The Exclude from Schedules / Include in Schedules commands part of the Documentation panel allows you to disable/enable the parameter for filtering assembly components in schedules.

Exclude from Schedules / Include in Schedules commands
The first use of the Exclude from Schedules / Include in Schedules command adds a parameter (G.Schedule) to all additional (structural connection) components.
The G.Schedule parameter is available in the Data section of the Properties window for the selected components (structural connection), in the assembly edit mode.

Parameters for filtering assembly components
Another use of the Exclude from Schedules command changes the G.Schedule parameter to False.
Another use of the Include in Schedules command changes the G.Schedule parameter to True.
This parameter allows you to filter structural connection components in the schedules of the assembly.
