Good scheduling software does not enforce impossible schedules; in case there is an attempt to model such scenarios it will enforce a realistic solution. Then the scheduler will take notice and if necessary, make manual adjustments.
Among the impossible scenarios are the infamous loops. These loops can be created by mean of logic links as well as by means of date constraints. As I use software that does not enforce impossible schedules I will present a scenario with impossible to meet date constraints on a single activity, it will yield a realistic solution. I do not have P6 so please mimic the scenario in your software and let me know if it created a loop. Hoover the following image and zoom.
