What feature enables you to allocate values from a year column into months on a standard sheet?

Breakback is a specific data entry feature in Workday Adaptive Planning that enables top-down planning. When a user enters or changes a value in a summary time period (like a year or quarter), Breakback automatically allocates or "breaks back" that total to the underlying detail periods (months) based on their existing proportions. If no data exists in the detail periods, it performs an even spread. This directly matches the described functionality of allocating a yearly value into months.

A. Splits are used to spread a value from a single source month forward into multiple future months, not from a summary period down.
B. Copy Forward copies a cell's value to subsequent periods, which is a different function from top-down allocation of a total.
C. Adjust allows users to increase or decrease values by a specific amount or percentage, but it does not allocate a summary total.
