Microsoft Project 2013: A summary task shows a wrong total of DURATION HOURS: The sum should be 31 hours, but it shows only 25 hours. However, the sum of WORK HOURS is correct. Also, the calculation of costs is correct. So, somewhere, 6 hours just in the duration are missing.
- The summary task has NO resources assigned.
- The summary task has NO predecessor assigned.
- All tasks below the summary task have the same resource, all at 100% capacity.
- In the tasks below, work and duration are all equal, which is correct.
So what could be wrong ?
