Scheduling Projects

To display and/or use the default scheduling settings, click Default in the Schedule Options dialog box.

For more information on additional scheduling options, refer to the Help.

The module employs the Critical Path Method (CPM) scheduling technique to calculate project schedules. CPM uses activity durations and relationships between activities to calculate project dates. This process is performed in two phases or “passes” over the activities in a project.

The first pass or “forward pass” calculates the early start and early finish dates for each activity, based on the start or finish dates of predecessor activities as well as the duration of the activity itself.

The second pass or “backward pass” calculates the late start and late finish dates for each activity, based on the start or finish dates of successor activities as well as the duration of the activity itself. The free float and total float for each activity are recalculated.

You can schedule one project or all projects in a particular EPS node.

Schedule a project Open an individual project or the node that contains the projects you want to schedule. Choose Tools, Schedule. The Schedule dialog box lists the number of projects to be scheduled, along with the earliest data date of all open projects. You can change the data dates for individual projects when you apply actuals (choose Tools, Apply Actuals.)

A forecast start date is shown if you manually changed the start date of a project by dragging the project bar to a new timeframe in Primavera’s Web Portfolio Management application or in Tracking layouts. You can choose to use this new date instead of the project’s planned date and current data date when you schedule the project. Mark the Set Data Date and Planned Start to Project Forecast Start During Scheduling option. If multiple projects are open, each with a project forecast start date, the forecasted start date is used from each project during scheduling.

For organizations using Primavera ProjectLink, you cannot schedule Microsoft Project (MSP)-managed projects in the Project Management module. For more information on Primavera ProjectLink, refer to the Primavera ProjectLink Help in Microsoft Project (available only if Primavera ProjectLink is installed).You can access the help by clicking the Help button on any ProjectLink screen.

dependent on external relationships to projects that are not in the same database as the project being updated.

Mark to level resources while scheduling the open projects.

Mark to recalculate resource and role

assignment costs after you schedule the project(s).

Click the Advanced tab to specify additional options for determining critical activities based on multiple float paths.

Automatic scheduling and leveling You can also choose to calculate the schedule each time activity data change, rescheduling activities that have changed significantly and rescheduling any activities affected by the change to the first activity. Mark the Schedule Automatically When a Change Affects Dates checkbox in the General tab of the Schedule Options dialog box to recalculate the schedule each time a significant change is made to an activity, relationship, or resource. If you turn off automatic scheduling, changes to activities will not be reflected in the schedule until you calculate the schedule again. You can also choose to level resources during automatic scheduling. To enable leveling of resources, mark the Level Resources During Scheduling checkbox in the General tab of the Schedule Options dialog box.

After the forward pass, if a Must Finish by Date is specified in the Project Details Dates tab, the backward pass is calculated using the must finish by date rather than the schedule end date.

Schedule project data as a service Choose Tools, Job Services, then click Add. Select Schedule in the Service Type field. Specify a number in the Job # field to indicate the sequence in which the service should be performed, if more than one service is listed. Type a brief description of the service in the Job Name field. In the Status field, select Enabled to activate the scheduling service. You can suspend a service at any time by selecting Disabled in the Status field. In the Run Job area on the Job Details tab, schedule when the service should be run: every day at a specific time, or weekly, every two weeks, or monthly on a day and time you specify.

Click the Job Options tab to select the projects/EPS nodes the job service will schedule.

In this example, projects are scheduled each week on Friday.

Mark to log information about the service to a file you specify.

You must have the appropriate access rights to set up job services. The Job Service does not interact with the module client when running jobs. All jobs are run on the server(s) on which the Job Service is installed.
