What feature allows the creation of subrows with values rolling up?

The feature that enables the creation of subrows with values rolling up is known as splits. When using splits in Workday Adaptive Planning, you can divide a row into multiple subrows, each representing a distinct level of detail or categorization. This is particularly useful for detailed reporting and analysis, as the values of the subrows can aggregate or roll up to reflect the total value in the parent row. By allowing data to cascade in this manner, it enhances the clarity and readability of information for users, providing insights at a granular level while still maintaining the overall context and totals in the parent row.

In contrast, merges are focused on consolidating data from multiple rows into one, clones allow users to create a copy of existing data or structures, and groups are used primarily for organizing related items together without the specific rolling up functionality associated with splits. This distinction is what makes splits the correct choice for creating structured subrows that reflect accumulated values.
