Project Charging Levels
If you use PeopleSoft Program Management, you can take advantage of a flexible project activity model that supports both a detail WBS for planning, and a cost breakdown structure for accounting. You can use different levels of the WBS for project management and accounting by defining the WBS level at which you want to track project budgets and costs. You can specify a project charging level of WBS level 1, level 2, or level 3, and the system restricts charges to summary and detail activities that are in the specified level. You can also specify a project charging level of all detail activities, in which case you can capture costs on detail activities, but not on summary activities—regardless of an activity's WBS level.
If you use PeopleSoft Project Costing without PeopleSoft Program Management, the project charging level is all detail activities.
