The "Rollup" calculation rule is specifically designed to aggregate data up the defined business hierarchies, such as Entity and Account dimensions. This process sums the values from lower-level (child) members to their respective higher-level (parent) members. Running this rule is essential after data input or changes at the base level to ensure that consolidated totals are accurately reflected in reports and analyses at all summary levels of the organization.

B. Prepare Plans: This rule is used to initialize a planning scenario, typically by seeding it with data from another source like actuals or a previous plan, not for hierarchical aggregation.

C. Calculate Actuals: This rule executes specific calculations on the "Actuals" scenario data, such as deriving financial ratios or other calculated metrics, rather than performing a general aggregation.

D. Prepare Forecast: Similar to "Prepare Plans," this rule is used to initialize a forecast scenario, often by seeding it with a combination of actual and plan data.

Section: "Financials Business Rules"

Content: This section explicitly describes the out-of-the-box rules. It states

"Use the Rollup business rule to aggregate data through the Entity and Account hierarchies." It also defines the other rules: "Use the Prepare Plan business rule to seed your plan from Actuals

" "Use the Prepare Forecast business rule to seed your forecast from Actuals and your current plan

" and "Use the Calculate Actuals business rule to calculate actuals for all Financials accounts." This directly supports 'A' as the correct answer for aggregation and differentiates it from the other options.

Section: "About Aggregating and Calculating Data"

Content: This document provides the foundational concepts

explaining that aggregation (a rollup) is the process of calculating data for parent members by consolidating the data of their children. This aligns with the function described in the question as necessary to "analyze data at various levels of the business hierarchy."
