Task Updates have been approved but not showing in schedule

Hi all,

I have a team lead updating tasks (marking them 100% complete).  This is submitted to the PM for approval which is then seen in the approval centre and then approved.  This all works successfully.  However, the updated changes aren't being reflected in the schedule.  I have tried a few ways:

- Approving as PM then opening the schedule and clicking 'Publish'

- Setting the 'Manage Rules' to automatically publish

Then I thought maybe the plan had to be checked back in for changes to take effect but that made no difference.  Am I just not understanding how this process works???

Thanks,

Ann
