Symptoms

New linked Activities in a new Project with a new Project Calendar are Scheduling At Completion Duration slightly less than Original Duration (OD) when the Calendar has a big block of non-work time. Observe the difference if preferences have duration in days with 1 or more
decimal places - Original Duration = 5.0, At Complete Duration = 4.9.

STEPS TO REPRODUCE:
1. Add new Project.
2. Create a new Project level Calendar from a 8h/5d Global Calendar.
3. Edit the Project level Calendar to have two weeks of consecutive non-work days.
4. In the Activities screen, show the Calendar and At Completion duration columns (save the view if needed). Add a few Activities with 40h OD each.
5. Add links between the Activities (by selecting all, right clicking and clicking link selected Activities).
6. Assign the new Project Calendar to all Activities using the Fill Down feature.
7. Save and Schedule the Project then refresh the page.


ADDITIONAL INFO:

Same Activities show At Completion Duration = Original Duration in Professional.

EXPECTED RESULTS:

Activities show At Completion Duration = Original Duration in EPPM and Professional.
