Constraint fields

Whether a task has been defined as a 'buffer task', ie one that can shrink or expand in size to consume any float, protecting a finish date or any successor tasks and acting as a contingency.

For more information, refer to Working with buffer tasks.

• Specific task - specify specific task(s) on a multi-task bar to which you want the field to refer if required.

Whether a task has been defined as an 'interruptible task', ie one with at least two incoming links, one of which constrains the start of the task and one of which constrains the finish of the task, in which work can be interrupted at some point before the finish of the task, that has been marked as interruptible.

For more information, refer to Working with interruptible tasks.

• Data - whether you want to display information relating to the live data or to a specific baseline.
• Specific task - specify specific task(s) on a multi-task bar to which you want the field to refer if required.

The duration by which a task has been delayed as a result of resource levelling.

For more information, refer to Resource levelling.

• Data - whether you want to display information relating to the live data or to a specific baseline.
• Specific task - specify specific task(s) on a multi-task bar to which you want the field to refer if required.
• Override time unit - the time unit in which to display the information.

A number between 0 and 100 where 0 is the lowest priority and the task is more likely to be affected by levelling, and 100 is the highest priority and the task is less likely to be affected by levelling.

For more information, refer to Setting the levelling priority of tasks.

• Data - whether you want to display information relating to the live data or to a specific baseline.
• Specific task - specify specific task(s) on a multi-task bar to which you want the field to refer if required.

The minimum allocation below which you do not want a resource allocation to be stretched by resource levelling.

For more information, refer to Setting resource levelling options.

• Data - whether you want to display information relating to the live data or to a specific baseline.
• Specific task - specify specific task(s) on a multi-task bar to which you want the field to refer if required.

The minimum duration after which you do not want a resource allocation to be split by resource levelling.

For more information, refer to Setting resource levelling options.

• Data - whether you want to display information relating to the live data or to a specific baseline.
• Specific task - specify specific task(s) on a multi-task bar to which you want the field to refer if required.
• Override time unit - the time unit in which to display the information.

Whether a task should be forced to complete within the time period, shift or work pattern in which it starts. This field enables you to model tasks that must be completed without a break.

For more information, refer to Constraining tasks to complete within a single time period, shift or work pattern.

• Data - whether you want to display information relating to the live data or to a specific baseline.
• Specific task - specify specific task(s) on a multi-task bar to which you want the field to refer if required.

Whether a task is positioned to start as soon as possible (ASAP), as late as possible (ALAP) or forced to be critical (ASAP Force Critical).

For more information, refer to Factors that affect rescheduling.

• Data - whether you want to display information relating to the live data or to a specific baseline.
• Specific task - specify specific task(s) on a multi-task bar to which you want the field to refer if required.

The date of a task's start constraint flag, if one is applied to the task.

For more information, refer to Using constraints.

• Data - whether you want to display information relating to the live data or to a specific baseline.
• Specific task - specify specific task(s) on a multi-task bar to which you want the field to refer if required.

The duration between a task's start date and the date of the task's start constraint flag, if one is applied to the task.

For more information, refer to Using constraints.

• Data - whether you want to display information relating to the live data or to a specific baseline.
• Specific task - specify specific task(s) on a multi-task bar to which you want the field to refer if required.
• Override time unit - the time unit in which to display the information.

Whether a task should be forced to start at the beginning of a new day (according to the task's calendar) following a reschedule, even if the finish dates of the task's predecessors are such that it could otherwise start at some point during the previous day. Setting this field for tasks prevents them from starting at unrealistic times such as 15:34:52 and forces them to start at a time that is more likely to reflect the way in which they are actually worked on.

For more information, refer to Constraining tasks to start on a new day.

• Data - whether you want to display information relating to the live data or to a specific baseline.
• Specific task - specify specific task(s) on a multi-task bar to which you want the field to refer if required.

Whether the tasks on a bar can overlap. You may want to allow the tasks on a bar to overlap in order to plan a unit network in which tasks can overlap on a single bar, rather than planning it over a number of bars, to save space.

For more information, refer to Specifying that tasks on a bar can overlap.

• Data - whether you want to display information relating to the live data or to a specific baseline.
• Specific task - specify specific task(s) on a multi-task bar to which you want the field to refer if required.
