first three columns are common across all alternatives. The first column indicates if each record represents Base Data (yellow/checked), Local data (editable/checked) or Inherited data (editable/unchecked). The second and third columns are the element ID and Label.

The fourth column (Is Active?) is specific to the Active Topology Alternative and allows you to choose whether the corresponding elements are active in the current alternative. To make an element inactive, uncheck Is Active? checkbox for the row that corresponds to that element.

Note: The editability of the Is Active? column will vary based on the Active Topology Mode setting (on the Active Topology System Data Tab). The column will be disabled when using Query Based mode (because the Is Active state is automatically determined based on the queries you defined).

Note: The Active Topology Selection Tool is the best way to enable/disable portions of the system.

The following buttons are available:
