Critical task definitions

i found this definitions of critical tasks:

A task becomes critical when it meets any one of the following conditions:

It has no slack.
It has a Must Start On (MSO) or Must Finish On (MFO) date constraint
(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].).
It has an As Late As Possible (ALAP) constraint in a project scheduled from
a start date.
It has an As Soon As Possible (ASAP) constraint in a project scheduled from
a finish date.
It has a finish date that is the same as or beyond its 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.)
date.
A task stops being critical when it's marked as completed, because it then
can no longer affect the completion of successor tasks or the project finish
date.

Seen what's above i don't understand why, if i create a new project
scheduled from the end date and i create a task that has an As Soon As
Possible (ASAP) constraint , Project doens't indicate me that task as a
critical task.

Thanks in advice for any help.

CPM (Critical Path Method) is base on all taks having logic ties. One this is
done the critical path is the longest path through the schedule. This is what
drives the end date.
You may want to set up a filter for critical path:
"Finish Slack Less Than 10 Hours" The 10 hours is what I use for
outages. You can also set up a second filte for near critical"
Finish Slack Less Than 15 hours
Finish Slack Greater Than 10 hours.
Hope this helps!
