This article describes how plans are organized in OnePlan.
Plan Hierarchies: Parent and Child Plans
A plan may have one or multiple children plans (sub-plans). By selecting the parent plan, the children plans' tasks show as well. The totals and summary row data rollup to the parent plan level.
Your organization can organize different plan types into different Areas. Areas are larger units of organization and functionality in OnePlan. See Create and Manage Areas
