Sub-Entity Properties can be modified via the list or property page. The operation to access the pages for a sub-entity is same as for Sub-Entity Creation. In addition, it is possible to access these from the Subsystem Navigator. For an entity without the property page, you can modify parameters directly in the corresponding input field of the list page. For an entity with a property page, the modified entity must first be selected in the list page to open the property page, and the properties in that page can then be modified.
