Cost data that involves roll-ups from other sources is recalculated system-wide on a periodic basis. These types of cost data can include the following possible scenarios:
Work plan tasks roll up planned and actual cost data to summary tasks
Work plan actual cost data rolls up to the project financial summary
Project actual cost data rolls up to the program financial summary
Since these roll-up calculations are performed periodically, cost data for one entity may not match its dependent entity until the next calculation interval.
Periodic cost roll-up is performed system-wide and is governed by the
server.conf parameter described in Table 2-2. server.conf parameter for periodic cost calculations and scheduled services described in Table 2-3. Scheduled services for periodic cost calculations.
Periodic roll-up of other information is also performed system-wide:
Roll-up of task information to summary tasks is deferred when resources enter task actuals through the My Tasks portlet or time sheets.
Calculation of schedule exceptions and schedule health for work plans is deferred when resources enter task actuals, or when work plan schedule information is updated through Microsoft Project.
These calculations are governed by the scheduled services described in Table 2-4. Scheduled services for work plan information.
