I noticed if you change a task status to Cancelled or On Hold, the Planned hours still remain in the Resource Planner, (as do the Projected Costs) which I feel is an unexpected and undesired behaviour. If you simply delete the task then all reference to it is lost which I don't think is always ideal.
The problem with Cancelled or On Hold tasks Planned hours remaining in the Resource Planner is it gives a false reading of the work remaining for a team or person.
You can't seem to add a Task level filter either to the Resource Planner to exclude Cancelled or On Hold tasks from calculations which is a bit annoying.
I feel you should be able to Cancel or put a task On Hold, and leave the tasks planned hours and assignments so you have reference of what was originally planned for the task (helpful for reporting and in case they are required again later), but have the ability to remove this information from resource planning and cost calculations later on, at minimum be able to filter it out.
