How much of this file's activity ID list is shared with the schedule it is compared with. Low means they may be different projects.
A change to the contract completion date that the owner has approved. A request on its own does not move the date.

The schedule this one was measured from. You choose it; the previous submission is only the default.

When this schedule says the work will finish. It is the contractor's own forecast, not a contract date.
