Actual duration and Actual start “problem” in MS PROJECT 2019


I have a question from blog reader:

“Hi Nenad,
I would like to track the progress in the following scenario:
Task A: 3,5 d duration
Task B: 3 d duration with a constraint FS with task A
Progress: Say that Task A is on track (Actual start date: 11/02; Actual duration: 3,5 d; Rem. duration:0 d)
Task B starts 14/02 actual duration 1 d; Rem. duration:2 d
What I get is not what I want because Task B starts when Task A isn’t yet finished.
Then it is necessary to enter in the actual start date of Task B also the time.
In this case it is easy  but in more complex projects it could be more difficult and above all more boring.
Is there a tip to avoid this?”

Here is the Project:


Since Task A is finished on time, and it was started on time I will mark it as 100% completed;

imageand I will get:


Now, Task B has started on time, and Actual duration is 1 day, with Remaining duration 2 days.

image and:


and I will get:


The Problem is that Actual start of Task B is 14.02.2019 at 08:00, but Task A, has finished at 12:00 same day, so it seems that Task B has been started before Task A has been finished. Why? Because if I put Actual start date, it will take start time from Calendar. To avoid that just DON’T put anything in Actual start field like this:


Final result is, as expected:


So when Task has been started immediately after predecessor is finished, leave Actual start field empty.

Hope this helps!
