A sub-project or change level can be configured below the project level. All rules that apply to working between the plant and project level also apply to the sub level.
To claim items from a plant to the sub configuration, it is necessary to claim from plant to project, then from project to the sub-configuration. This ensures consistency when the data is finally merged back up the configuration hierarchy to the as-built level.
To configure a sub-configuration below a project:
-
In Schema Editor, create a new class definition and realize the ISPFConfigurationItem interface.
-
Set the Dependent Configuration property on the class definition to SPFProject so that the class definition can only be created in the project configuration.
-
Use the CreateObjectAndRel method to configure the shortcut menu item New Sub-Project on the Project menu.
