Tips on using this forum..

(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?

(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.

Hi Rizwan,

The Original duration is the number of working days required to complete each activity based on the current schedule. However, At completion duration is the sum of the actual duration and the remaining duration.
