Which three actions are available when using the mass update multiple values of a single metric of a sales agreement terms tab?

When using the mass update multiple values of a single metric of a sales agreement terms tab, the

three actions that are available are: replace with, decrease by, and increase by. These actions allow

the user to update the values of a metric across multiple periods and products in a sales agreement.

For example, the user can replace the forecasted quantity of a product with a new value, or increase

the discount percentage of a product by a certain amount. The other options, update with and

multiply by, are not valid actions for mass update. Reference: Mass Update Account Forecast
