About date constraints

In addition to using dependencies, durations, and lag or lead times, you can further constrain when a task begins or ends. In the schedule grid, you can enter dates for a task that restrict when it may begin or end.

Column

Description

Fixed Date

Establishes a permanent date when a task must begin. A fixed date does not move when a schedule is delayed or accelerated.

Most tasks do not use a fixed date, and begin or end in relation to the predecessors tasks.

Not Before

Establishes the earliest date when a task can begin. Though a task cannot begin before the indicated date, the task can begin after the date.

If you provide a date in the Not Before column for a critical task, Sage 100 Contractor adjusts the start and finish dates for subsequent tasks.

Not After

Establishes the latest date when a task can begin.

If you provide a date in the Not After column for a critical task, Sage 100 Contractor adjusts the start and finish dates for subsequent tasks.

Late Start

Displays the last day a non-critical task can begin and remain on schedule. Only for tasks with float.

Late Finish

Displays the last day a non-critical task can end and remain on schedule. Only for tasks with float.
