I’ve been experimenting with a few things in Open Plan and have found that it is possible to set up activity constraints in such a way that I end up with an Early Start date that is later than the Early Finish date.
For example, ’Fixed Target’ finish of 12APR10 and ’Not Earlier Than’ start of 26APR10. The activity has a 5 day duration.
The software allows this to happen and there are no messages in the log file about this. However I would like to know if this SHOULD be allowed. I would have thought one of the constraints would be ignored or at least a warning message should appear on screen when rescheduling.
Is it a software bug or is it conceptually possible?
