If you changed your company's default method of tracking progress, did you
also "lock down" this method on the Tracking Settings page in PWA? This is
so that your project managers cannot select their own method of tracking
progress in the Microsoft Project plan by clicking Tools - Customize -
Published Fields. If you did not lock down your method of progress, you
probably should do so.
After you selected a new default method of tracking progress, did you
republish the assignments in EVERY project? To do so, open every project
and click Collaborate - Publish - Republish Assignments and then click OK.
Doing so will "push" the new method of tracking progress to each user's
timesheet in PWA.
In addition, you should know that the tracking method will only be changed
on tasks in which no progress has been entered. Those tasks that appear to
be read-only are probably tasks where a % Work Complete value has been
entered by the team member.
Now, answer a few questions for me and then I will have a solution for you
on how to "unlock" those read only tasks. First of all, how many projects
do you currently have in your portfolio of projects? How many of them are
published? About what percentages of tasks have had progress updated by
team members in PWA using the old method of tracking progress? I need to
guauge "how far down the road" you folks are with your implementation, and
then I can give you an answer. Let me know.
