When an activity is deactivited, all constraints contain it will be ignored?

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?
