What happens when a sales quota plan is activated?

When you activate a sales quota plan the status of the plan is changed to completed when the plan year ends. You can't make changes to a completed quota plan.

When you activate a quota plan a process carries out the activation. Another process runs when the quota plan year end date is reached, or if it has passed at the time of activation. The second process changes the status of the sales quota plan to Completed. You can't edit a completed sales quota plan.
