Task Variance Properties dialog - Float/Costs tab
You use the Float/Costs tab of the Task Variance Properties dialog to view information on how the currently selected task differs from the state it was in when a specific baseline was produced in terms of its float and costs.
Each row in the dialog displays information in the following columns:
- Property: the type of information being compared.
- Live: the current value in the live data.
- Baseline: the value at the time at which the selected baseline was produced.
- Difference: the difference between the live and baseline values.

To access the Task Variance Properties dialog, click Variance on the Bar and Task Properties dialog.

Field | Description |
---|---|
Cost centre | Select the cost centre for which you want to compare the baseline data against the live data. |
Baseline | Select the baseline that contains the data against which you want to compare the live data. |

Field | Description |
---|---|
Cost from cost centre | The costs that have been recorded against the task, either from a selected cost centre or from all cost centres. |
Actual cost | The amount of cost that has been completed against the task, either from a selected cost centre or from all cost centres. |
Cost remaining | The amount of cost that has yet to be completed against the task, either from a selected cost centre or from all cost centres. |
Income to cost centre | The income that has been recorded against the task, either to a selected cost centre or to all cost centres. |
Actual income | The amount of income that has been completed against the task, either from a selected cost centre or from all cost centres. |
Income remaining | The amount of income that has yet to be completed against the task, either from a selected cost centre or from all cost centres. |
Total float | The amount of time the task can be delayed without affecting the project finish date; the difference between the task's early finish and late finish dates. |
Free float | The amount of time the task can be delayed without affecting any other task or the project finish date; the difference between the task's earliest finish date and the earliest start date of the task's immediate successor. |
Placement |
Whether the task has been placed ASAP, ALAP or ASAP Force Critical on its bar.
|
Buffer task |
Whether the task is a buffer task, ie a task that protects an important date.
|
Original buffer task duration | The duration that a buffer task or an interruptible task had at the point at which it was defined as a buffer task or an interruptible task. |
Critical | Whether the task is on the critical path, as calculated during a reschedule. |
Milestone Placement |
For milestones, whether the milestone has been placed ASAP, ALAP or ASAP Force Critical on its bar.
|
Given date/time | For milestones, the date and time on which the milestone occurs. |
Milestone type |
For milestones, whether the milestone is a Start or Finish milestone.
|
Completed | For milestones, whether the milestone has been completed. |
Early start date | The earliest possible time by which the task can start within the logical and imposed constraints of the plan. |
Free start date | The latest possible time by which the task can start within the logical and imposed constraints of the plan, without affecting the start date of any other task. |
Late start date | The latest possible time by which the task can start within the logical and imposed constraints of the plan. |
Early finish date | The earliest possible time by which the task can be completed within the logical and imposed constraints of the plan. |
Free finish date | The earliest possible time by which the task can be completed within the logical and imposed constraints of the plan, without affecting the start date of any other task. |
Late finish date | The latest possible time by which the task can be completed within the logical and imposed constraints of the plan. |
How do I...

- Select the cost centre for which you want to compare the baseline data against the live data in the Cost centre field.
- Select the baseline that contains the data against which you want to compare the live data in the Baseline field.
