The PDWare Administer Lists module provides two types of milestone definitions: default milestones associated automatically when a project is created, and optional milestones which can be selected by a user who has edit rights to a project. Default milestones are created in the Milestone table.
Optional milestones are created in the Lookup Lists table.
Select optional milestones by right click in a Milestone row on the Status Entry sheet in the Status module.
