From which screen in GATES can cargo be frustrated?

Frustration of cargo in GATES (Global Air Transportation Execution System) typically occurs in the Unit Maintenance screen. This is because the Unit Maintenance feature allows users to manage and maintain cargo details, facilitating actions such as frustration, which arises when cargo cannot be processed for shipment due to various issues. The system enables personnel to identify cargo that requires further action, such as resolution of discrepancies or other complications that prevent proper handling and transportation.

The other options cater to different functions: Shipment Tracking is focused on monitoring shipment progress without altering the status of cargo, Cargo Shipment Status provides updates on the state of shipments, but does not facilitate the frustration process, and the Frustration Request serves as a method for entering frustration actions but is not the primary interface for executing them. Thus, the Unit Maintenance screen is the correct place for managing frustrations of cargo in the GATES system.
