[PS2007] - Keeping track of task last change information

[godrid]

Hi,

I would like to obtain a list of tasks in the project plan that has been
updated since a specific date. I plan to create 2 task custom fields "Last
Update Date" and "Last Percent Completion" to keep track of this last update
information. I plan to use macro to achieve it but I am not sure whether this
is possible in the first place. If yes, which event should I capture in order
to update the custom fields?

Regards
Godrid
