Assumptions before reschedule:

  • Task 1 Finish Date: 1/30/2011
  • Task 2 depends on Task 1 by Finish-to-Start constraint (without any leads/lags) and thus start on 1/31/2011

After reschedule, Microsoft Project did this:

  • Task 1 Finish Date: 2/15/2011
  • Task 2 Start Date: 2/15/2011

As you see, MSP starts Task 2 exactly from day Task 1 is finished (2/15/2011). This is while, I suppose that Task 2 starts after Task 1 is finished (2/16/2011) due to the FS constraint. Can someone explain why MSP 2013 didn't start Task 2 on 2/16/2011?

    Go to settings and select a date-time format that includes the time of day. You'll find Task 1 doesn't finish at the end of the day. Trace back until you find your error. – Tom Boyle Nov 14 '17 at 5:24
  • true, now how can I make MSP start Task 2 from new day (day after finishing day of Task 1) ? – DavidDe Nov 14 '17 at 5:52
  • You could always just type in the day you want at the Start of Task 2, but I suspect you want to do it right. What are the durations and start and finish dates (including time of day) of Task 1 and Task 2? – Tom Boyle Nov 14 '17 at 18:55
