I want to fixed a date for a task (this task HAVE TO be the very first week of april). But this task also depend on the end of other task, then I want to put a dependency. But when I add a “predecessor” constraint, the scheduler move my task.
I saw that this subject has already been discuss en 2015 (“Fixed milestones #125”), and that a branch of the soft (the “issue_125 branch”) is said to include this feature, but with the actual version I still do not succeed to do it.
Any help ?
