The iterations function is designed for those tasks that are cyclical or nested, such as vehicle maintenance where certain activities are performed repetitively according to the mileage traveled, thus being able to overlap some of these tasks.
That is why, with the iterations function, it is possible to determine in which part of the cycle of a task each subtask should be executed and thus have a better control of the complete maintenance cycle.
To activate the iterations function, we must go to and select the task of the plan in question and click on the iterations tab and activate the "Set as cyclic task" option.
Then you have to indicate the number of iterations in which each cycle of subtasks will be divided, and then select which subtask will be performed in each specific iteration.
