Reschedule errors

A number of errors can arise during a reschedule. If an error is detected, Asta Powerproject tries to recover but may abandon the reschedule if the error is unrecoverable.

Errors that can arise during a reschedule include:

A task cannot be rescheduled because there is not enough time in its calendar to schedule the time required.
A task is dependent on an unschedulable task.
A task is in a link loop.
A task's constraint conflicts with its parent's constraint flag.

If a task cannot be rescheduled, Asta Powerproject marks the whole bar as being unschedulable by selecting the Unschedulable check box in the Details section of the Bar tab of the Bar and Task Properties dialog.

A warning popup appears following a reschedule in which a link loop is found, a task has negative float, a finish flag has been violated or an object has failed to update due to locks or permissions. The popup states the problem, or problems, that were found during the reschedule.

You can click a hyperlink in the popup to open a new view that contains only the tasks that caused the reschedule problem(s), enabling you to identify and correct the problem(s) quickly.

Once you have solved the problem(s), the reschedule will operate without displaying the warning popup again, unless a new problem is introduced.

Reschedule errors are also detailed in the reschedule report that you can choose to produce each time you reschedule a project.
