I have summary task in auto schedule and subtasks are manually scheduled. start and finish dates are rolled up to the summary tasks properly, but the only issue I still have is the total hours is not rolled up as a sum of individual hours of subtasks. please note that I have durations in hours. summary task is showing start date of July 2, 2014 and end date as Jul 31. 2014 which is correct BUT the total duration is 170 hours now, whereas I want it to show 40 hrs (i.e. sum of all subtasks hrs). Thanks for any possible help.
