There are 4 object types supported by Database Schema Designer for Permissions.
They are: Functions, Stored Procedures, Tables and Views.
Use the drop-down list "Object Types" to choose which object type is displayed in the list below it.

If you require Permissions on the individual Object level you must define those Permissions in the After Script of the Schema.
With the exception of selecting the Object Type, this screen works in the same way as a Manage screen.
