Outlining an activity's start date-time in the graphical planner
Instead of dragging and dropping an activity to reschedule it, you can also manually enter an activity's start date-time and thus outline it on the graphical planner. This method provides greater accuracy. You can also select multiple activities, either horizontally or vertically, and outline their start date-times in one go. In that case, the selected activities must have the same maintenance regime and scheduling method. Also, there should be no orders generated yet for these activities.
Procedure
1. Go to Maintenance Planner.
2. Make relevant selections on the various levels and proceed to Definitions & schedules.
3. Select the Graphical planner view.
4. In the graphical planner, select the single activity (click), multiple activities (CTRL+click) or activity sequence (right-click, followed by clicking Select future activities) whose start date-time(s) you want to adjust.
Refer to Selecting future activities in the graphical planner for information on selecting an activity's future sequence.
5. Right-click and select Outline activities.
This option is not available if orders have been generated for the activity.
6. In the Select a date dialog, select a new start date-time for moving the selected activity/-ies and click OK.
The field Outline activities with offset is set to Yes by default, which means that the start dates of all selected activities will be moved with the selected time interval as the first activity.
* 
If you want to move multiple similar activities from different timelines to the same start date-time, set this field to No. The outlining moves all activities to the same selected date. Note that it is not allowed to have two activities on the same date-time for one maintenance activity definition.
If you selected a sequence of activities, the first activity is the reference. All future occurrences are rescheduled with the same interval (offset) as the first activity in the sequence.
If you selected activities with different start dates, the activity on which you start the outline will be used as reference and all other activities will be moved with same offset.
Example of outlining with offset:
Activity 1 = on January 1st.
Activity 2 = on January 5th.
Select both activity dates in the graphical planner.
- Outlining Activity 1 to 1 February will move Activity 2 to 5 February (offset = +4 days)
- Outlining Activity 2 to 1 February will move Activity 1 to 28 January (offset = -4 days)
The activities are rescheduled to their new date-time.
See Moving multiple activities in the graphical planner for information about moving a sequence of activities on the planner.
