Loops and Cross-Program Relationship
In BigPicture, task links have a direct effect on the Start and End Dates, so some combinations of links will not be allowed. This concerns what we call "loops". Let's imagine the following type of inter-dependency:
Task A (Ends) → (Starts) Task B
Task B (Ends) → (Starts) Task C
Task B (Ends) → (Starts) Task C
Please note that the same effect can be achieved using only 2 tasks.
Such a combination of links on these tasks would result in Task A rescheduling Task B, Task B rescheduling Task C, Task C rescheduling Task A, and so on and so forth. This sort of paradox would create an infinitive number of re-calculation and could possibly crush our environment. This is why our app Power-Up will not allow it and will return a Warning.
