You can disable automatic re-scheduling within Unifier Schedule Sheet to:
- Schedule Activities manually.
- Integrate Activities with their dependencies with the same schedule as exists in P6 and MPP.
Disabling Automatic Scheduling of Activities
When Activities with dependencies are integrated by Direct Integration with P6, or imported through MPP XMLS, the activities are re-scheduled automatically within Unifier Schedule Sheet to honor the dependencies, leading to Data change. You can disable this automatic reschedule in Schedule sheet to integrate or import the data as is and to schedule the Activities manually, if desired.
To enable or disable auto-scheduling:
- Go to the Schedule Sheet Properties window, General tab.
- Select your option in Auto-Schedule field. The default selection is Enable.
In the Schedule Sheets log, the column Auto-Schedule displays the condition of the sheet.
When the auto-scheduling is disabled:
- You will be able to edit the Activity Properties of a particular Activity, for example Start Date, Finish Date, Duration, Predecessor, Dependencies, etc. The properties of the dependent activities are not impacted because of disabling automatic scheduling is disabled.
- You can, manually, reschedule the schedule sheet to implement your changes by refreshing it through manual Schedule refresh, Cost and Schedule refresh, or enabling scheduled refresh (Set Frequency). These options are available under Refresh option in the log toolbar.
- After changing the Activity Properties of individual activities, when the schedule sheet is refreshed manually or through Schedule refresh, then the entire schedule sheet will be re-scheduled. The impact on dependent activities can be reviewed after refresh.
- The refresh status of schedule sheet is displayed on Schedule Sheet Refresh window (History Details window).
- No updates will take place for resource rates on the master schedule sheet and also update to shell cost sheet with corresponding assignment costs until you allow manual scheduling through manual or Schedule refresh. Once the schedule sheet is manual scheduled, the updates will take place.
- On clicking Update > Resource Utilization (on the master schedule sheet) and also Update > Resource Utilization and Cost Manager, the following alert message is displayed: Cannot update cost till Sheet is scheduled.
Calendar
When the calendar that is defined for a particular Activity is changed in the Activity Properties, then Unifier changes the Finish Date. In this case, if the auto-scheduling is disabled, then no impact of this change is reflected in the dependent activities.
When the calendar that is defined for a particular Schedule Sheet is changed in the Schedule Sheet Properties, then the next time you open the schedule sheet, the following message is displayed: Schedule sheet requires a refresh due to modifications to a Calendar or Rates associated to a Role on a Resource. Do you want to refresh schedule sheet?
If you select Yes, then the schedule sheet will be rescheduled on refresh, as an impact of Calendar change, irrespective of whether Auto-scheduling is enabled or disabled.
If you select No, then no impact of Calendar change is reflected in the schedule sheet.
