Enforce Spend Plans
By default, if you do not want to add a spend plan to a project right away, they can be added later by editing the project. If Enforce Spend Plans is enabled, you can no longer create projects without spend plans. For more information, see What is a Project Spend Plan?
Forecasting
Forecasting generates an estimate of your future spending based on your current spending. It uses a linear projection that is based on this month's spending and trend data from previous months.
