I'm attempting to build a schedule and use MS Project to calculate dates and flow, based on constraints and task linking, but am unable to overcome an apparent issue with how the 'Late Start' is calculated for sub-tasks.
This is a simple schedule with two tasks, and a completion milestone, with a simple linear dependency structure, and a 'Start No Later Than' constraint on the final milestone. The 'Task Group' is a placeholder in this scenario.
The 'Late Start' dates calculated by Project here are working as desired and expected, moving back appropriately from the 'No Later Than' date.
Now, I move 'Task 2' to be a subtask:
Now, the 'Late Start' for tasks 1 and 2 are not what would be expected based on the task hierarchy and durations associated with the tasks.
Can someone help me to understand how I can create a set of grouped tasks that will set the 'Late Start' date appropriately, per the scenario above?
