Both the software are used worldwide and they have their own benefits. The following are the differences between Primavera Software and Microsoft Project 2010 Unique ID: Microsoft Project, the first line is assigned ID 1, the second line ID 2 and so on.
If you insert a new activity between 1 and 2, the new activity becomes ID 2.
Eg, when i try it: Visble range is A1: BC79, so this code selects A80 and scrolling down and to the right and running it again reveals the excel chooses the first cell NOT visible below the first visible column.
They are the most popular software for project planning, reporting, progress updating and tracking.
If you are working in a big project and using activity ID system/ Identification then Microsoft Project will not be the correct choice.
