Hi all,

I read the Microsoft Project blog several times and experimented with this for quite a while and I came to the conclusion that doing this change, Microsoft introduced a bug in behavior of the Units field. The bug though is not what most people think it is.

I described and demonstrated this bug quit thoroughly in this post in the MSDN forum : https://social.msdn.microsoft.com/Forums/fr-FR/b15388a4-4bb3-4c82-9a75-d374b6d55074/assigned-units-not-showing-correct-value-revisited?forum=projectprofessional2010general

The problem is that not only does the Units field not behave the way many of us would like it to behave but it does not behave the way Microsoft claims it does.

In my demonstration, I show adding 4 resources with Units set to 80% to a Fixed Duration task with effort driven checked.

Now the first resources gets “Initially assigned” at 80% which is the expected behavior.
“Initially assigning” the second resource should have left the first resource at 80% but the second resource is also at 80% which is wrong; it should be at 40%. and the “Initial assignment” of resource 3 drops to 40% and it should be 27% and son on.

On of the MVP was able too reproduce the error but came up with an justification that unfortunately does not hold water.

I believe, MVPs and he whole community are fed up with this wrong behavior that they do not realize that the fix it is not even doing what Microsoft claims it should be doing.

Does anyone know how to get Microsoft’s attention on this fact?
