(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?
(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.
If you need strict enforcement of contiguous performance point-to-point relationships can enforce it preventing an undesired result. As expected project will be delayed in order to meet the resource constraints and continuous performance requirement. A requirement common in manufacturing production lines.
