When connected to a P6 Professional database: The value is converted to hours based on hours per timeperiod settings defined in Admin Preferences or in the default project calendar, depending on an administrative preference (Admin Preferences, Time Periods tab).
This option is disabled when Actual Dates are used to schedule progressed activities.ĭefine critical activities as: Choose the method to use to identify critical activities in the project.
The successor's start date is the predecessor's internal early start plus any remaining lag.
The expired lag is calculated as the number of workperiods between the actual start and the data date. The successor's start date is the data date plus any remaining lag.Ĭhoose Early Start when the successor's start depends on the amount of work that the predecessor activity accomplishes. You can choose to subtract the lag from the predecessor's actual start date or its internal early start date.Ĭhoose Actual Start when you want the successor's start to depend on the time elapsed from the predecessor's actual start (regardless of the amount of work that has been accomplished in the predecessor activity). The Actual Dates option can cause negative total float if the schedule has actuals after the Data Date.Ĭalculate start-to-start lag from: When a start-to-start relationship exists and the predecessor starts out of sequence, the successor activity is delayed until that expires and all predecessor relationships have been satisfied.When you choose Actual Dates, backward and forward passes are scheduled using actual dates. When you choose Progress Override, network logic is ignored and the activity can progress without delay. When you choose Retained Logic, the remaining duration of a progressed activity is not scheduled until all predecessors are complete. When scheduling progressed activities use: Specify the type of logic used to schedule activities that are in progress. Use this option to calculate the costs of resource and role assignments that are assigned multiple rates. Recalculate assignment costs after scheduling: Mark to recalculate resource and role costs after scheduling the open projects. Level resources during scheduling: Mark to level resources automatically each time you schedule projects. If you clear this checkbox, changes to activities are reflected in the schedule after you calculate the schedule. Schedule automatically when a change affects dates: Mark to calculate the schedule each time a significant change is made to an activity, relationship, or resource. Use Expected Finish Dates: Mark to schedule activity finish dates as the expected finish dates. Make open-ended activities critical: Mark to designate open-ended activities as critical activities when you schedule the projects. Do not mark this option if you want to preserve activity dates dependent on external relationships to projects that are not in the same database as the project being scheduled.Ignore relationships to and from other projects: Mark to ignore activity relationships between projects.
