Data Type Date (date field: A type of field whose content is a date. Examples include the Baseline Start and Early Finish fields.)
Entry Type Entered (entered field: A field in which you may type or edit information. This is in contrast with a calculated field, in which Project calculates and enters information.)
Description The Deadline field shows the date you enter as a deadline (deadline: A target date indicating when you want a task to be completed. If the deadline date passes and the task is not completed, Project displays an indicator.) for the task. A deadline is a target date indicating when you want a task to be completed. If the deadline date passes and the task is not completed, Project displays an indicator (indicators: Small icons representing information for a task or resource that are displayed in the Indicators field. The Indicators field is located to the right of the ID field and appears in a number of tables.). A deadline is also shown as an arrow in the Gantt Chart view.
Best Uses Apply a deadline to a task when you want to track a deadline for a specific task but don't want to lock your schedule by setting an inflexible constraint such as Must Finish On (constraint: A restriction set on the start or finish date of a task. You can specify that a task must start on or finish no later than a particular date. Constraints can be flexible [not tied to a specific date] or inflexible [tied to a specific date].) or Finish No Later Than (constraint: A restriction set on the start or finish date of a task. You can specify that a task must start on or finish no later than a particular date. Constraints can be flexible [not tied to a specific date] or inflexible [tied to a specific date].). Such constraints affect scheduling while the Deadline field simply causes an indicator to show if a task has not been completed by its deadline. Add the Deadline field to a task sheet when you want to enter, view, or change the deadlines of tasks in your project. You can also use the Deadline field for sorting, filtering, and grouping by deadline date.
Example Certain tasks in your project should finish by specific target dates. However, you don't want these dates to actually affect how Project schedules the tasks; you just want to be alerted if the tasks are not completed by these dates. Add the Deadline field to the Entry table of the Gantt Chart view, and set the deadline dates for these tasks.
Remarks While setting a deadline does not generate scheduling error messages like date constraints (inflexible constraint: A constraint that is inflexible because it ties a task to a date. The inflexible constraints are Must Finish On and Must Start On.) can, deadlines can affect how Total Slack is calculated.
You can also enter a task deadline in the Task Information dialog box.
If you do want Project to schedule tasks according to a specific finish date, apply either a Finish No Later Than, Finish No Earlier Than, or Must Finish On constraint. You also set task constraints in the Task Information dialog box.
