The View menu gives you two options – Show Routings with Incomplete Cost and Show Uncosted Processes within Visible Routings. Using these options, you can create different views of the Routing Selection window:

If both options are unchecked, only the routings that have been costed without warnings are displayed.

If the Show Routings with Incomplete Cost option is checked, routings that costed with warnings and available routings that were not costed are displayed in addition to the routings that were costed without warnings.

If the Show Uncosted Processes within Visible Routings option is checked, all uncosted nodes within the routing are displayed. A node could be uncosted if the process it is representing is not required for manufacturing the component or has been manually excluded from the routing.
