My MVP Fellow, Dale Howard found this Bug in MS PROJECT 2013!
I will Create brand new Project with some Tasks:
Now, suppose that I want to make First four Tasks inactive:
I will get:
So far so good. Now, let’s say that all Task (active Tasks) which are supposed to be Finished at Friday, 16.5.2014 are finished. Notice that 16.5.2014 is date which is AFTER all inactive Tasks. I’ll do this like this:
and I’ll get:
As you can see, Inactive Tasks are marked as Completed. The funniest thing is if you try to Select one or many of those Inactive Task and then try to make them 0% Complete, it is impossible!
This is a Bug!
