SYMPTOMS
When a Must Finish On Constraint is placed on a task, and only the Actual Finish date is entered, which is different from the Must Finish On date, the Actual Start, Scheduled Start and Duration are miscalculated.

WORKAROUND
The solution to this problem is to type in both the Actual Start and Actual Finish dates. If that is not possible, you must reset the constraint date as follows:


 * 1) In the Task Details Form, change the constraint date to the Actual Finish date.
 * 2) Choose the OK button.
 * 3) Enter the Actual Finish date.
 * 4) Choose the OK button.

This results in the duration remaining at it's original setting allowing the start dates to be calculated correctly.

Steps to Reproduce Behavior

 * 1) Set up a task with the following parameters:
 * 2) Enter an Actual Finish date of 7/20/92. This results in:

The start dates are not recalculated using the Duration. Instead, the Duration is recalculated from the new Actual Finish and the original start date.

An Actual Finish date earlier than the constraint date results in a zero duration with the start dates set to be the same date and time as the Actual Finish date that was entered.
