The User Guided process group for PCBA provides component costs for purchased parts. These typically come from the Component Library, or are provided in the BOM.

In general, feasibility failures for components indicate that no cost could be found for the component, which means that an entry is missing or mispelled in the Component Library. Hovering over the red x icon in the Assembly Details tab confirms a costing failure .

Expanding down to the Purchased Component row provides additional information.
