Partial reforecasting
Unlike reforecasting, where you recalculate the due dates and forecasted usages of all the tasks, in all the visits, for all the aircrafts in a plan, a partial reforecast involves recalculating the aforementioned dates and usages for a much smaller data set.
You move a visit, or multiple visits, on the same track. Every time a visit is moved forwards or backwards on the same track, they might impact or touch other visits on the same track. Partial reforecasting occurs for aircraft moved beyond the start date of the first moved visit, or the first visit that was affected.
You move a visit to a different track. See the details above.
You move a task to OVERFLOW. This creates a new visit with selected tasks, and has a span equal to the duration of the longest track moved.
You move a task to another visit.
You change the start or end date of a visit.
You add an ad hoc visit. Creating an ad hoc visit on a track will impact any visits that appear after the ad hoc visit on that track, as this will take the visit into account for ground time, affecting the due date and forecasted usage calculations.
