Tasks don't obey predecessors if:



There are constraints
There are actual dates against the tasks

Can you post a copy of the file so I can look? or post a screen shot as an attachment?

Hi Julie,

See attached file.
The area I keep having problems with is the Summary Task "Design" and all its subtasks.
Despite the "Schedule from Project End Date", the tasks need to start as soon as possible, on or after 25.08.
The project is purely milestone driven, duration is not driving in this case.

I figured giving Line 3 a Start No Later than 25.08. constraint and Line 5 a "3SS" dependency would do the trick, but it won't.

Maybe I'm missing something fundamentally, but I got it to work before (see attached screenshot).
Line 3 has a SNLT constraint of 25.08. and all others seemingly fall into line with a ASAP constraint.
