The lack of this functionality is causing our Project management team to not use Smartsheet as their primary platform. This is a must-have functionality.
Out team manages a comprehensive schedule listing 30 or more projects. It tracks the progress on hundreds of items through our fabrication shop which consists of nine or more departments that all have a hand in producing the items. Each project has shipping deadlines. When deadlines are linked using dependencies, a change of a scheduled date in its predecessors automatically changes the deadline date. Without some kind of constraint on the deadline, it's too easy to mistakenly extend an item's shipping date inadvertently. While all the constraints listed in the original post would be great, I'd be happy if we could at least click a checkbox that would trigger a warning to the user that the pending date change would alter the date a the flagged task line.
Fully support this request. The lack of this functionality, especially "finish no later than" will likely require that we stop our subscription and move to another platform. It's critical for our projects that certain milestones have locked in dates that help shape the overall project plan AROUND them.
It will be good to have the option to set firm constraints dates (deadlines) in the Gantchart so when you start adding duration for tasks, timelines do not move and pass deadlines requiring everything to be manually calculated backwards.
