how do I calculate total of subtasks into summary task duration?

[SV]

I am putting in duration in hours and divided the tasks into subtasks and
summary tasks. but the summary task is not showing the total of the subtasks
duration. how do I add the duration of all the subtasks and fill up the same
in duration field for the summary task?

Hi SV,

Welcome to this Microsoft Project newsgroup

You can't! Duration, by definition, is the working time between the task
start time and its finish time. The Duration of a Summary is thus the
working time between the first task and the last task, and can only equal
the sum of the sub-tasks if their precedences are linked in a single chain.
You cannot therefore enter a Duration of a Summary task as this will always
be calculated for you by Project.
