I have a number of tasks which have 3 subtasks each that MUST start and be completed exactly 2 weeks from each other. (each subtask is half day) i.e. task1: (subtask1 @ day1, subtask2 @ day14, subtask3 @ day28)
The problem is that if I use lag, when I have many tasks (more than 200) and I level the resources, the subtasks2 of each task is pushed by the subtasks1 so they are scheduled more than 2 weeks from the linked subtask1)
I could use constraint but I need the tasks to float so if I change the starting day or the priority of the main tasks everything will be rescheduled maintaining a fixed 2 weeks delay of each subtask.
Any idea on how to do it?
