CoConstruct will still record the confirmation for the existing published task. When you go to publish your Draft Schedule, CoConstruct will look at each task to determine if that confirmation is still valid. For instance, if the trade partner confirmed a task that did not change between the old schedule and new schedule, the confirmation is still valid. However, if the task’s details changed (such as new dates), CoConstruct will clear the confirmation and wait for the newly updated task to be confirmed again.
