Hi Volker,
If an activity is deactivied, will all the constraints that contain this activity will be ignored?
For example, for constraints like a set of activities has a set of preffered time and a set of activities are not overlapping, they contain more than one activities. For instance, a not overlapping constraint R1 contains four activities,A,B,C,and D. If I deactivite A, will R1 be ignored thoroughly or B, C and D still be not overlapping with each other?
